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.

Video: Bostrom vs. Hayden – The Duel Continues at NJMP

12/13/2012 @ 6:06 am, by Jensen Beeler4 COMMENTS

Another side-by-side comparison video from our friends at the Michael Jordan Motorsports (click here for their video from Homestead-Miami Speedway), we take a lap with Ben Bostrom and Roger Lee Hayden around New Jersey Motorsports Park’s Thunderbolt course (home of the world’s longest decreasing radius turn).

Riding his Jordan Suzuki GSX-R1000 in the first qualifying session, Bostrom sets an impressive 1’22.803 lap time (the third fastest of the session), while Hayden on the National Guard Jordan Suzuki GSX-R1000 does a 1’22.812 here in the second qualifying session.

Impressively enough, both MJM riders were within a tenth of a second of each other at the end of both qualifying sessions. Enjoy some synchronized apexing after the jump.

Video: Ben Bostrom vs. Roger Lee Hayden at Homestead

11/15/2012 @ 4:04 pm, by Jensen Beeler11 COMMENTS

One of our favorite parts about MotoGP’s recent coverage are the slow-motion shots of riders going through corners, especially when the Dorna folk in the switchroom line-up a few riders through the same turn, giving us a sampling of the different riding styles that exist in the premier class. It is through this sort of coverage that you begin to see the real art behind riding a motorcycle at speed, not the brute force brawl that it looks like in real-time.

Here we have another side-by-side comparison, quite literally actually. Dropping a 1-2 qualifying session at Homestead this year, Roger Lee Hayden was fastest on his National Guard Jordan Suzuki GSX-R1000 (1’22.746), while Ben Bostrom qualified 2nd on his Jordan Suzuki GSX-R1000 (1’22.857). What is interesting in this video is the subtle differences between the two riders, which results in over a one-tenth of a second difference at the finish line.

Hayden & Bostrom Test at Homestead-Miami Speedway

01/03/2012 @ 3:11 pm, by Jensen Beeler6 COMMENTS

The start 2012 AMA Pro Road Racing series is almost upon us, and the folks at Michael Jordan Motorsports are rapidly gearing up for the new season. Traveling down to the Homestead-Miami Speedway in Florida, MJM riders Ben Bostrom and Roger Lee Hayden took their Suzuki GSX-R1000 race bikes around newly added track for the first time. While Bostrom and Hayden won’t have to race at Homestead-Miami until September 23rd, the season-opener at Daytona, Florida is rapidly approaching and only two and half months away.

Shooting the Homestead-Miami Speedway test with some on-board cameras, the Michael Jordan Motorsports team has put together a great three minute clip that stars Bostrom’s boot, among other things. Joking aside, the video is well-put together (a rarity in the AMA paddock), and has some great shots of Bostrom’s shifting and knee-slidding around the Floridian track. Look for #23 on the Jordan Suzuki, while Roger Lee will again represent the men and women of the Army National Guard on the #54 bike.

How Jason Pridmore Scared the Crap Out of Me…Twice

05/29/2011 @ 7:09 pm, by Jensen Beeler10 COMMENTS

It all started innocently enough, as I was having dinner with some friends from Dainese before the West Coast Moto Jam, they suggested that I do a two-up ride with Jason Pridmore on the National Guard Suzuki Superbike. “Yeah, that’d be really cool,” I said in response, trying not to burst with excitement as to how awesome and unique I thought the experience would be. Barely sleeping the night before, I arrived Saturday morning at Infineon Raceway, and got decked out in the Dainese/AGV gear that was provided, and headed over to the National Guard Jordan Superbike team pits where we met up with Jason Pridmore.

I was accompanied by several National Guardsmen and some fans (you can win a two-up ride by following Jason on Twitter), and before we got started the AMA & FIM World Endurance veteran introduced the program to us. “Before we start has anyone here been drinking?” asked Pridmore – the day had been hot, and this was a NASCAR venue after all. Raising his hand and looking at the ten of us, “Oh, so just me?..let’s get started” continued Pridmore. Yeah…it was going to be like that.

Swinging my leg over the pillion seat on the Suzuki GSX-R1000, Jason gave me a run-down again on the instructions, and asked me how I was feeling. “I’m pumped,” I replied. “Go as fast as you can.” Now let us take a moment to evaluate who this is the point where I made my critical error in the day, as I suspect Pridmore takes a special joy in scaring the life out of hapless moto-journalists who find themselves on the back of his motorcycle.

Actually, Jason makes it a point to say in his briefing that the goal is to make the ride fun for every passenger, and consider that a goal achieved, as you’d be hard pressed to find someone getting off the back of Jordan Suzuki without a grin that stretches ear-to-ear. However, I suspect that if you’re a motorcycle blogger with more ego than commonsense, this whole concept is forfeit, and it’s at this point in time that I would like to apologize to every pillion I’ve ever had on the back of my street bikes (you know who you are).
