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: In-Depth Look at the New 2011 Suzuki GSX-R750

01/18/2011 @ 2:52 pm, by Jensen Beeler9 COMMENTS

Derek Schoeberle, our favorite Suzuki media personality, is back with a feature walk-through on the 2011 Suzuki GSX-R750 (catch his video on the 2011 Suzuki GSX-R600 as well). Like the GSX-R600, Suzuki continues to make improvements to its 750cc track weapon, namely in the form of weight reduction and mild aesthetic overhauling.

Rotating the 750cc motor backwards by 3°, Suzuki was able to shorten the wheelbase on the GSX-R750 by 15mm, and bring the front axle closer to the swingarm pivot point. With a bevy of small weight savings throughout the bike (including Brembo monobloc brakes), the new Suzuki GSX-R750 shaved 21 lbs in component weight from its bulk (a weight loss breakdown is after the jump), and tips the scales 17 lbs less than its 2010 counterpart.

Brembo to Supply Suzuki Brakes for Three Years

10/11/2010 @ 10:03 am, by Jensen Beeler4 COMMENTS

When we caught our first glimpse of the 2011 Suzuki GSX-R600 & 2011 Suzuki GSX-R 750 motorcycles, one of the things that struck us about the new bikes, besides the redesigned front fairing and 20lbs of missing mass, was the use of Brembo calipers as an OEM part. A premium part that’s usually reserved for premium brand motorcycles, Brembo and Suzuki have signed at three-year agreement that sees the Italian company supplying the Japanese manufacturer with braking bits for its GSX-R line.

2011 Suzuki GSX-R600 & 2011 Suzuki GSX-R750 Get Face Lifts and 20lbs of Liposuction for 2011

10/05/2010 @ 2:57 pm, by Jensen Beeler1 COMMENT

Suzuki made a design departure in 2009 when it revamped its GSX-R1000, while leaving the GSX-R600 & GSX-R750 unchanged aesthetically. Finally bringing the two smaller middleweight gixxers in-line with the larger superbike, the 2011 Suzuki GSX-R600 & 2011 Suzuki GSX-R750 get not only a face lift for the new model year, but also a revised engine package that has ample weight trimmings. While the new Suzuki GSX-R600 & GSX-R750’s won’t make more power than the 2010 models, the revised motor and other components shed roughly 20lbs off both the 2011 Suzuki GSX-R600 (413lbs wet) & 2011 Suzuki GSX-R750 (416lbs wet).

Making the weight-loss program possible, Suzuki went in with its surgical knife and dropped weight in a variety of places, primarily focusing on the bikes’ four-cylinder motor. Losing 4lbs in the motor alone, Suzuki lightened the pistons by 14% and the connecting rods by 12%, while increasing the ventilation holes between the cylinders, helping reduce pumping losses and improve combustion efficiency. Relocating the ECU has saved .6lbs in weight from wiring, which is sort of crazy and impressive at the same time. The new exhaust system sheds 3lbs from the prior models’, while revised injectors increase fuel efficiency by 10% and meet the strict Euro III emission standards. More info and photos after the jump.
