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.

Saturday MotoGP Summary at Austin: Explaining Crashes, And New Rivalries

04/23/2017 @ 11:03 am, by David EmmettComments Off on Saturday MotoGP Summary at Austin: Explaining Crashes, And New Rivalries

There is a move afoot among MotoGP riders to have qualifying changed. Or rather, to have the way the selection is done for Q1 and Q2. A lot of riders have complained about the current system of prequalifying using combined times from FP1 through FP3.

The riders complain that they lose too much time to trying to set a fast lap in each session, just in case conditions change. The current counter proposal from the riders is to use just the FP3 times to select which riders go through to Q2 directly, and allow the teams to spend Friday focusing on setup.

Saturday morning exposed the weakness of such an idea. A combination of cold tires, strong wind, a bumpy track, poor tire selection on Friday night, and the narrow temperature working range of the Michelins saw eight riders crash a total of ten times in FP3.

Alex Rins crashed so heavily he broke both the radius and ulna in his left arm, and put himself out of action for Austin and Jerez, and possibly for Le Mans as well. The rest escaped relatively unscathed, but with many a temper blazing.

Basing passage into Q2 solely on FP3 results was not without risks of its own, Valentino Rossi told the Italian media. “Today, that would have been a stupid idea, because we would have had to take a lot of risks in difficult conditions,” Rossi said.

If there had been a total of ten crashes in a session in which most riders hadn’t pushed to improve their time, how many would have fallen if they had all been pushing to get through to Q2?

Friday MotoGP Summary at Austin: Honda’s Real Weakness

04/22/2017 @ 10:03 am, by David Emmett4 COMMENTS

It looks like we have been wrong all along. As usual. All this time, we thought it was the engine which was the problem for Honda.

This would be a major issue, as engine designs are sealed and fixed for an entire season in MotoGP, at least for factories which have gathered sufficient podium credits to qualify as competitive under the rules. With nine wins last year, and a MotoGP title, Honda definitely does that.

Maybe the problem isn’t the engine after all, however.

Honda riders are starting to express the apparently unpopular opinion inside HRC that maybe the solution isn’t to rejig the engine again by playing around with firing orders, crankshaft counterweights, and other internal moving parts now set in aspic until the season ends at Valencia.

Perhaps, they suggest, Honda could take a look at its chassis, and try finding solutions there.

Cal Crutchlow was the most vociferous, though that is an extremely relative term when speaking of rider statements about the Japanese manufacturer they ride for. “I think we need to start working with the chassis a bit more,” Crutchlow told us after another hard day at a very physical track.

“That’s not a comment against my manufacturer, against my team, it’s just a comment that we’ve looked at the engine for the last two years, and I believe that a lot will come from the chassis. Sure, some electronics, but I think it’s chassis. I’ve ridden other bikes, so I know what the chassis is doing. And I believe that’s where we could improve a lot. Because the engine is sealed, that’s done, it’s done and dusted.”

Kenny Roberts Jr. Named a MotoGP Legend

04/21/2017 @ 9:48 pm, by Jensen Beeler1 COMMENT

The list of MotoGP Legends is constantly growing with some of the best names ever to ride a motorcycle, and now one more can be added to the list: Kenny Roberts Jr.

The 500cc World Champion in 2000, Kenny Roberts Jr. broke the streak of premier class wins by Honda, with his Suzuki – the victory also making him part of the first father-son duo to win 500GP Championships.

Thursday MotoGP Summary at Austin: The Bad New Days, And Talk of Tires

04/21/2017 @ 10:18 am, by David Emmett5 COMMENTS

If you wanted proof that MotoGP fans are smarter and more engaged than most people think (and arguably smarter, more engaged, and better informed than half the journalists in the paddock), then look no further than the section added to the press conference by Dorna featuring questions submitted by fans via Social Media.

The questions submitted so far have been funny, interesting, and thoughtful (though of course, it helps that the hardworking Dorna Social Media staff carefully separate the wheat from the chaff beforehand).

They have managed to be revealing, coming at riders from unsuspecting angles and forcing them to let slip things without realizing it.

Or sometimes, it just gets them talking in a broader context, which helps provide a greater insight into the way the sport has changed, and the direction it is heading. And sometimes, they have just made us all laugh.

The question to Valentino Rossi, asking which of his rivalries should be made into a movie to match Rush, the dramatization of the rivalry between James Hunt Niki Lauda.

There is no obvious answer to that question – Rossi’s rivalries have been many, fierce, and bitter, with Casey Stoner, Jorge Lorenzo, Marc Márquez, Sete Gibernau – but Rossi settled on his rivalry with Max Biaggi. “It was funny, because we also had a lot of funny stories out of the track,” Rossi quipped.

MotoGP Preview of the Americas GP

04/20/2017 @ 2:13 pm, by David Emmett2 COMMENTS

The most remarkable statistic about the Grand Prix of The Americas is surely this: Since his ascent to the MotoGP class, Marc Márquez has won every single race he has competed in, at a circuit in the United States of America.

He won both US races during his two years in Moto2 as well. In fact, you have to go back to 2010, and Márquez’s final year in 125s to find the reigning world champion’s last defeat on US soil. America agrees with Marc Márquez, though that does not automatically include all Americans as well.

So after a decidedly mediocre start to his defense of the 2016 MotoGP title, the Circuit of The Americas in Austin, Texas is the right place to get his season back on track. He comes to COTA knowing he can win, and knowing he can win on an uncompetitive machine.

That knowledge alone will be worth a tenth or two in Austin, perhaps enough to give him the edge over the all-conquering hero of the hour Maverick Viñales.

Why does COTA suit Márquez so well? It is really hard to say. Perhaps because it offers so many opportunities to make up time on the brakes. First, there’s the uphill monster of Turn 1, perhaps the weirdest first corner of the season (fittingly keeping Austin weird).

Then there’s Turn 11, the hard, sharp hairpin before the long back straight, at the end of which there is Turn 12, another spot requiring hard braking. And at the end of the lap, the two final corners, Turn 19 and Turn 20, which are shorter, but just as fierce.

Perhaps it’s not so much the braking, but more the strange section of combination corners stretching between Turn 2 and Turn 10. They are the kind of corners that reward the ability to turn on a dime, and the all-front-end, all-the-time Honda deals well with those.

Or perhaps the corners through the Stadium Section, and around the Grand Plaza.

2017 MotoAmerica Provisional Calendar Released

10/07/2016 @ 1:19 pm, by Jensen Beeler5 COMMENTS

motoamerica-logo

The provisional calendar for the MotoAmerica AMA/FIM North American Road Race Championship has been released, and it features a 10-stop tour for American road racing.

The 2017 calendar looks like an improvement over the 2016 schedule, with fewer gaps between races and no repeat venues. Fans will also welcome the return of Sonoma Raceway (that’s Sears Point to you locals) to the calendar, as well as the debut of Pittsburgh International Race Complex (one of my personal favorite tracks).

Geographically, the 2017 MotoAmerica calendar makes a lot more sense too, with more of a logical progression across the map between races, a benefit for teams and logistics personnel.

Fans from around the USA should be able to get to at least one round within a day’s travel by car, which should help attendance numbers.
