Beauty Is Wedging an RZ350 Motor into an RS250 Frame

I am about to ruin your day, because I am going to show you something that you will want very badly, but can’t have. It is what happens when you have the best of both worlds. It is the two-wheeled version of having your cake and eating it too. This machine is called the Yamaprilia, and as the name implies, it is a mashup of the Yamaha RZ350 and the Aprilia RS250. Using the two-stroke, twin-cylinder engine from the RZ350, and the twin-spar aluminum chassis of the RS250, owner Gareth Evans is looking for the best of both worlds. The build is an interesting one – and is featured by our friends at BikeEXIF – as it involves Evans fabricating more than a few parts himself – something that is easier to do when you have a background in mechanical engineering, like Evans does.

The Ducati Panigale R and Its Carbon “Wheel Cover”

While everyone else seems to be turning a blind eye to aerodynamics, Ducati continues to be the brand pushing the aero envelope with its designs. As such, World Superbike fans may have seen this weekend that Chaz Davies was sporting a unique rear end, as Ducati Corse continues to experiment with a lenticular wheel setup. A piece of technology borrowed mostly from cycling, the carbon fiber disc “wheel cover” provides a more slippery surface for the wind to flow over, than the chaos that comes from a spinning spoked wheel on a motorcycle. Ducati has played with a lenticular wheel before, with Michele Pirro sporting the design in the recent MotoGP testing season.

Pirelli Responds to WorldSBK Tire Woes with Change

The Misano round of WorldSBK was dominated by talk of tires. As such, following a weekend fraught with failures, Pirelli will revert to an older specification of tire for the Laguna Seca round. The move sees Pirelli at a crossroads, after a series of high profile incidents during the scorching weekend in Italy. This includes Michael van der Mark’s crash from the lead of Saturday’s race, after a tire failure saw the Dutch rider robbed of his chance to claim his first podium for Yamaha. One has to remember too, Jonathan Rea also crashed out of the lead at the previous round in Donington Park, as it was a shock to see the previously robust Pirelli fail once again.

Oh My, The “Miracle Mike” Is One Tasty Indian Scout Build

That’s it. Hell must be freezing over, as I just had to mop up the floor after looking at photos of a cruiser. What you see here is called the “Miracle Mike” and it is the creation of the minds at Young Guns Speed Shop. The bike is built off the Indian Scout, an affordable entry-level cruiser that boasts pretty good performance for its $10,000 price tag, but is generally a pass for anyone that likes leaning more than 31°. Here at Asphalt & Rubber, we’ve had a bit of time on both the Scout and its sibling, the Victory Octane, and found the models to be potent, but in need of a better gearbox and front brakes…and a serious diet wouldn’t hurt too. The Swiss minds at Young Guns seemed to think the same, making smart improvements to the Indian Scout for their creation. And heck, a little nitrous “go juice” never hurts, right?

In Search of the Ultimate Motorcycle Paddock Stand…

Here is something interesting that popped up in my social media feed recently (see, online maketing does work!), which I thought was worthy of sharing with Asphalt & Rubber readers, as I am in search of the ultimate set of paddock stands for my fleet of motorcycles. Dynamoto is a new brand name in the age-old paddock stand business. It is rare to see new things in this space, but the folks at Dynamoto seem to have an interesting concept, as its a bike lift that can move freely around the garage with the bike still on it, using a novel dual-axis wheel design. If your garage is as choked full with motorcycles as mine is, being able to move a bike easily, especially on a service stand, is a valuable ability to have. Dynamoto seems to have this very need in its mind with its clever design, though their design does have its flaws.

2018 Yamaha YZ450F Debuts with Tuner App

Not one to let the other brands have all the fun, Yamaha has debuted its all new 450cc class motocross bike, the 2018 Yamaha YZ450F, which features the first engine tuning app available for a production MX bike. The new Yamaha YZ450F is truly an all-new machine, with a new engine, frame, and bodywork. For bonus points too, the new YZ450F comes with an electric starter, which means MX riders can now skip leg day at the gym, and still get their bikes running on race day. Available in July, in either “Team Yamaha Blue” or “White” color schemes, the 2018 Yamaha YZ450F will cost $9,199 MSRP. This price includes the onboard communication control unit (CCU), which allows the rider to connect to the bike via smartphone.

Pikes Peak Gets EMT Motorcycles from Ducati

The Pikes Peak International Hill Climb is rapidly approaching, and the iconic “Race to the Clouds” continues to mature, despite this year being its 95th running. Helping mitigate the safety issues that come with racing on the mountain’s 156 turns is Ducati North America, which already supports racer mentoring with the Squadra Alpina program. Now, Pikes Peak is taking another step forward. Again with the help of Ducati North America, the Pikes Peak International Hill Climb will have emergency first-responders on motorcycles. This is a page taken straight out of the Isle of Man TT, where traveling marshals move by sport bike between checkpoints, and are often the first medical personnel on the scene of a crash.

More Photos and Details of the MV Agusta RVS #1

Yesterday we showed you the MV Agusta RVS #1, the first creation from the Italian marque’s Reparto Veicoli Speciali program, which is making limited run machines out of MV Agusta models. Reparto Veicoli Speciali comes straight out of the Castiglioni Research Center, MV Agusta’s design studio, and this division will focus solely on making dedicated bikes for special customers. One bike, one customer, is the premise. The RVS #1 might bear familiar lines to the MV Agusta Brutale 800, but this machine is hand-built and features the most powerful three-cylinder engine in MV Agusta’s lineup, with 150 hp coming from the 350 lbs (and Euro IV compliant) machine.

The Updated 2018 Husqvarna FS 450 Supermoto Debuts

Husqvarna continues to be the only motorcycle manufacturer with a race-ready supermoto, straight from the factory, and what a machine it is, the Husqvarna FS 450. For the 2018 model year, the Swedish brand has added more updates for the Husqvarna FS 450, keeping it at the pointy end of technology. The big changes come in the form of a new slipper clutch from Suter, and brand that any MotoGP team should be familiar with, along with a new map switch control on the handlebar, which continues to toggle on and off the bike’s traction control, dual engine maps, and launch control features. The last change of note for the 2018 model year that Husqvarna wants us to share is that fact that there is a new graphics package…this year, the seat is blue.

MV Agusta Debuts Its First “RVS” Motorcycle Concept

The intrigue is finally over in regards to MV Agusta’s new “Reparto Veicoli Speciali” or “RVS” program, with the Italian marque debuting its first creation from this special vehicle development unit. An intersection between the designers and engineers at MV Agusta’s Castiglioni Research Centre, RVS is what happens when you let designers be free with their imaginations, and you let engineers create those ideas unfettered – at least, so says MV Agusta. The result for this fist iteration is a very unique looking MV Agusta Brutale 800, which has a bevy of custom pieces on it that make it look like a café racer / scrambler type of machine.

Bits & Bobs: Racing News Post-Argentina GP

04/11/2017 @ 9:59 am, by David Emmett8 COMMENTS

Along with a thrilling weekend of racing, several interesting items of news emerged in Argentina. Brad Binder and Remy Gardner were injured, and face surgery.

Also, discussions were held in the Safety Commission regarding who progresses to Q1 and Q2. And at a press conference, Dorna announced that the WorldSBK championship will be racing in Argentina in 2018, at a new circuit in the west of the country.

Saturday MotoGP Summary at Argentina: Wild Weather, The Wizard of the Wet, & The Great Tire Conspiracy

04/09/2017 @ 11:20 am, by David Emmett3 COMMENTS

MotoGP’s weird and wonderful Argentina trip continues to confuse, with qualifying turning out as topsy turvy as ever. Or perhaps not quite as topsy turvy as yesterday: though the front of the MotoGP grid still contains more than a couple of surprise names (more on that later), there are the first signs that some semblance of normality is starting to creep back. 

That doesn’t mean it’s going to be 2009 again any time soon, when the grid basically predicted the finishing order, bar accidents, but bookies everywhere are worrying less about the chance of a rank outsider staging an upset. On Friday, all bets were off. On Saturday, they were hedging their bets again.

Oddly enough, part of that was down to the weather. It was a peculiar day in terms of weather, the morning starting cool and dry, but rain starting to fall at the end of MotoGP FP3. 

It dried out again after that, allowing Moto3 to start their qualifying session on a dry track, before the rain returned with a few minutes to go. MotoGP FP4 took place on a wet track, but the rain lifted and the track started to dry during qualifying. Q1 was wetter than Q2, and tire choice became crucial. Vacillating between the soft and the hard tires cost more than one rider passage through to Q2.

By the time Moto2 took to the track, a dry line was starting to form. Andrea Iannone had gambled on going out on slicks during Q2 but came straight back into the pits when it turned out to be impossible. 

The Moto2 riders went out on wet tires at first, but were quickly able to switch to slicks. With the track improving with every lap the riders put in, pole position was changing hands just about every time a rider crossed the line. In the last 22 minutes of qualifying, the pole time was slashed by eight and a half seconds.

FIM Releases Report Analyzing Luis Salom’s Crash

07/22/2016 @ 9:48 am, by David EmmettComments Off on FIM Releases Report Analyzing Luis Salom’s Crash

luis-salom-portrait

The FIM have published a report into the crash in Barcelona, in which Moto2 rider Luis Salom lost his life.

The report, which can downloaded from the MotoGP.com website, was drawn up based on information from Technical Director Danny Aldridge and Director of Technology Corrado Cecchinelli, as well as analysis of the data by an independent telemetry expert, Lluis Lleonart Gomez, who was appointed by Luis Salom’s family.

The report reaches a number of conclusions. The first is that there is no evidence of mechanical failure on the part of the bike. The right clipon, holding the throttle and brake assembly, was found to be loose when the bike was examined after the crash.

However, this could be put down to crash damage, as clipons often come loose when the bike hits the ground. Salom’s bike slid on its right side before impacting the wall, and this is the most likely cause of that damage.

The rear wheel was also damaged, but data from the (compulsory) pressure sensors showed that rear tire pressure was at the recommended pressure of 1.5 bar when the bike crashed.

The most likely cause of the rear wheel damage was when the bike hit the wall, the air fence not being sufficient to absorb the impact of the bike.

Friday MotoGP Summary at Sachsenring: Turn 11 Again, Replacing the Sachsenring, & Marc vs. Maverick

07/15/2016 @ 10:12 pm, by David Emmett1 COMMENT

Friday-MotoGP-Sachsenring-German-GP-Cormac-Ryan-Meenan-22

It was a wasted day at the Sachsenring. The day started cold but with a dry track, then, ten minutes into MotoGP FP1, a fine mist of rain started to fall, making already tricky conditions positively terrifying.

A few journalists walked through the Sachsenring paddock up towards the end of pit lane, where the fences give you great views of Turn 1 and Turn 11.

Just as we arrived, Scott Redding’s battered Pramac Ducati returned to the paddock in the back of a recovery trailer. When we turned around to watch the bikes coming through Turn 11 again, Jorge Lorenzo slid through the gravel towards us, his foot caught up in his bike for a while.

While we were watching Lorenzo hit the gravel, we heard another bike scrape across asphalt and into the gravel. It was Stefan Bradl’s Aprilia, the German having lost the front at Turn 11, just as Lorenzo had.

The rain continued, never really heavy enough to soak the track properly, only lifting towards the end. A few riders went out on wet tires to check their repaired bikes, coming straight back in again.

The morning session was lost to the weather conditions. The afternoon session was a little better – at least it was dry – but the track temperatures meant that the tires never really got to the operating range they were designed for.

Friday MotoGP Summary at Assen: On Weather, Deceptive Race Pace, And Rules & Regulations

06/25/2016 @ 12:06 am, by David Emmett3 COMMENTS

MotoGP-2016-Assen-Rnd-08-Tony-Goldsmith-1664

The disadvantage of reporting on your home race is that during the media debriefs, the period when riders speak to the press, they turn to you and ask, “So what’s the weather going to do?”

Living in The Netherlands, Assen is my home race, and so this weekend, it is me they are asking about the weather. There is only one honest answer I can give them. “This is Assen. Anything can happen.”

The weather has been a constant topic of discussion. Weather apps and weather websites have been compared, and each of them says something different. Some say it will only rain heavily on Sunday. Others say Sunday will be dry, and the rain will fall on Saturday.

Check another site, and it says rain overnight, but only heavy clouds during the day, with the risk of rain at a minimum. Which site to believe? This is Assen. Anything can happen.

There was a sense of nervousness in both FP1 and FP2 for the MotoGP class. Riders pushed late to chase a lap good enough to put them into the top ten, and automatic entry into Q2.

Some, like Bradley Smith, got their strategy wrong, went out on a hard rear tire instead of a medium, and ended up languishing down the order. Others, like Dani Pedrosa, were just having a dismal time. “No improvement from FP1 to FP2, no improvement on different tires, and no feeling with the bike.”

Saturday MotoGP Summary at Catalunya: Dealing with Danger, Data-Driven Design, & the Right to Complain

06/05/2016 @ 1:01 am, by David Emmett8 COMMENTS

Saturday-Catalan-GP-MotoGP-photos-Cormac-Ryan-Meenan-27

What does the MotoGP paddock do the day after a rider dies? Carry on as normal. Or nearly normal: bikes circulate, riders compete, but conversations are more hushed, the mood muted. The whole paddock is a quieter place, bar the bellowing of racing four-stroke engines.

Heartless? That is putting it a little strongly. It is in part a coping mechanism, immersing yourself in your work to avoid dwelling on tragedy, and thinking too much about danger.

But it is also a response to the request of Luis Salom’s family and team. When Dorna boss Carmelo Ezpeleta asked them what they wanted to do, they said they wanted the race to go ahead.

Their wishes would be respected, but it was not the first choice of everyone in the paddock. Danilo Petrucci told the Italian press he would have preferred to have packed up and gone home, and he was not alone.

“Yesterday I was crying together with my brother because [Luis Salom] was really young,” Aleix Espargaro told us. “This is a disaster. With Pol we were thinking that the best thing was to not race because actually now I feel empty inside.” We all felt empty inside, and still do.

Moto2 & MotoGP Races Shortened Because of Tire Concerns

10/19/2013 @ 3:53 am, by David Emmett11 COMMENTS

Saturday-Phillip-Island-MotoGP-2013-Scott-Jones-13

The lack of tire testing prior to the Phillip Island round has caught both control tire companies out. As such, Race Direction has decided to shorten the Moto2 race from 25 to just 13 laps, while the MotoGP race will now include a compulsory pit stop to swap bikes, and the race length has been cut by one lap from 27 to 26 laps.

In addition, the MotoGP riders are prohibited from using the softer option rear tire, and will be forced to use the harder option. Both decisions were taken on safety grounds, after it was found that neither the Moto2-spec Dunlop nor the MotoGP-spec Bridgestone can handle race distance on the newly-resurfaced tarmac.

The lighter, less powerful Moto3 bike are not affected, and the Moto3 race will run the scheduled length.

MotoGP: About Bridgestone’s Tire Failures at Assen

07/09/2012 @ 7:03 pm, by David Emmett8 COMMENTS

The tire problems experienced by Valentino Rossi and Ben Spies at Assen, where great chunks of rubber came off the right side of the rear of the tire, slowing Spies up severely and affecting Rossi so badly he was forced to pit for a new tire, have been the subject of much speculation and discussion since the event. Spies was particularly shaken after the race, the tire problems bringing back bad memories of the 300 km/h tire failure and monster crash he had at Daytona back in 2003, which he still has the scars to show from.

Nearly a week on, and after examination by Bridgestone technicians back at the factory in Japan, we can start to draw a few preliminary conclusions as to the cause of the problems. Bridgestone have issued a press release and briefed the press directly, and the riders have weighed in with their thoughts and impressions of what happened. Before pointing fingers and apportioning blame, let us first walk through what we know of what actually happened.

Dorna Blinks – Australian GP to Remain in October

03/19/2011 @ 3:30 pm, by Jensen Beeler3 COMMENTS

Dorna and Phillip Island have been embroiled in a debate over moving the Australian GP to an earlier venue — a subject that seems to come up every time the premier series comes to the fabled island circuit. After Phillip Island rebuked the idea of moving its date for the MotoGP Championship, choosing to instead balance the race later in the calendar against other major events that come to Oz, namely Formula 1 (March 27th) and World Superbike (February 27th).

Not one to take rejection lightly, Dorna put Phillip Island on notice, suggesting that while the two parties did have a contract that saw the race pegged to the month of October, that agreement was only valid if Phillip Island kept its FIM homologation. This statement presumably suggested that Dorna would influence the FIM to remove accreditation for PI to run MotoGP events, should the Australians hold their ground. With neither party budging, serious concern began to grow over the Australian track.

With the MotoGP Safety Commission meeting today in Qatar, the issue of moving the Australian GP was broached and decided upon, with the Commission choosing to keep MotoGP’s stop in Phillip Island during the month of October. Glad to see his home race intact, Casey Stoner still had some thoughts on the issues surrounding the Australian GP date. Click after the jump to see his thoughts.

World Superbike Riders Forming Safety Commission

02/25/2011 @ 10:13 am, by Victoria Reid4 COMMENTS

World Superbike riders have begun establishing a safety commission to have a stronger voice in providing safer conditions for racers in the series. Though other top-tier racing series have long had a body specifically to promote the safety of riders and drivers, it seems that the timing of the race at Donington Park this season has moved the riders to join forces. They met first during the official test in Portimao a month ago and met again this week during the testing at Phillip Island.
