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.

Sunday MotoGP Summary at Austin: Leaders Crashing, And Rossi vs. Zarco

04/24/2017 @ 5:45 am, by David Emmett21 COMMENTS

When riders get off to a blinding start in the first couple of races, it is easy to get carried away and start penciling their name onto the championship trophy. Doing that after just two races is plainly ridiculous.

Doing it after three races is hardly any better. Yet the temptation to do so remains strong: when a narrative presents itself, it is hard to resist following it.

That has been the case so far this year. In Moto3, Joan Mir has looked untouchable winning the first two races from tough fights. In Moto2, Franco Morbidelli had dominated, controlling races from start to finish.

And coming into Austin, Maverick Viñales had won the first two races of the season quite comfortably, nobody anywhere close to being able to match him.

During practice, a new narrative presented itself in MotoGP. Marc Márquez has dominated the racing at the Circuit of The Americas since it first joined the calendar, winning all four races held there before this year.

Maverick Viñales has dominated the opening two races of the year, and came to Austin looking capable of ending Márquez’ winning streak.

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.”

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.

MotoGP Phillip Island MotoGP Test Summary – Day 2

02/16/2017 @ 11:30 pm, by David Emmett7 COMMENTS

Scouring through the timesheets after the second day of the MotoGP test at Phillip Island, and reading through everything the riders have said, a picture emerges, not just of what happened on Thursday, but also how history has affected them.

Seeing Marc Márquez’s workload, his approach, the things he is working on, and it is hard not to think back to his past three seasons in MotoGP. The lessons learned in each of those seasons color everything he is working at Phillip Island, and give us a glimpse of his objective for 2017.

On Thursday, Márquez put in 107 laps around Phillip Island. That is 20% more than most of his rivals, and nearly double the amount that some of them rode.

Asked if he was playing games in suggesting the 2017 Honda RC213V was not ready, Márquez was curt. “I don’t play games, because if I’m ready I would not make 107 laps! Because my hands are destroyed.”

Why put in so many laps? A look at the past three seasons offers an insight. In 2014, Márquez destroyed the field in the first part of the season, winning ten races in a row, and a total of thirteen.

For a man with a thirst for victory matched perhaps only by Valentino Rossi, this was an ecstatic period. It also lured him into a false sense of security, the bike suffering as a result. This was not helped by Honda’s insistence on building a bike as powerful as possible, with no view of making it easy to use.

2015 was a watershed year for Márquez. He crashed out of so many races trying to win them that he threw away any chance of defending his title. He put the lessons learned into 2016, and won the title last year by learning to settle for points.

Sometimes, after the race, you could see from the expression on his face that not winning races had caused him something approaching physical pain.

MotoGP Phillip Island MotoGP Test Summary – Day 1

02/15/2017 @ 4:57 pm, by David Emmett11 COMMENTS

There’s this thing called sandbagging in motorcycle racing. You’ve probably heard about it. It’s where a rider doesn’t show his hand completely ahead of the season, doesn’t smile in public, hangs a tale of woe on the media, about how he is struggling with the bike, and how much work they have to do.

Then, when the flag drops and the racing starts for real, the rider goes out and completely destroys the opposition.

The key to sandbagging is not to give too much away on the timesheets. Riders find all sorts of smart ways of doing this. Working on one sector at a time, perhaps. Pushing for the first half of the lap, then backing off for the second half.

On the next run, they back off in the second half of the lap, and push for the second half. The bare lap time shows up as unimpressive, but put the two halves together and you have something very impressive indeed.

Marc Márquez appears to be trying to sandbag at Phillip Island, but he is not doing a very good job of it.

He has the act down just fine: lots of criticism of the bike, a lot of concerns about which areas still need work, pointing out that Phillip Island tends to hide the weak point of the Honda RC213V. The point where he is falling down on is hiding it out on track.

Check Out the 2017 Honda RC213V

02/03/2017 @ 4:10 pm, by Jensen Beeler28 COMMENTS

The MotoGP launch season is still upon us, and now that we have seen the teams and bikes from Ducati, Suzuki, and Yamaha – it is time for Honda to take the wraps off the team its campaigning for its title defense.

Debuting the 2017 Honda RC213V at a press event in Indonesia, not much has changed outwardly for the 240+ horsepower GP bike, though there a subtle differences to be seen, if you look closely and compare it to last year’s bike.

The Repsol Honda fairings cover the biggest change that we know of, as reports from the test tracks confirm that Honda is experimenting with a “big-bang like” firing order on its V4 engine, a change from the “screamer” configuration of last season, which was handful for Marc Marquez and Dani Pedrosa to manage.

2017 Sepang MotoGP Test Preview

01/30/2017 @ 1:39 am, by David Emmett1 COMMENT

In a few hours time, the grandstands at the Sepang International Circuit will echo with the booming assault of MotoGP machines being pushed to their limits. The entire MotoGP grid has assembled for the first test of the preseason, meaning that the 2017 MotoGP season is about to get underway, at last.

That, at least, is the plan. The reality is that the grandstands may echo only to the sporadic rasp of a MotoGP bike being warmed up, and the occasional intrepid test rider being sent out to test conditions.

The resurfaced Sepang continues to be plagued by drainage problems, water remaining on the track for a long time. In high humidity, relatively low track temperatures and without the burning tropical sun, the water left by unusually heavy rains is not evaporating.

Parts of the track remain wet all day, making it impossible to push the bikes to the limit, and very risky to try.

Suzuki team boss Davide Brivio expressed the concerns shared by most teams.

“You never know how many hours you can test, because the track remains wet for a long time. And if it rains a lot in the evening, maybe you have to wait a long time in the morning. So it’s a little bit of a question mark now, how much you can test.”

Wednesday Summary at the Valencia MotoGP Test

2017-valencia-test-jorge-lorenzo-track

So 2016 is officially at an end, and the first test of 2017 is in the books. By the end of what is essentially a week of hard work, the entire paddock – riders, mechanics, journalists – are completely exhausted, and tired of it all.

The frisson of the first test of 2017, with so many riders swapping teams and new bikes being debuted, made it all much more interesting. But we are still all glad it’s over.

First, there was the last day of testing to get out of the way. The last day of the test is perhaps the most dangerous. A mixture of tiredness and competitiveness means riders are pushing hard in sometimes tricky conditions.

2016 MotoGP Mid-Season Review: Marc Marquez

08/04/2016 @ 1:20 pm, by David Emmett2 COMMENTS

MotoGP-2016-Assen-Rnd-08-Tony-Goldsmith-4820

2016 is the year of the impostor. Everything we thought we knew about the current riders in MotoGP has been turned on its head. Marc Márquez is a shining example of this.

He has gone from a rider who wants to win every race, even if he risks crashing out, to one who is willing to settle for less when there are no better options.

The reason for his transformation is simple: the lessons learned in the tough first half of the 2015 season.
