Could Golf Balls Be the Answer to Helmet Noise?

While we tend to think of helmet safety in terms of crash protection, another aspect, usually overlooked, is considerably important: wind noise. I can tell you as someone who makes his living off riding motorcycles, I am deathly afraid of losing my hearing from bike and helmet noise, and thus always wear earplugs while riding. I have yet to see a helmet on the market that truly eliminates wind noise to a level that can’t cause hearing damage, and of course that comes with a trade-off for ventilation. When given the choice, I’ll take the helmet that breathes, and keep my earplugs at the ready. Louie Amphlett, a recent product design graduate from the University of Brighton in the UK hopes to have a solution for me and my ears though: a helmet with golf ball dimples on its shell, which he calls the Lenza One.

Carl Sorensen Has Died While Practicing at Pikes Peak

Tragic news comes to us today from Colorado, as racer Carl Sorensen died during today’s practice session for the 93rd Pikes Peak International Hill Climb. With the motorcycles on the top section of the mountain, Carl crashed in a fast left-hand turn, known to have a bump on the racing line, near the summit. Familiar with the PPIHC race course, Carl finished last year’s hillclimb an impressive 16th overall, and 10th in the competitive “Open” class on his Kawasaki Ninja ZX-10R. For this year’s race, he made his move into the middleweight class, riding on a Ducati 848 Superbike. An avid motorcycle racer, Carl is survived by his wife and son, and will be sorely missed by all his family, friends, and racing compatriots. Our hearts and thoughts go out to all of those affected by Carl’s passing.

Track-Only KTM RC16 Expected to Cost €140,000

The motorcycle world is still processing Honda’s decision to make a road-going version of its RC213V MotoGP race bike, and whether you think its price tag overwhelms, or its spec-sheet underwhelms, the Honda RC213V-S is a testament to the engineering that HRC is capable of producing for its racers. KTM has a similar philosophy afoot. Though Stefan Pierer has made it clear that there will be no successor to the KTM 1190 RC8 R street bike, the company will be making a track-only customer version of its own MotoGP race bike: the KTM RC16. As we get closer to 2017, we will learn more details about the company’s 1,000 V4-power GP bike, and its customer counterpart as well, which is due in the second-part of 2018. For now, we get word that it will cost a mere €140,000.

NASCAR Powerhouse Could Takeover Laguna Seca Ops

The operation of Mazda Raceway Laguna Seca could be set to change hands, as Monterey County officials have confirmed that they are in negotiations with the France family’s International Speedway Corporation (ISC) to takeover operations at the rack track. ISC should be a familiar name to NASCAR fans, as the corporation not only built Daytona International Speedway, but the company’s primary business is owning and operating NASCAR race tracks (roughly half of the NASCAR season takes place on an ISC-owned track). Owning 13 tracks in all, ISC could add another if its deal with Monterey County goes forward, supplanting the nonprofit Sports Car Racing Association of the Monterey Peninsula (SCRAMP), which has operated Laguna Seca since its inception in 1957.

Monty by XTR Pepo

The “Monty” is the latest build from XTR Pepo, and as you can tell from the styling, this is the work of the same mind that brought us the Radical Ducati. Pepo has since branched out from Ducatis though, taking on other brands, so it shouldn’t surprise us that the Monty started life as a 1978 Laverda 500 Alpino — the name being a nod to the Laverda Montjuic, which was based off the Alpino, and affectionately called “Monty” in-short by its owners. While there are a number of Laverda parts in the build, if you look closely at XTR Pepo’s Monty, you will see the swingarm from a Suzuki Bandit, front forks from a Ducati Monster, a GSX-R600 clutch lever, and Honda CBR600RR footpegs — all in the name of continuing of XTR Pepo’s motorcycle pick-and-pull build style.

How About Some Halo Bike Spec-Sheet Racing?

With the Honda RC213V-S debuting at Catalunya last week, much has already been said about Big Red’s road-going GP bike…especially in terms of how it compares to other halo bike motorcycles that have been 0r currently are on the market. So, in the interest of exploring solely the most basic attributes from a motorcycle’s technical specification sheet, we have compiled a spreadsheet to see how the Honda RC213V-S stacks up against its most analogous street bikes. As such, we have compiled the horsepower, dry weight, and cost of the the Ducati Desmosedici RR, Ducati 1199 Superleggera, Kawasaki Ninja H2R, MV Agusta F4 RC, EBR 1190RS, and Yamaha YZF-R1 motorcycles — you can see the easy-to-read chart (after the jump), and make your own comparisons to the RC213V-S.

Report: KTM 390 Adventure Begins Testing in India

It’s been a while since we heard about the KTM 390 Adventure, the Austrian company’s third installment to its built-in-India small-displacement motorcycle lineup. Based off the KTM 390 Duke, the Adventure model has been a long-time coming, ever since KTM CEO Stefan Pierer lit it slip that the dual-sport would be coming, two and a half years ago. It seems now that KTM is getting closer to production, as the folks at CarTrade are reporting that two test models of the KTM 390 Adventure (codenamed KT22) have been sent to India for R&D, presumably as a prelude to Bajaj beginning production on the budget-friednly machines.

Is This What a Modern Honda NSR250R Would Look Like?

The Honda NSR250R is a special machine. When the 249cc, tw0-stroke, 90° v-twin GP bike with lights first hit the streets of Japan, it cost roughly $7,500 in hard-earned American dollars — a tidy sum back then, especially for a 300 lbs machine that made 40hp stock. A coveted item for motorcycle collectors and discerning track riders a like, you can pick one up for over $10,000, the limited-production road-going version wasn’t terribly different from the 250GP World Championship bikes that factory teams were racing. A topical reminder, if we do say so ourselves… So how do you improve upon such a great machine? Ask the folks at TYGA Performance, who have been tinkering with NSR250R sport bikes since they opened in 2000.

Will MV Agusta Be Reviving the Cagiva Brand? Should It?

Talking to the Varese News, MV Agusta Executive Vice President Giorgio Girelli let slip a number of interesting tidbits about the Italian company — the biggest news of course concerns another company, Cagiva. Acknowledging the circulating rumors about the revival of the historic brand, Girelli was quick to point out that it’s not in the company’s current plan, but that the possibility was certainly there. Going further about the idea, Girelli suggested that Cagiva would make the most sense as a purely off-road brand, which would compliment MV Agusta’s pure on-road offerings.

Here is the $184,000 Honda RC213V-S Street Bike

Honda has finally debuted its “absolute MotoGP machine for the street” – the highly anticipated and hyped Honda RC213V-S. First off, the rumors are true: this is not going to be an affordable motorcycle. The 2016 Honda RC213V-S will cost $184,000 in the USA, with each of the 200 or so units will be hand-built at Honda’s Kumamoto factory. With different versions for different markets, Honda says that the RC213V-S tips the scales at a claimed 170kg dry weight (190kg wet) in the USA, which isn’t exactly mind-blowingly light. Even more disappointing, the Honda RC213V-S will be tuned for 101hp at 8,000 rpm (66 lbs•ft of torque) for the American market, and the power-boosting sport kit will not be available to the US buyers.

Valentino Rossi to Test New Aluminum Frame at Jerez

09/21/2011 @ 8:57 am, by Jensen Beeler15 COMMENTS

According to both GPone and MCN, Valentino Rossi and Ducati Corse will test a new aluminum frame at Jerez this week. Though the two MotoGP authorities differ on what sot of frame exactly will be used during the test (MCN says twin-spar, while GPone maintains an “open cradle” frame that leaves the motor still as a stressed object). Regardless of the style, the new chassis is reportedly made by FTR, and is another attempt by the Italian racing team to figure out how to solve the vague front-end feeling coming from the Ducati Desmosedici GP11/GP11.1/GP12.

Possibly similar to the chassis style used by Honda and Yamaha, this new frame design marks the fourth major chassis change this year for Ducati. Unable to compete against the top pack on the grid, Rossi has lately even struggled to keep up with his fellow Ducati riders come race day. While technically considered a test for the 2012 season and on the GP12 motorcycle, the results from the Jerez test (Ducati’s seventh test of an allowed eight) could easily find its way onto this season’s Desmosedici.

Valentino Rossi to Use Aluminum Chassis at Aragon GP

09/15/2011 @ 12:31 pm, by Jensen Beeler12 COMMENTS

Valentino Rossi finally put an end to the speculation today at the MotoGP pre-race press conference, and announced that Ducati Corse will use an aluminum chassis during the Aragon GP this weekend. First tested last week on the Ducati Desmosedici GP12, the FTR-built aluminum frame has improved the front end feeling for the Desmosedici, an issue that has plagued the Ducati all this season. Rossi will first use the new aluminum parts during Free Practice tomorrow, though the team hasn’t confirmed their use in the race just yet.

“We tested last week after the race, and it was not so bad,” said Rossi when talking about Ducati Corse’s post-Mugello test. “We tried something different on the bike to improve the front feeling and turning, and the lap times were not so bad. I was a bit faster than the last time, and basically the feeling was quite good, so we’re moving forward.”

When pressed about what changes Ducati made, and whether or not Rossi test the rumored aluminum frame, the nine-time World Champion was quick to correct. “It is not a frame,” explained Rossi. “The philosophy of the Ducati is the same, but the front part of the bike is a bit different, and is in aluminum, and not in carbon like before. But about the material, it is a question of time. We have to work to try and understand how the bike and with aluminum you need a lot less time compared to the carbon. The bike improved a bit, but this is just the first step. We need to keep working to come back and fight for the front.”

Filippo Preziosi: “The Two-Cylinder is the Best Engine, If You’re Not Constrained by Rules”

08/16/2011 @ 1:35 pm, by Jensen Beeler15 COMMENTS

Head of Ducati Corse, Filippo Preziosi is a busy man under regular circumstances, and with the shenanigans going on in Ducati Corse’s MotoGP team right now, the former motorcycle racer is a hard man to get a word with, let alone on a race weekend in Brno. Somehow catching up with Preziosi during MotoGP’s Brno test, our friend David Emmett at MotoMatters, along with several other journalists, sat down with Ducati’s Maestro of MotoGP to ask him about where the Italian team was headed, and the challenges it is currently facing.

There is of course a tremendous amount of chatter going on in the MotoGP paddock about Ducati’s “frameless” carbon fiber chassis, a switch to an aluminum twin-spar frame, the Bridgestone tires, and Valentino Rossi’s psyche, all of which Emmett has already summarized for us in his detailed analysis of Ducati Corse’s situation. Taking on all of these issues, Preziosi sheds some insight on what is going on behind the scenes at Ducati, and is candid about what issues they are and are not facing.

Dismissing out right that the “L” engine configuration is at least partially to blame for Desmosedici’s lack of front-end feel, one of the more interesting points Preziosi makes is his preference for the v-twin motor. Acknowledging that the package will perhaps make less power/torque than a four-cylinder, Preziosi opts for instead the two-cylinder’s rideability, and if the rules allowed it, the motor’s weight advantage over the inlines (this of course coming from a man who has figured out how to make a v-twin without the weight of a traditional frame).

His comments raise some interesting thoughts about the way rules are constructed in motorcycle racing classes, and perhaps speaks to the central issue occurring MotoGP: that the rules are pigeonholing the development of GP motorcycles into one particular slot, that just happens to be a four-cylinder motorcycle with a conventional frame that reacts to a prescribed tire construction methodology. Preziosi makes some other interesting comments that read well between the lines, check them out in transcribed interview after the jump.

An Analysis of the Troubles with the Ducati Desmosedici

08/09/2011 @ 2:16 pm, by Jensen Beeler4 COMMENTS

The obvious point to make in the 2011 MotoGP Championship is that Ducati Corse is struggling to compete with Yamaha and Honda, despite having the G.O.A.T. himself, Valentino Rossi, riding for the Italian squad. The recent history of the Desmosedici is fraught with bullet points of issues, most of which coming back to the bike’s notoriously vague front-end. Though showing moments of promise, even brilliance, including a World Championship with Casey Stoner at the helm, the Ducati Desmosedici has earned the reputation as a career-ender and a confidence destroyer among its less fortunate pilots.

When the dream team of development came to Ducati, in the guise of Valentino Rossi and Jeremy Burgess et al, the talk before the 2011 season was that the nine-time World Champion and his perhaps even more impressive garage crew could have the Desmosedici figured out in no-time at all. With the now infamous quote from Burgess that the GP10 could be sorted out in about 20 seconds still resonating in the MotoGP paddock, we stand now well over half of the way through the current MotoGP season, and the Championship standings hide what’s been apparent from day one: the Desmoproblema requires more than a quick-fix.

The solution to fixing the Ducati Desmosedici can be broken down into three camps, and depending whose opinion you solicit, you’ll get one of the following causes for Ducati’s uncompetitive season: the motor, the chassis, or the rider. Walking us through that analysis is our good friend David Emmett (bookmark his site MotoMatters.com right now), who may not be the most astute automatic transmission driver we’ve ever seen, but when it comes to comprehensive MotoGP analysis, the man is second to none.

Putting together an exhaustive digest on the issues that are surrounding Valentino Rossi, Ducati Corse, and the Desmosedici, Emmett weighs and measures the different dynamics of the problem at hand. Head on over to MotoMatters with your beverage of choice in-hand, and hear what MotoGP’s most-enlightened journalist has to say on the biggest subject in MotoGP.

Recall: Kawasaki KLX 250

07/07/2011 @ 12:27 pm, by Jensen Beeler1 COMMENT

Kawasaki is recalling 9,460 units of its 2009 & 2010 Kawasaki KLX 250 dirt bikes because the fuel tank may leak at the spot weld(s) on the side mount tabs. Caused by excessive clearance between the fuel tank and frame-mounted rubber damper, the fuel leakage at the welding point(s) could ignite and cause a dangerous explosion.

MotoGP: Ducati Racing with 2012 Chassis Starting at Assen

06/20/2011 @ 6:38 pm, by Jensen Beeler20 COMMENTS

Ducati Corse continues to battle a war on two-fronts: both by trying to market itself out of an otherwise disastorous MotoGP season, and also to rapidly develop and search for answers to the lackluster Ducati Desmosedici GP11. The latest news out of Bologna now leans more towards this latter effort (or is it the prior?), as Ducati Corse has announced that it will bring a version of its 2012 chassis to Assen for Valentino Rossi to use in the Dutch TT.

The Ducati Desmosedici GP11.1, as they’re calling it, features a modified motor, and will debut Ducati’s next-generation gearbox: the Ducati Seamless Transmission (DST). Ducati hopes bringing out the new chassis, which has already been given the nod by both Rossi and teammate Nicky Hayden, will not only help turn around the season’s results, but also expedite development for the Ducati Desmosedici GP12. Along with a new carbon chassis, the GP11.1 features an inverted swingarm design, which sees the rear shock mounted higher-up with a special rear-subframe assembly.

Zero MX Frame Failure In Switzerland

04/28/2010 @ 12:32 pm, by John Adamo14 COMMENTS

Zero MX Motorcycle Frame Failure

Last weekend Tommy Heimburg, owner of ERIDE Motorcycles crashed his Zero MX at Motocross Wohlen track in Switzerland. The frame of the Zero MX broke behind the head tube. It seems this failure may have caused the crash. The history of this Zero bike is unknown as it was owned and race by a private party but obviously there is concern that this could happen to other Zero MX motorcycles and may cause a risk to owners.

Ducati Applies for Frameless Motorcycle Patent

03/19/2010 @ 3:30 pm, by Jensen Beeler19 COMMENTS

Modular motorcycle design is the wave of the future, and it would seem Ducati agrees with this same sentiment that we’ve been harping on for the past 9 months or so. Perusing through the USPTO’s records for patent applications, we found this interesting nugget submitted by Ducati Motor Holdings S.p.A. Known better as Patent Application #US 2009/0308677 A1, or “Simplified Motorcycle”, Ducati’s patent application outlines a motorcycle that is devoid of a frame, and instead has all the components of the motorcycle bolt on directly onto the motor.

Hands on with the MotoCzysz Frame

03/18/2010 @ 3:31 pm, by Jensen Beeler2 COMMENTS

Ending our two-part series that looked at the the MotoCzysz E1pc, we ask ourselves: why do motorcycles look the way they do? Probably the best answer to this question is that motorcycles today represent an amalgamation of 100 years of design evolution centered around the internal combustion engine. When we look at motorcycle racing, we see the design in its purest embodiment of function over form. While surely some semblance of aesthetics remains, the ultimate goal is to shave the next tenth of a second off a lap time. Each minor improvement adds up, and these aggregated can translate into substantial improvements when racing the clock and the competition.

So it surprises us when we look at electric motorcycle racing and see so many teams approaching their designs with the same ideas and concepts that were born out of this century of internal combustion engine (ICE) racing. While the two offshoots of the same branch carry over with them many similarities, the fundamentals of attaching wheels, suspension, and seat to a running motor has changed, and with that change surely there would be a large movement to rethink the way we build motorcycle frames. The fact of the matter however is that many electric motorcycle designers choose to pursue cramming an electric motor and batteries into a frame, and ultimately into and architecture, that was refined for a gasoline pumping motor and doesn’t fully integrate the chassis’s from with its function.

In an industry that rethinks motorcycles from the ground up, the biggest paradigm shift has been left out by all but a few teams and manufacturers. Looking for the next generation in motorcycle chassis design, Asphalt & Rubber recently got to sit down with Michael Czysz to get an up-close look at the 2009 MotoCzysz E1pc electric motorcycle, and also got a sneak peak at the 2010 frame and chassis. As one of the few entities to rethink how a motorcycle should be design and produced, Czysz’s insights into his design give a glimpse as to what the next 100 years of motorcycle evolution will look like.

Suzuki GSX-R1000 Safety Improvement Campaign

01/28/2009 @ 2:44 pm, by Jensen BeelerComments Off on Suzuki GSX-R1000 Safety Improvement Campaign

suzuki-gsxr-wheelie

Suzuki has initiated a safety improvement campaign, which is not a recall…but kinda really is totally a lot like one…sorta. A safety improvement is not conducted under the United States Safety Act,  but is carried out when a manufacturer voluntarily modifies or replaces a vehicle already out on the road. This one is in regards to a potential frame problem with the 2005 and 2006 GSX-R1000, which means it affects over 26,000 motorcycles.

The safety improvement is being conducted because cracking or breakage of the bike’s frame can occur in certain extreme situations where unusually high stress is placed on the frame. Repeated hard landings from hazardous maneuvers such as extreme or extended wheelies or other stunts may generate sufficient stress to cause this problem. If the frame becomes broken during extreme use, a crash could occur.

Gixxer 1000 owners should take their bike down to the local Suzuki dealer for an inspection for cracks. If no cracks are found, a frame reinforcement brace will be attached to the frame using bolts and epoxy adhesive. Should cracks be found during the inspection, the frame will be replaced with a new frame that has the reinforcement brace installed. The campaign began on January 21, 2009. Owners may contact Suzuki at 1-714-572-1490.

There’s a certain irony to this article that we can’t quite place our finger on…
