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.

Motus MST Drops GDI in Favor of Port Fuel Injection

03/13/2012 @ 2:49 pm, by Jensen Beeler26 COMMENTS

It is a rarity that an A&R reader is better informed than us on a topic, but one of the great things about online media is that there is an instantaneous two-way dialogue on every subject we publish. As such, a special hat-tip goes out to commenter “Bob” who spilled the beans that Motus had dropped gasoline direct injection (GDI) for the Motus MST sport-tourer that the company is soon to unveil at the Daytona Bike Week. We followed up the comment with Lee Conn, President and Co-Founder of Motus, about the comment, where he confirmed that Motus would adopt a port fuel injection & ride-by-wire scheme instead of the heavily touted GDI setup.

“Having ridden the MST’s with GDI all over America, I can report that we pioneered a really cool GDI system and it works great,” said Lee Conn. “GDI is a modern, smart and efficient way to fuel an engine, but after a lot of discussions with dealers, customers, technicians, and tuners, we concluded that there is not enough support in the current industry to roll out this technology yet.” After seeing what bikes A&R commenters were using in comparison to the Motus MST, Lee made a joke about how the Motus team would have to rethink its product messaging, and then said something that is very central to the Motus MST ethos.

Motus to Reveal Production Plans at Daytona Bike Week

03/09/2012 @ 1:37 pm, by Jensen Beeler34 COMMENTS

The last time Motus Motorcycles graced the pages of A&R it was August 10th of last year — yes, I actually went back thru the pages to check that date. Since that time, the American motorcycle startup has been busy getting its sport-tourer finalized and ready for production. Launching the Motus MST prototype at the 2011 Daytona Bike Week, Motus Motorcycles will be returning to the Floridian biking event this year to announce its production plans, pricing, and availability of its American made motorcycle.

While we’ll have to wait to hear from Motus for its official plans, we expect to hear something along the line of a production run of under 300 units, with pricing in the $30,000+ range. Certainly exclusive, it remains to be seen if Motus can sell such an expensive sport-tourer without the gadgets and gizmos that normally accompany that market segment. Featuring the gasoline direct injection (GDI) 1,645cc KMV4 engine, the Motus MST will make over 160 hp from the power plant, which is also being sold as a crate motor.

Motus KMV4 Motor Will Be Available as a Crate Motor

08/10/2011 @ 12:02 pm, by Jensen Beeler13 COMMENTS

Talking to Lee Conn when Motus was on its US tour here in California, the Motus founder revealed that part of Motus’s business plan incorporates selling the Katech-designed KMV4 motor as a crate motor for enthusiasts and tuners. Though the Motus MST motorcycles will be using a 1,645cc 160+ hp version of the gasoline direct injection (GDI) motor, Katech and Motus have left plenty of beef to the KMV4’s cyclinder housings, allowing the V4 lump to be bored out to a 2L displacement.

Motorcycle upstart Motus Motorcycles continues to press forward with its MST-01 sport-tourer, and has released a video that talks more about the development of their 1645cc gasoline direct-injection V4 motor: the KVM4. Balking at the advice of others not to build their own powerplant, Motus has teamed up with Katech to design an in-house motor for the Motus MST-01.

Motus MST-01: Direct Injection, 2 Valves per Cylinder, 1650cc, 140hp, Made in America

01/16/2010 @ 6:52 pm, by Jensen Beeler13 COMMENTS

Motus Motorcycles has trickled out a bit more information about its Made in America MST-01 sport-tourer, giving CycleWorld their obligatory first look. What do they have to report? A 1650cc V4 motor with two valves per cylinder that features direct injection, which sums up to equal 140hp. More on that and photos after the jump.
