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.

MotoGP: Lap Time Analysis from De Puniet’s Suzuki Test

05/26/2013 @ 1:53 pm, by David Emmett12 COMMENTS

Suzuki-MotoGP-Racing-Prototype

Randy de Puniet has completed his first two-day test on Suzuki’s MotoGP machine. The Frenchman flew to Japan directly after the French round of MotoGP at Le Mans, to take part in the test organized at Motegi’s Twin Ring circuit, home of the Japanese round of MotoGP, and a circuit owned by Honda.

Under the terms of his testing contract, De Puniet is unable to say anything official, his manager Eric Mahé telling the French magazine Moto Journal only that the test “went well”. Suzuki did not publish any times from the test or provide any other information, but as the MotoGP test teams from both Yamaha and Honda were present, it was inevitable that times would leak out. German-language website Speedweek claims the scoop, with times also to be published in the Spanish magazine Motociclismo, which is out on Tuesday.

According to Speedweek, the test took place in excellent conditions, with temperatures of 28°C and a dry track. The German website reports De Puniet as having posted a time of 1’47.0 on Suzuki’s new inline four MotoGP machine, though no other confirmation of that time has been forthcoming. In comparison, that is as fast as Honda test rider Takumi Takahashi on the day, and half a second quicker than Yamaha test rider Katsuaki Nakasuga.

MotoGP: CRTs 14 MPH Slower Than Prototypes at Losail

04/06/2012 @ 9:40 am, by Jensen Beeler9 COMMENTS

Free Practice 2 for the Qatar GP has just finished at the Losail International Circuit, and the speed gap between the prototypes and the CRTs is abundantly clear. One of the faster tracks on the MotoGP calendar, everyone in the paddock knew going into the Qatar GP that the power advantage held by the Ducati, Honda, & Yamaha prototypes would be apparent down Losail’s .664 mile front straightaway. But now after getting to see how the two bike classifications stack up on the same course and on the same day, the results from FP1 & FP2 show a 13.6 mph gap between the tops CRTs to the top prototype GP bikes.

Colin Edwards Makes CRT Debut at Jerez

11/25/2011 @ 3:46 pm, by Jensen Beeler5 COMMENTS

Likely to be marked as the start of significant chapter in MotoGP history, the claiming rule teams (CRTs) were out in Jerez the past three days testing their MotoGP machinery, which is comprised of production-motorcycle motors with custom-built chassis. While not the first time we’ve seen a CRT bike on the track, the outing was the first time that  a”top-tier” rider was on-board the new racing format motorcycles, as Colin Edwards lead the charge with his BMW/Suter machine with NGM Forward Racing.

Many in the MotoGP paddock have been waiting to cast their verdict on the CRT endeavor, withholding their judgments until a top GP rider took to the helm of a CRT machine and properly put the bike through its paces. With tests earlier in the year showing Mika Kallio on-board the BMW/Suter to be over six seconds off the pace of the 800cc-era machines, the CRT future of MotoGP looked to be in jeopardy. Those lap times improved over the year to be “only” four seconds off that 1,000-era bike pace, showing improvement, yet a gap  to the front-runners.

Now with Edwards finally swinging a leg over the BMW S1000RR-powered Suter prototype, surely more comparisons between the factory prototypes and CRT offerings are to ensue. Posting a best lap time of 1’40.188 at the Spanish GP earlier this year, Edwards was roughly 2.5 seconds off his own pace, finishing the three-day test with a best lap to f 1’42.6. That news seems discouraging on its face, though it should be noted that the team dropped 1.3 seconds between Wednesday and Thursday’s tests.

Edwards also rated the bike at about 65% of its potential, while the Texan’s own fitness was questionable, as Edwards was till recovering from the injuries he sustained at the Malaysian GP. WIth all those caveat, does this week’s test equate to excuses for a lackluster performance, or justify that more leaps and gains will be made before the start of the 2012 MotoGP Championship?

04/11/2009 @ 12:20 am, by Jensen BeelerComments Off on Qatar Readies for the Return of MotoGP, Stoner Fastest Man on the Track

casey-stoner-free-practice-motogp-qatar

The return of MotoGP racing is just a few days away in Qatar right now, and Casey Stoner has proven himself the man to beat. Stoner was fast from the moment he rolled out onto the track, setting the 1’57 mark within 10 minutes of the free practice, a time he would reduce by a further 0.8 seconds towards the end of the session. Only two other men were able to break in’ the :57’s, Valentino Rossi and Colin Edwards. It took Rossi quite some time to catch the Australian, but he was eventually able to close the gap to Stoner by 0.4 seconds. Colin Edwards, the third fastest man in the opening session of the 2009 season finished 0.7 seconds off of Stoner. Outside of that group, Jorge Lorenzo made it 3 Yamaha’s in the top 4, but was still 1.2 seconds behind the time to beat.
