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 Summary at Silverstone: Of Used Tires, Tough Love, & The Chance of Rain

08/29/2015 @ 10:59 pm, by David EmmettComments Off on Saturday Summary at Silverstone: Of Used Tires, Tough Love, & The Chance of Rain

Saturday-Silverstone-British-Grand-Prix-MotoGP-2015-Tony-Goldsmith-1581

Predicting how a MotoGP race will play out is hard. Scratch that, predicting how a MotoGP race will play out is downright impossible. We scour the sector and lap times, talk to as many riders as possible, try to make sense of what they tell us, and take our best guess based on all we have learned.

And inevitably, we get it wrong. Because there was something we missed, or because some random factor intervened, or because we didn’t pay enough attention to what the riders were telling us, or perhaps paid too much attention to it. Which is why you should probably take the following with a pinch of salt.

After qualifying and practice at Brno, we confidently predicted one of the best races of the year, with Jorge Lorenzo and Marc Márquez setting almost identical pace during free practice.

The chase lasted for five laps, before Lorenzo picked up his heels and disappeared, riding a perfect race to an unstoppable win, and killing any burgeoning excitement stone dead.

Silverstone looks like being very similar. There are two riders who are clearly a step ahead of the rest, and on the basis of practice times on Saturday, their pace is very similar indeed.

Though you wouldn’t say that just based on the headline numbers: in FP3, Jorge Lorenzo destroyed the rest of the field, beating Márquez by nearly half a second.

In the afternoon, during FP4, Márquez returned the favor, laying down a withering pace to put over eight tenths on everyone else, and posting a string of ten laps, the slowest of which was faster than fastest lap set by any other rider on the field.

The difference between Lorenzo’s FP3 lap and Márquez’ FP4 lap? Just 0.062 seconds, in Lorenzo’s favor.

Tires are what made the difference. Lorenzo put a brand new tire on for the last two laps of FP3, and obliterated the rest of the field. Márquez put a brand new medium tire in FP4, and blew the field away, then slapped in a new hard tire, and was fast with that too.

In FP3, Márquez was working on getting the best out of old tires, in FP4, Lorenzo was doing the same, as well as trying out a setup change that simply did not work.

Two riders, similar pace on new tires, both much faster than the rest. Who will come out on top? At this point in time, it is impossible to say. What it will come down to is who manages tires the best.

Preview of the British GP: The Ryanair Round, Silverstone’s Peculiar Challenges, & The Silly Season Latest

08/28/2015 @ 7:34 am, by David Emmett3 COMMENTS

silverstone-circuit-track-map

The Irish budget airline Ryanair gained something of a reputation for being, shall we say, creative with the names of the airports it flies to.

Fancy a trip to Sweden? They will fly you to Stockholm Skavsta, a mere 100 km from the city of Stockholm. The same trick is played out time and time again: Paris Beauvais? Beauvais is a charming French city, and well worth a visit, but it is very long way from the French capital. Munich West (Memmingen)? 112 km west of the Bavarian capital.

So perhaps we should call this British GP the Ryanair MotoGP round. Officially, it is being run by the Circuit of Wales, located in Ebbw Vale, South Wales.

Yet the race is to be run around the Silverstone circuit, nearly 200 km further East. Close, it is not. How did it end up at Silverstone? Thereby hangs a long and convoluted tail.

The Massive MotoGP Silly Season Update

Brno was a busy time for teams, managers and riders. Apart from dealing with jet lag and the sweltering heat, silly season kicked off in force at the Czech round of MotoGP.

The summer break and the chaos which ensued from the situation around the Forward Racing team put everything on hold over the summer, with tentative talks starting at Indianapolis.

Those talks, and events outside the paddock, helped clarify the situation, and at Brno talks began in earnest. The empty spaces on the MotoGP grid are starting to be filled.

Preview of the German GP: How Great Last Corners Create Epic Battles, & Silly Season Starting

07/09/2015 @ 7:01 am, by David Emmett7 COMMENTS

sachsenring-track-map

What makes for great racing? Many things, but great last corners really help. A great last corner, or sequence of corners, allows riders to attack the bike ahead of them, and take one final shot at victory.

Even better is when the option to attack offered by the final corner comes with some risk attached: getting ahead is one thing, but staying ahead to the line is quite another.

MotoGP moves from one track with a last corner which guarantees spectacle to another. The final GT chicane at Assen produced fireworks with the clash between Valentino Rossi and Marc Márquez, and the last two corners at the Sachsenring offer similar opportunities.

At Assen, the hard-braking right corner is followed by a quick flick left, giving the defending rider the chance to counterattack if he is passed.

At the Sachsenring, the long drop down the steep, steep hill provides the ideal platform to launch an attack from, diving up the inside on the brakes on the way into the penultimate left hander.

That line comes at a price, though, as it forces the attacker to run wide on the exit. That opens allowing the defending rider to strike back up the inside on the approach to the final turn, the last left uphill towards the line.

Even entering that corner ahead is no guarantee of the win: like Turn 12, Turn 13 offers two lines, inside and outside, both of which can be used to pass.

Ducati’s Qatar Podiums Means Fuel Allowance Cut

03/31/2015 @ 3:00 pm, by David Emmett4 COMMENTS

Friday-Losail-MotoGP-Grand-Prix-of-Qatar-Tony-Goldsmith-1041

Ducati is to lose the first of the special concessions granted at the start of the 2014 season.

The two podiums which Ducati scored at Qatar bring its dry podium total to three, which means that the fuel allowance for all Factory Option Ducati bikes will be cut from 24 liters to 22 liters, as we reported on Sunday night.

The allowance of 22 liters is still 2 liters more than the 20 liters used by Yamaha and Honda, who race without any concessions.

Q&A: Danilo Petrucci – “I Was Proud To Be Able To Follow Rossi For Two Laps”

02/09/2015 @ 1:08 pm, by David Emmett4 COMMENTS

Danilo-Petrucci-Sepang-test-Pramac-Ducati

Danilo Petrucci has always been one of the most underrated riders in MotoGP. The Italian came into the class from Superstock, where he finished runner up in the Superstock 1000 class.

He joined the IODA Racing team, where he started off on the team’s own Aprilia-based machine, before switching to the Suter BMW. Last year, he rode the Aprilia ART machine for the IODA, before finally getting a shot at a proper MotoGP machine this year with Pramac.

Since making the move, Petrucci has quickly got up to speed, but three years on underpowered bikes have left the Italian with a riding style problem to fix.

Like many other former Open class and CRT riders, he is used to carrying corner speed, to compensate for a lack of horsepower.

Now on a Ducati Desmosedici GP14.1, he has horsepower to spare, and needs to adapt his riding style to stand the bike up earlier and make use of the available acceleration.

I spoke to Petrucci after the last day of testing at Sepang, where he explained what he had been working on. He talked of changing his riding style, developing electronics for the factory team, and getting help from his friend Valentino Rossi.

2015 MotoGP Sepang 1 Test Preview – What Can We Expect As MotoGP Returns To Action?

02/03/2015 @ 12:11 pm, by David Emmett6 COMMENTS

Living-The-Dream-Sepang-Malaysian-Grand-Prix-Isle-of-Man-Road-Racing-Tony-Goldsmith-20

The 2015 MotoGP season kicks off tomorrow. On Wednesday, the riders take to the track once again at Sepang to continue the development on the bikes they will be racing this year, and to test out the new updates the engineers have been working on during the winter break.

And yet the two most important and interesting developments won’t even be at the first Sepang test.

Ducati’s much-anticipated Desmosedici GP15 is not quite ready for primetime, and so will not make its public debut until 19th February at the launch in Bologna, and not make its first laps in public until the second Sepang test at the end of this month.

Yamaha’s fully seamless gearbox – allowing both clutchless upshifts and downshifts – will also wait until Sepang 2 before Valentino Rossi and Jorge Lorenzo get their hands on the bike.

The official reasons given for the delay are that the GP15 and Yamaha’s gearbox are almost ready, but not quite, still needing a few last checks by the engineers before they are ready to be handed over to the factory riders.

Those of a cynical – or perhaps even paranoid – bent may be tempted to speculate that the delays are more to do with the media than the engineering. The first Sepang test this week is well-attended by journalists and photographers alike, the MotoGP press just as eager as the riders and the fans for the winter to be over.

The second Sepang test sees only a very few journalists attend, with few publications willing to spend the money to cover the expenses for what is often just more of the same.

Perhaps the factories have caught on to this, and are taking advantage of the opportunity to test important new parts with a little less media attention. Or perhaps it really is just a case of not being quite ready in time.

Despite the absence of the really big news, there will still be plenty to see. So who will be testing what, and what are the key factors to keep an eye on?

MotoGP: Yonny Hernandez Injures Shoulder in Training

01/23/2015 @ 12:01 pm, by David EmmettComments Off on MotoGP: Yonny Hernandez Injures Shoulder in Training

2014-Qatar-GP-MotoGP-Friday-Scott-Jones-18

Yonny Hernandez is to miss the first Sepang test. The Colombian rider crashed while riding dirt track, falling heavily on his left shoulder, and dislocating the shoulder. As a result, Hernandez will not be able to ride at Sepang, and will be replaced by Ducati’s test rider, Michele Pirro.

The good news for the Pramac Ducati rider is that the damage was mainly microfractures, and the ligaments and tendons were undamaged. The shoulder is a very complex joint, held together by a complicated network of tendons, cartilege and ligaments which allow it to move freely, but is vulnerable to damage.
