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.

motoDNA: Emergency Braking Techniques

Emergency-Braking-motoDNA-02

Nothing causes as much confusion or trepidation in riders as emergency braking. How hard can I brake? Will the front wheel lock? Will I go over the handlebars? How far can I lean over on the brakes?

As a Motorcycle Instructor I am continually amazed at how many of our students, who have generally had some training and are licensed, come to us with inadequate braking skills. It’s super important to understand and regularly practice emergency braking on your bike. Normally I recommend a quiet car park with a slight up-hill.

To understand braking we must first understand grip. The main contributor to grip is the weight or load on each tire. The ratio between the maximum possible grip and the vertical load is called the coefficient of friction (μ). To understand this, slide an eraser across your kitchen table. Now try the same thing pushing down hard on the eraser.

This same thing happens when you brake on a motorcycle. The bike pitches forward transferring weight onto the front wheel, increasing front tire grip. More so with sports bikes, tall with short wheelbase compared to cruisers, which are long and low.

motoDNA: Getting a Grip on the Mechanics of Trail Braking

03/07/2014 @ 2:44 pm, by Mark McVeigh18 COMMENTS

motoDNA-trail-braking-05

On the track, racers are either on the throttle or on the brakes – no free wheeling – this wastes time. Trail braking is a technique which racers use to slow the bike as quickly as possible from one speed (on the straight) to another (corner apex speed).

In applying this technique, a racer will approach a turn and at their braking marker, apply full braking force, normally with the bike being upright.

As the rider begins to turn in, they reduce brake pressure, easing off the brakes. Decreasing or “trailing” the brake lever force as the bike lean angle increases until they gets to the apex, the rider then releases the brake and applies the throttle.

Sounds easy enough in theory, but proper execution is complicated because it comes down to feel — and remember these guys are doing this seamlessly, every lap on the limit.

As Freddie Spencer once said, “fast riders have slow hands” so all this is done smoothly, progressively and powerfully.

PSA: Please Reconsider Using Your Rear Brake

There is a weird phenomenon as one gains experience on a motorcycle in regards to the usage of the rear brake. As novice riders, we are taught to use the rear brake in conjunction with the front brake, and in rider training courses like the one put on by the MSF, this is a skill that is practiced out on the range. Out on the road, it is not uncommon then to see the rear brake light of a new rider dance with light, as a foot covering the rear brake toggles the brake light switch on and off.

As we progress and gain some more experience as motorcyclists, the trend is to stop using the rear brake entirely — relying solely on the front brake for our stopping needs. Go to enough track days and eventually you will see a motorcycle fail a tech inspection because the rider thought the rear brake was so unnecessary as to remove it completely from the machine — for the weight savings, of course.

As a rider’s skill set on a motorcycle improves though, a new love affair is found with the rear brake. Talk to any professional motorcycle racer about their rear brake, and you will begin to realize there is a huge role that the rear brake plays in bike stability, which at times makes no sense to a layman — something exemplified by Casey Stoner’s frequent use of the rear brake while also hard on the throttle.

Not quite diving that deep, Scott Russell (of Mr. Daytona fame) and Nick Ienatsch (of FasterSafer.com) explain why you should fall in love again with your rear brake, as well as giving some tips on how to modify your bike to get the most out of braking with both the front and rear tires. Enjoy!

Video: Got Brakes?

06/12/2012 @ 2:49 pm, by Jensen Beeler20 COMMENTS

Whether your Sunday mornings are spent watching the AMA, BSB, WSBK, or MotoGP Championships (bonus points if nodded for each one of those), the image of watching a motorcycle lift its rear-wheel off the ground under heavy braking is surely a common occurrence to you. For amateur racers, the experience can be a bit unnerving at first, and even the professionals sometimes miscalculate the available traction, braking distance, and entry speed associated with such a maneuverer.

Such was the case with one Brazilian Superbike racer, who found himself on the wrong side of an endo, and headed into slower traffic at a corner’s entry point. With his rear-wheel lifted well off the ground, our protagonist makes perhaps the worst decision for the situation: he grabs more front brake. The rest writes itself, and we again thank the proliferation of on-board cameras in modern motorcycle racing for bringing us another tasty clip. Video after the jump.

The Top 10 Late-Brakers at Mugello

07/05/2011 @ 4:45 pm, by Jensen Beeler8 COMMENTS

Brembo has released a list containing the Top 10 late-brakers at the Italian GP in Mugello. Taken from teams’ telemetry from the Qualifying Practice, Brembo compiled the list based off who was applying the most braking force coming off the front straight-away, and into Turn 1. Of note, the list was based off only teams who use Brembo brakes, which means LCR Honda and San Carlos Gresini Honda were left off the list (they use Nissin), we therefore don’t have data for Toni Elias, Hiroshi Aoyama, and Marco Simoncelli.

The San Donato bend at Mugello sees riders slow from 203 mph coming down the long straightaway to 75 mph into the apex of the first turn. One of the first tracks on the MotoGP calendar, Mugello recently repaved its course, meaning the Italian track has become especially smooth and grippy, and under the weekend’s sun, it was warm and ready for MotoGP action. Make your guesses now as to whom was the King of the Brake Lever, and check your answers after the jump.

2011 Benelli TnT 1130 “Century Racer”

10/29/2010 @ 5:45 am, by Jensen Beeler7 COMMENTS

Founded in 1911, Benelli is celebrating its 100th year anniversary at EICMA this year with special “Century Racer” versions of its Tornado Naked Tre (TnT), the company’s naked three-cylinder street bike. The Benelli TnT 1130 “Century Racer” (a Benelli TnT 899 “Century Racer” is also being made available) features a desaturated green color scheme that honors Renzo Pasolini, and will be on display at the show in Milan. Along with the Century Racers, Benelli will have an exhibit that traces the company’s motorcycling history throughout its years. More details about the company’s 2011 model line after the jump.
