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.

India’s Royal Enfield Acquires the UK’s Harris Performance

Indian motorcycle brands getting involved with Western companies for R&D isn’t anything new, in fact the entire Erik Buell Racing story seems to center around that very issue.

So, it shouldn’t shock anyone to hear that the iconic Royal Enfield motorcycle brand has acquired famed British performance house Harris Performance.

“Royal Enfield is working on its new generation of products and platforms; to have the Harris Performance team dedicatedly working with us will clearly enhance our engineering and product design capabilities,” said Siddhartha Lal, CEO Royal Enfield.

Trackside Tuesday: Do Motorcycles Dream of Electric Sheep?

OSU-Rob-Barber-TT-Zero-Isle-of-Man-TT-Richard-Mushet

Now the dust has settled on another TT, a look back over the numerous pages of lap times and race results can only tell us so much. With so many incredible stories to be told it is difficult to choose one for this article.

From the blatantly obvious, such as; Dunlop’s incredible four wins, McGuinness’ new outright lap record or Ian Lougher rounding out his career on the Mountain course, which spanned four decades, tallying nine wins plus an additional nineteen podiums.

To the equally awe-inspiring, like; David Johnson’s impressive return to the island on privateer machinery, Dave Madsen-Mygdal completing his 100th TT race, and the first ever Chinese competitor at the TT, the likeable Cheung Wai-On.

Above all these, one team’s story caught my eye – the Buckeye Current team from the Ohio State University’s College of Engineering, whose Honda CBR1000RR-based electric motorcycle was tackling the Mountain course.

Consisting of a number of students from various science and engineering programs, the team’s RW-2 bike was the sole American entry from an educational institute and was pitting itself against three other teams from similar institutes and six non-collegiate teams from across the globe.

CAD Drawings of the Ducati Streetfighter 848

04/11/2012 @ 5:42 pm, by Jensen Beeler9 COMMENTS

Overall, our impressions of the 2012 Ducati Streetfighter 848 was that the new baby Fighter from Ducati, is a well-improved upon successor to the original Ducati Streetfighter 1098. Helping differentiate the SF848 from the higher-spec, though otherwise identical, Streetfighter 1098 S, the Streetfighter 848 takes the geometry from the Ducati Superbike 848, which means it gets a much-better handling 24.5° rakes. Ducati has also brought over the Testastretta 11° engine, which made its first debut on the Ducati Multistrada 1200, and then found its way onto the Ducati Diavel.

Smoother and easier to operate, the new Streetfighter’s 849cc motor may be down on power compared to its Superbike counterpart (132 hp at its peak, compared to the Superbike 848 EVO’s 140hp), but the SF848 has a much flatter torque curve and a power band that extends into a more useable range for urban and aggressive street riding. When compared to its predecessor, just about the only thing we don’t like about the Ducati Streetfighter 848 is the foot clearance issue with the shotgun exhaust, which limits the movement of a rider’s right foot on the Streetfighter’s peg.

Releasing these CAD drawings at the 2012 Ducati Streetfighter 848 US press launch, maybe some eagle-eyed industrial designers can come up with a solution for this reporter’s kneecap. CAD renders after the jump.

The Mission R with Its Clothes Off

01/18/2011 @ 12:37 pm, by Jensen Beeler10 COMMENTS

The Mission R, the latest creation to come from San Francisco-based Mission Motors, looks like any typical gasoline-powered sportbike (well, any really good looking gasoline-powered sportbike), and that’s sort of the point behind the machine: an electric motorcycle that can excite petrol-heads and electron nerds alike. Although the Mission R was made to draw mainstream appeal, today we see further proof that any resemblance to modern ICE motorcycles was made to be only skin deep.

Beneath the carbon-laid fairings of the Mission R, we see a hint of the bike’s unique chrome-moly trellis frame that mates to a previously hidden headstock/front sub-frame unit that was made by Speedymoto and designed by James Parker (of GSX-RADD fame). With the Mission R’s mass centralized around the 141hp 3-phace AC induction motor, Parker also had to contend with Mission’s carbon enclosed two-tiered battery pack that comprises the bulk of the race bike’s weight.

Read after the jump as Parker walks us through his process and thoughts on designing the Mission R, and be sure to check out the photo galleries for an up-close look.

Hands on with the MotoCzysz Frame

03/18/2010 @ 3:31 pm, by Jensen Beeler2 COMMENTS

Ending our two-part series that looked at the the MotoCzysz E1pc, we ask ourselves: why do motorcycles look the way they do? Probably the best answer to this question is that motorcycles today represent an amalgamation of 100 years of design evolution centered around the internal combustion engine. When we look at motorcycle racing, we see the design in its purest embodiment of function over form. While surely some semblance of aesthetics remains, the ultimate goal is to shave the next tenth of a second off a lap time. Each minor improvement adds up, and these aggregated can translate into substantial improvements when racing the clock and the competition.

So it surprises us when we look at electric motorcycle racing and see so many teams approaching their designs with the same ideas and concepts that were born out of this century of internal combustion engine (ICE) racing. While the two offshoots of the same branch carry over with them many similarities, the fundamentals of attaching wheels, suspension, and seat to a running motor has changed, and with that change surely there would be a large movement to rethink the way we build motorcycle frames. The fact of the matter however is that many electric motorcycle designers choose to pursue cramming an electric motor and batteries into a frame, and ultimately into and architecture, that was refined for a gasoline pumping motor and doesn’t fully integrate the chassis’s from with its function.

In an industry that rethinks motorcycles from the ground up, the biggest paradigm shift has been left out by all but a few teams and manufacturers. Looking for the next generation in motorcycle chassis design, Asphalt & Rubber recently got to sit down with Michael Czysz to get an up-close look at the 2009 MotoCzysz E1pc electric motorcycle, and also got a sneak peak at the 2010 frame and chassis. As one of the few entities to rethink how a motorcycle should be design and produced, Czysz’s insights into his design give a glimpse as to what the next 100 years of motorcycle evolution will look like.

Kinekt Design Gear Ring – Bling for Motorcyclists

03/06/2010 @ 9:37 pm, by Jensen Beeler1 COMMENT

When it comes to rings, women get all the bling, leaving men to choose bands that have a de minimus amount of creativity to them. Well that’s all about to change as Kinekt has come up with a ring that should warm the hearts of engineers and gear-heads alike. The Kinekt Design Gear Ring is both functional, in that it turns on itself…not that it actually serves any purpose other than as a constant reminder of your love and devotion. Check the video of it in action after the jump.
