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: Weird Grids, Hot Tires, And Team Troubles

06/24/2017 @ 5:38 pm, by David EmmettADD COMMENTS

Motorcycle racing is an outdoor sport. The riders are at the mercy of the elements. Not just the riders, but the teams and factories too. A bike that works well in the dry may be terrible in the wet.

A bike that is strong in the wet may struggle when conditions were mixed. Finding the right balance when conditions change can throw the best laid plans into disarray.

All of these questions were multiplied by the weather at Assen. With nothing between the circuit and the North Sea but a row of sand dunes, the odd high rise office block, and a hundred kilometers of pancake-flat farmland punctuated by the occasional tree, the wind, sun, and rain blow out just as quickly as they blow in. The weather at Assen is as fickle as a pretty teenager in a crowded disco.

That made it tough for MotoGP at the Dutch circuit. Searching for the right setup was both perilously difficult and ultimately futile, for as soon as you found something in the right ballpark for the conditions, the rain would come or the track would dry out, and you would have to start all over again.

Add in tarmac which has fantastic grip in the dry but diminishing grip in the wet, and you had a recipe for, if not chaos, then at least a fairly random mix of riders topping qualifying.

Saturday MotoGP Summary at Catalunya: A Primer on Asphalt, And A War of Attrition

06/11/2017 @ 2:01 am, by David EmmettADD COMMENTS

Sunday at Barcelona is going to be a war of attrition. Everything is conspiring against the riders, and most especially the tires.

Temperatures are expected to rise even higher than they were on Saturday, when air temperatures hit over 32°C, and track temperatures climbed to 55°C and above.

Those are punishing temperatures in which to race a MotoGP bike, especially at Montmelo, where the heat gets trapped in the bowl of hills which holds the circuit.

Then there’s the tires. There is much complaining about the lack of grip and the fact that grip drops off a cliff after seven or eight laps.

It would be more accurate to blame that on the track, though: the Circuit de Barcelona-Catalunya has not been resurfaced in twelve or thirteen years, and is very heavily used, both by bikes and by cars.

That has created a surface which is both too smooth to provide grip, while simultaneously being incredibly abrasive.

That sounds contradictory, so when Michelin boss Nicolas Goubert spoke to a group of journalists on Friday night, I asked him to explain. The Frenchman explained that grip and abrasiveness came from two different parts of the surface.

Asphalt (or rather, a road or racing surface) consists two parts: binder and aggregate. Aggregate is basically small stones, specially selected for size and shape. Binder is usually a special formulation of bitumen, often containing other ingredients.

Saturday MotoGP Summary at Mugello: Rossi’s Recovery

06/03/2017 @ 11:12 pm, by David EmmettADD COMMENTS

Imagine you find yourself at the start of a 40-minute session of track time, at one of the greatest racing circuits in the world, sat astride one of the most sophisticated racing motorcycles in the world, with the Tuscan sun beating down from clear skies, and the hillsides echoing to the roar of tens of thousands of delirious fans. What would you do?

If you’re a Moto3 rider competing at the Italian Grand Prix, then the answer is simple: you sit in your pit box for five minutes, then pootle out into pit lane, spending all your time looking backwards.

You are finally persuaded to head out of pit lane over the crest and down towards one of the most challenging corners of the season, so you potter around at a miserable 30 km/h, constantly looking behind you in the hope of finding a faster rider coming up behind you at speed. You repeat this for the full session, interspersed with the odd hot lap.

The situation got so bad that in one of the hospitality units after the day was over, one person came over to us and asked if the Moto3 qualifying session had been red-flagged. They had been working through the session, and had noticed that the track had gone completely quiet.

But it was not red flags that stopped the action, it was the desperate search for exactly the right tow. The trouble is, when all 31 Moto3 riders are waiting for a tow, there is no one left to be giving them.

Saturday MotoGP Summary at Le Mans: Zarco’s Brilliance, Rossi’s Non-Retirement, And Miller’s Mental Fortitude

05/21/2017 @ 1:40 am, by David EmmettComments Off on Saturday MotoGP Summary at Le Mans: Zarco’s Brilliance, Rossi’s Non-Retirement, And Miller’s Mental Fortitude

It has been a tough weekend for a lot of people at Le Mans. The weather has done just about everything to confound and perplex the riders, conditions changing every session.

Friday went from wettish to very wet, Saturday went from drying to almost completely dry. There hasn’t been a single session of stable weather with a consistent and unchanging track.

That has caused a lot of problems, especially in MotoGP, shaking up the qualifying system based around the combined times through all three free practice sessions. For the fans, though, it’s been fantastic, producing two of the most exciting qualifying sessions we have seen for a while.

Tricky conditions in free practice put Dani Pedrosa, Andrea Dovizioso, Jorge Lorenzo, and local hero Johann Zarco into Q1, producing fireworks in the battle for who gets through to Q2.

Then, in Q2, the battle happened all over again, this time in a straight up slugfest for the front row. That went right down to the wire, the first three safe only once the dust had settled.

The weather reignited the debate over MotoGP’s qualifying system, a common complaint among several riders, and also a regular topic at the Safety Commission, the meeting where riders and organizers gather to discuss how to make racing safer.

Andrea Dovizioso voiced the concern on Saturday, despite having made it through Q1 and into Q2. “It’s really stressful, these rules for everybody because every practice has to be a qualifying,” the Ducati rider said. “You have to be in the top 10 because the weather can change.”

Sunday MotoGP Summary at Jerez: An Imperious Pedrosa

05/07/2017 @ 11:59 pm, by David EmmettComments Off on Sunday MotoGP Summary at Jerez: An Imperious Pedrosa

Jerez, the Spanish round of MotoGP, and the first event back on European soil, would in the end come down to a trial of grip. The riders and teams who understood the circumstances best, exploited their strengths, and disguised their weaknesses would come out on top.

In all three races on Sunday, the cream rose to the top. Despite rising temperatures and falling grip levels, the smart riders and teams triumphed in all three classes.

Grip was already poor for Moto3, but the lighter bikes and their smaller tires are the least affected of the three classes. Things got a lot worse for Moto2, riders struggling for grip, and the race decided by one of the two men battling for victory crashed out a third of the way into the race.

The burning Andalusian sun raised track temperatures even higher for MotoGP, and that would prove decisive in the race. Those capable of handling the poor grip triumphed, those who had counted on their good form from the morning warm up transferring to the race came away bitterly disappointed.

In Moto3, KTM made a welcome return to the front, with the Austrian bikes back to challenge the hegemony of Honda in the smallest of the three classes. That race would be won in a brilliant last-corner move when the two riders battling for the lead opened the door for the bike in third.

In Moto2, a tense duel would be settled by a mistake, leaving the last man standing to deal with staying concentrated for the second half of the race. And in MotoGP, a thoroughly imperious display saw one rider conquer Jerez, leaving a bloodbath in his wake. Jerez saw three deserving winners emerge.

Saturday MotoGP Summary at Jerez: Fast Hondas, Deceptive Yamahas, Losing Winglets, & Orange Elation

05/07/2017 @ 11:09 pm, by David EmmettComments Off on Saturday MotoGP Summary at Jerez: Fast Hondas, Deceptive Yamahas, Losing Winglets, & Orange Elation

Coming into the weekend of Jerez, we knew several things to be absolute certainties. 1. Jerez is a Yamaha track. 2. Ducati always does terribly at Jerez. And 3.

The Hondas will struggle against the might of the Yamaha. After qualifying, a swift dose of reality has flushed those preconceptions out of our systems, showing them up for the fallacies that they are.

After qualifying at Jerez, we have an all Honda front row. Two Yamahas start from the second row, but their performance during both qualifying and free practice was far from convincing.

The first Ducati sits on the third row, but during practice, Jorge Lorenzo made the Desmosedici GP17 fly, finishing second in FP3 and fourth in FP4.

Where did this shake up come from? The issue is mainly one of grip. After the rain on Friday, there is very little rubber on the track, and the warmer track temperatures have made Jerez its normal, greasy self.

The Yamahas perform well when grip is high, whether that be in warmer or cooler temperatures. Extra grip merely helps the RC213V want to wheelie, something for which it needs little encouragement anyway.

Robbed of its winglets, the Ducati needs extra rear grip to get good drive out of corners, and exploit its strongest point.

Assen WorldSBK Debrief – Saturday

04/30/2017 @ 12:09 am, by Kent Brockman3 COMMENTS

The tension that has been building between Jonathan Rea and Chaz Davies finally spilled over at Assen. Three years of competing with one another for race wins and championships has strained their relationship, and on Saturday at Assen it reached its breaking point.

On the final laps of Superpole, Davies was on a flying lap and came across Rea through Turn 7. Being forced to sit up and avoid the touring Kawasaki, emotions got the better of Davies, and at the end of the session he hit out at Rea in parc ferme.

“You stayed on three quarters of the track,” stated Davies after qualifying third. “I don’t know how tight a line you can pull out of that left, but I’m three-quarters of the track out there.”

“You were in the way mid-way through the corner, and then on the exit I had to pick it up because you were three-quarters across the track, if I didn’t I’d have cleaned you out! Next time I’ll smash you from the inside and we’ll see what happens.”

Saturday MotoGP Summary at Qatar: The Blame Game

03/26/2017 @ 4:15 am, by David Emmett8 COMMENTS

Saturday was the kind of day that makes you question the wisdom of allowing Qatar to be the first race of the MotoGP season, and to hold the race at night.

Doing one or the other – either being the first race of the season but holding it during the day, or taking place later in the year and racing at night – is feasible, but doing both is a risk.

If it wasn’t for the fact that the sanctioning fee the Losail International Circuit at Qatar pays to Dorna for the privilege basically covering the overseas travel budget for the teams for the entire season, the MotoGP season opener would be very different.

It was an entirely wasted day. Or perhaps not entirely wasted: we learned that the Qatar circuit badly needs the drainage fixed. Whatever the decision on racing in the rain, when it does rain, the track and the run off areas just don’t drain fast enough.

That led to Loris Capirossi, Dorna’s representative in Race Direction, trying to explain in increasingly exasperated tones that there was no point trying to test during the day or at night, because there was simply too much standing water in the gravel traps and in certain sections of the track to allow it to be used safely.

Capirossi was speaking at an impromptu press conference organized directly after the qualifying press conference, to explain why all on-track action had been cancelled on Saturday.

It had started with the cancellation of the Asia Talent Cup, and a revised schedule was issued containing a track inspection, then a twenty-minute session for the riders to go out and see whether it would be possible to ridein the wet under the floodlights.

But as each schedule approached, events were delayed. In the end, the entire day was cancelled. The track was unusable after such intense rainfall.
