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.

Casey Stoner’s First Day Back at Ducati Was A Success

Casey-Stoner-Ducati-Corse-Sepang-Test-Ducati-Desmosedici-GP15-08

Casey Stoner got the first testing miles of his return to Ducati under his belt on Saturday. The Australian started slowly and steadily, doing a lot of short runs to get a feel for the Ducati Desmosedici GP15, on which he spent most of the day, before upping the pace later in the afternoon.

Journalists present at the test said Stoner looked a little stiff in his early laps, not getting either elbow or knee down, but soon started to relax, and look more like his old self.

He had every reason to be wary: the last time Stoner rode a race bike on the road was during the Suzuka 8 Hours, where a throttle cable malfunction saw him thrown from the bike, injuring his scapula and tibia in the process.

Furthermore, this was his first time on a MotoGP bike for a year, his first time riding the Ducati GP15 – a very different beast indeed to the GP10, the last Ducati Stoner raced – and his first time on the Michelins. Despite that, he told reporters he was very happy with how the test went.

Preview of the Catalan GP: The Showdown in Catalunya

06/10/2015 @ 7:09 pm, by David Emmett9 COMMENTS

Circuit-de-Catalunya-Aerial

From Mugello to Barcelona, or from the heart of Italian motorcycle racing to the heart of Spanish motorcycling. Or rather, Catalan motorcycling, as any of the many Catalans which fill the paddock will happily point out. Then again, Catalunya is – ironically – at the heart of Spanish motorcycling itself.

If MotoGP had a home race, it would be here. Series organizer Dorna has its offices just south of Barcelona, and the working language of the organization is Catalan. Just east of the circuit lies the old factory of Derbi, once a mainstay of the 125cc class.

Check the birthplaces of any one of the riders racing on a Spanish license, and most of them hail from one of the towns and villages within an hour or two’s drive of the Montmeló circuit.

Most riders still have a house in the area, though many elect to live in the tiny mountainous tax haven of Andorra, because of the opportunities it affords for training, so they tell us.

With so much support, can the Spaniards – or Catalans, or Mallorcans – lock out the podium at home? It would be a crowd pleaser for sure, but getting three Spanish riders to fill out the MotoGP podium at Barcelona will be far from easy.

That there will be one, perhaps two Spaniards on the box is a given. But filling all three places? That is going to be tough.

2015 MotoGP World Championship Preview

The prospect of a new MotoGP season always leaves fans giddy with anticipation. Their appetites keenly whetted by winter testing, and speculation over the times set at those tests, they boldly predict that this season is going to be the best MotoGP season ever. Though the racing is often good, all too often, it never quite lives up to the preseason hype.

There is every reason to believe that this year, it will be different. The bikes, the riders, the teams, the motivation, it all points to 2015 being an exceptionally exciting season in MotoGP.

At the last day of winter testing at Qatar just over a week ago, less than a second covered the top fourteen riders, and two seconds covered all but four of the MotoGP field.

A similar pattern emerged at Sepang: with the exception of the occasional hot lap by Marc Márquez, there were ten or more riders within a second of each other. Things haven’t been this close for a while.

MotoGP Qatar Test Summary – Day 2: The GP15 Is for Real, The Rest of the Field is Close

03/16/2015 @ 1:20 am, by David Emmett24 COMMENTS

There are some worried faces in the MotoGP paddock after the second day of the Qatar test. That the Ducati GP15s are fast should come as no surprise, after all, they were fastest on the first day as well.

The trouble is that everyone assumed that the speed of Andrea Dovizioso and Andrea Iannone was down to the fact that they can use the soft tire, which is not available to Honda and Yamaha.

Despite the protestations of the two Ducati riders, who had said they spent all day on the medium tire, the same tire which the Hondas and Yamahas had used, Valentino Rossi, among others, had cast aspersions on their claims, suggesting that their fastest laps had been set on the soft tire.

They weren’t. Ducati’s official press release stated explicitly that the two Andreas had not gone anywhere near the soft tire so far, concentrating on improving the GP15 on the medium tire, the tire they will race.

Ducati’s press officer confirmed this explicitly to the Bikesportnews website. And just to check, I trawled through all the photos I could find of the factory Ducati team: through the official Ducati press website, through the official MotoGP.com website, and through a couple of other media sites. Not a single photo did I find of a tire with a white stripe, the sign of the soft tire. They really did use the medium tire.

MotoGP Qatar Test Summary – Day 1: Did Ducati Really Use the Softer Tire to Dominate?

03/15/2015 @ 1:46 pm, by David Emmett20 COMMENTS

dovizioso-iannone-qatar-test-ducati-corse

Did they or didn’t they? That was the question after Ducati dominated the first day of the test at Sepang. Andrea Iannone and Andrea Dovizioso spent all day swapping places at the top of the timesheets, Iannone coming out on top at the end.

It was an impressive showing, but MotoGP watchers and Ducati’s rivals were quick to pass judgment: of course the Ducatis were fast, after all, they were allowed to use the soft rear tire, a concession for the Open class teams and factories who have yet to win three races in the dry. That tire is worth six or seven tenths a lap, said Valentino Rossi.

Only they didn’t use the soft tire. At least, that is what Andrea Dovizioso told reporters. He spent all day working on race setup, first on the GP14.3 to set a baseline, and then on the GP15 to work on braking set up and electronics.

MotoGP Sepang 2 Test Summary – Day 3: Honda vs. Yamaha & Why the Open Honda Is Still Slow

02/25/2015 @ 9:39 pm, by David Emmett8 COMMENTS

jorge-lorenzo-sepang-test-motogp-yamaha-racing

Take a glance at the timesheet after the final day and it is easy to draw some simple conclusions from of second Sepang MotoGP test. Marc Márquez reigns supreme, with Jorge Lorenzo is the only rider to get anywhere near to him.

Cal Crutchlow has improved, but at the moment is only fast over a single lap. The Ducati Desmosedici GP15 is fast, but only in the hands of Andrea Iannone. Valentino Rossi and Dani Pedrosa have their work cut out if they are to match their teammates.

Bradley Smith has surpassed his teammate, Pol Espargaro. Suzuki is close, but not quite close enough, while Aprilia is hopelessly lost.

As attractive as those conclusions are, the underlying truth is a lot more complex. Testing is exactly that, testing, and everyone is on different programs, trying different things at different times of the day.

Or as Dani Pedrosa succinctly put it, when asked if he was trying out a new strategy for qualifying during the test, “we were just trying. That’s why we are here.”

MotoGP Sepang 2 Test Summary – Day 2: Marquez vs. Lorenzo, Thumb Brakes, & Melandri’s Fall

02/24/2015 @ 3:12 pm, by David Emmett14 COMMENTS

marc-marquez-sepang-2-test-HRC

After the excitement and confusion of the first day of testing at Sepang, some semblance of normality returned on Tuesday.

Cooler temperatures and more stable weather meant that riders had much more time to do work on track, the heat and humidity not quite as oppressive as they had been the previous day. The excitement over new bikes and gearboxes had also subsided, and the hard grind continued.

If Tuesday is representative of the normal state of play in MotoGP, then it seems like there are already two favorites for the title emerging from the pack, though margins are slim indeed.

Marc Márquez and Jorge Lorenzo were the only two riders to crack the two minute barrier, posting fast times early-on in the day, then getting back to work on 2015.

Nobody else got near, with the exception of Andrea Iannone, who piled in a quick lap at the end of the day to fall just short of two minutes, the Ducati GP15 quickly proving its worth.

MotoGP Sepang 2 Test Summary – Day 1: Hard Work, Heavy Weather, & New Bikes

andrea-dovizioso-ducati-gp15-sepang

If the purpose of testing in Sepang is to ensure that as little time as possible is lost to the weather, then the first day of the MotoGP test fell well short of its objectives. The Malaysian circuit sweltered under oppressive tropical heat all day, rendering most of the day of little use for testing.

With track temperatures approaching 60°C in the early afternoon, the grip disappeared, and the heat made riding a MotoGP bike a punishing affair.

Then, just as the riders returned to the track as the air began to cool, a tropical thunderstorm washed the track out, with lightning causing the session to be red-flagged for a while. It was not a day in which the teams could get an awful lot done.

That was a shame, as they had an awful lot to do. Ducati had brought the GP15 for its on-track debut, Yamaha had its fully seamless gearbox, Suzuki had unleashed a few more horses from its GSX-RR, and Aprilia had a stack of chassis and electronics solutions to test on track. With on a couple of hours of productive track time, much was left untested.

2015 MotoGP Sepang 2 Test Preview – Seamless Gearboxes, Brand New Ducatis, & Fast French Rubber

Saturday-Sepang-MotoGP-Malaysian-Grand-Prix-Tony-Goldsmith-5

The engineers have had two weeks to pore over the data from the first MotoGP test at Sepang, identify problems, analyze strengths, and find more ways to go faster. Their analyses have been translated into designs, into new parts, into yet more software, ready to put their theories into practice.

On Monday morning, at 10am Malaysian time, the MotoGP riders get to try out all of the new parts and ideas thought up by their factories and teams in search of a few more fractions of a second.

The eyes of the world will not be on what the engineers did between Sepang 1 and Sepang 2, however. Attention will be focused on Yamaha and Ducati, who will be testing hardware which has been a long time coming.

Yamaha is bringing its fully seamless gearbox to the Sepang 2 test, and Ducati will roll out its Desmosedici GP15 for the first time. Both could make a significant impact.

Analyzing The Ducati Desmosedici GP15

02/17/2015 @ 8:55 pm, by David Emmett10 COMMENTS

2015-Ducati-Desmosedici-GP15-MotoGP-Andrea-Dovizioso-16

Anyone watching the presentation of Ducati’s 2015 MotoGP bike will have learned two Italian phrases: “Emozionante” and “tanto lavoro”. Both were extremely apt.

Getting from where Ducati was to where it is now with the Desmosedici GP15 had needed “tanto lavoro”, a lot of hard work, and they still have “tanto lavoro” ahead of them.

The results were “emozionante”, a fantastic word nearer to exciting than emotional. But both exciting and emotional were apt phrases. The sense of eagerness was palpable among Ducati staff at Bologna on Monday. For good reason, the GP15 presented in a long, loud, and rather meandering show is radically different from what came before.
