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 Assen: Weather Again, Hard Wets, & Why Timing Matters

06/25/2016 @ 6:16 pm, by David EmmettComments Off on Saturday MotoGP Summary at Assen: Weather Again, Hard Wets, & Why Timing Matters

MotoGP-2016-Assen-Rnd-08-Tony-Goldsmith-3048

In the previous 85 editions of the Dutch TT at Assen, we have seen some pretty spectacular Saturdays. In the 86th edition, with the race moved to Sunday, Saturday lived up to the expectations raised by the previous 85.

It was a wild and weird day, both morning and afternoon, with the weather being the main protagonist once again. There were crashes, fast dry laps, fast wet laps, and some smart strategy in the chase for pole. It was a good day indeed.

With Friday’s heat having dissipated, the MotoGP riders faced a fresh set of challenges. Overnight rain and light clouds meant track temperatures were much cooler. That meant that the medium front tire was suddenly a much more tricky proposition, catching a number of riders out.

Jorge Lorenzo fell at the Ruskenhoek after the front tire let go, while Marc Márquez made one of the most remarkable saves of recent years, after locking the front completely braking for Turn 1.

What happened? It’s hard to tell from the video online at the MotoGP.com website, or via the MotoGP Twitter feed, but afterwards, Márquez explained that the front locked without warning.

“From the first point of the brake, the front wheel locked, and then I released the brakes and it was a big moment,” the Repsol Honda rider said.

Tuesday Summary from Valencia: Learning To Use Bridgestone’s Wet Tires

11/12/2014 @ 9:13 pm, by David Emmett2 COMMENTS

scott-redding-valencia-test-honda-motogp

It is a good job the post-race test at Valencia is three days long. The weather in Valencia in November is usually very good, but it can turn, and you can lose track time to rain. That was certainly the case on Tuesday, rain starting early in the morning, and coming in waves all day.

It meant the track was wet throughout Tuesday, only the depth of water on the track varying. The heavy rain meant that most riders decided to sit out the day, only ten riders putting in any laps.

With the track the way it was, the finishing order was not really relevant. What was more important was gaining time on the track, and for several riders, getting to grips with Bridgestone’s wet tires. Eugene Laverty, Loris Baz, and Marco Melandri, all of whom have moved over from World Superbikes, needed to adjust their minds to the Bridgestones.

Friday Summary at Misano: Wet Weather, A Terrible Surface, & A Raft of Rider Announcements

09/13/2014 @ 12:06 am, by David Emmett7 COMMENTS

For anyone on a budget, Misano is one of the cheaper MotoGP rounds to attend. Ticket prices aside, the area has a large amount of tourist accommodations, and the race takes place right at the tail end of the tourist season, when hotel prices are starting to drop.

Buses run to and from the circuit from Riccione, making transport to and the track affordable. Misano is a great circuit to go to if you are trying to keep costs to a minimum.

Misano may be a cheap weekend for fans, but it certainly wasn’t cheap for the teams in all three classes in MotoGP. The rain-drenched conditions on Friday saw riders crashing left, right, and center, in Moto3, Moto2 and MotoGP. They racked up a grand total of 62 crashes in all three classes, in just a single day.

Given that crash damage on Grand Prix machinery tends to start at a minimum of around a thousand euros, going up arithmetically with the severity of the crash and the class the bike is racing in, a conservative estimate of the grand total for repairs on the first day of practice would be enough to pay for a ride in Moto3. Or possibly even on a MotoGP Open class bike.

The cause of those 62 crashes? The water certainly didn’t help. Rain fell through the night and all day, leaving the track soaked and standing water on some part of the track. But it wasn’t just the water, the surface of the track itself was very poor, and rubber left on the track made braking on the racing line a treacherous affair, riders in all three classes going down as the front locked up.

The fact that Bridgestone had started the MotoGP riders off on the harder of the two wet tire options didn’t help either. It was an understandable choice: in previous years, when riders have used the softer wet tire, they have ended up being destroyed at Misano.

Friday Summary at Brno: Yamaha’s Big Improvement, Elbow Down in the Wet, & The Factory Bosses Speak

08/15/2014 @ 1:35 pm, by David Emmett5 COMMENTS

marc-marquez-repsol-honda-brno-motog-hrc

The first day of practice at Brno turned out to be a day of two halves. The morning was glorious, sunny and relatively warm. Clouds began gathering shortly after lunch, and the first spots of rain started to fall just as FP2 for the Moto3 class came to a close.

The rain grew steadily heavier for the first half of the MotoGP afternoon practice session, easing up and stopping with some ten minutes to go. By the time the Moto2 bikes took to the track, the circuit was already drying, though it only really dried out completely towards the end of Moto2.

The two halves of MotoGP practice showed the same picture, however. Marc Marquez is fast in the wet and fast in the dry, and clearly looking comfortable on the Repsol Honda.

Teammate Dani Pedrosa is also quick in both conditions, though a little closer to Marquez on a wet track than on a dry track. In the dry, Jorge Lorenzo is very close to Marc Marquez, but in the wet, both he and Movistar Yamaha teammate Valentino Rossi are a second off the pace of the Repsols.

WSBK: “Wet” Superpole Qualifying at Assen

04/21/2012 @ 11:00 pm, by Jensen Beeler3 COMMENTS

With the rain playing a factor during the Qualifying Practice sessions, riders like Max Biaggi were caught out, and left high and dry during an otherwise water-filled build up to today’s Superpole qualifying. As the Roman Emperor watched from the sidelines, World Superbike Race Direction deemed the Superpole a wet session, reducing the qualifying event to two twenty-minute sessions, with only the top eight riders going onto the second round. With the track actually dry for Superpole 2, all eyes were on Tom Sykes, to see if the Kawasaki rider could make a hat trick out of his qualifying streak.

MotoGP: Rain Threatens Racing at the Catalan GP

06/05/2011 @ 12:20 pm, by Jensen Beeler1 COMMENT

When the Catalan fans’ eyes weren’t on polesitter Marco Simoncelli, they were looking up at the clouds in Barcelona, to see if they would rain on the Spanish track during today’s MotoGP racing action. With the Catalan track damp in some sections, riders started out on slick Bridgestone tires, hoping for the best in what would fall from the heavens in the coming laps.

Disappointing for American fans, was the news that Colin Edwards had broken his collarbone on Friday, and unfortunately MotoGP medical would not let the Texan start today’s race, thus making the 2011 Catalan GP the first time the Texan Tornado has missed a race since 2003. Edwards seemed confident he’d be back for Silverstone though.

Also absent from the grid was the injured Dani Pedrosa, who broke his shoulder in an incident at the French GP with Simoncelli, making the Italian persona non grata in Spain this weekend. Luckily for Spanish fans, Jorge Lorenzo was on the front row for the start and appeased the masses, but he was behind Casey Stoner who had been consistently quick all week long.

MotoGP: Who Didn’t Crash in the Spanish GP?

04/04/2011 @ 1:44 am, by Jensen Beeler1 COMMENT

The sunny Spanish weather gave way to rain this Sunday, as the Spanish GP got underway with 123,750 rain soaked MotoGP fans in attendance. While the practice sessions and qualifying showed the usual suspects at the top of the time sheets, the slippery conditions in the rain saw some new faces posting up strong times in the Sunday morning warm-up session.

Clearly the change in weather meant all bets were off for the MotoGP racing at Jerez, but the racing that took place certainly wasn’t what fans were expecting — as the rain relented, so did the tires. Add into the mix that this was the 2011 MotoGP Championship’s first wet race, and you’ve got a recipe that means more than just a few riders (nine total) ended up in Jerez’s gravel traps by the day’s conclusion. Find out all about it after the jump.

MotoGP: The Spanish GP Could Get Interesting – Valentino Rossi Second Fastest in Warm Up as Rain Hits Jerez

04/03/2011 @ 2:35 am, by Jensen Beeler4 COMMENTS

We knew as the rain hit Jerez this weeks that the weather would be a significant factor at the Spanish GP, and the added moisture on the track has already affted the MotoGP riders as they took to the track for their warm-up session this morning. If you placed your money on Casey Stoner to win the Spanish GP, your money might be safe, as the Australian is still eclipsing the field with his lap times.

However with Valentino Rossi slotting in as second quickest this morning, and Nicky Hayden a not-so-distant fourth, it would appear that the Ducati Desmosedici GP11 favors the wet weather a bit more than their counterparts (check out Ben Spies down in the fourteenth position).

As for the other Repsol Honda front-man Dani Pedrosa, you’ll find him down in the timesheets somewhere around the seventh position. There’s of course a whole race still to be run before we’ll see the results of the Spanish GP, but Rossi/Ducati fans have at least some glimmer of sunshine in an otherwise rainy day at Jerez.
