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.

Thursday Summary at Assen: Races Saved & Races Changed

06/25/2015 @ 6:20 pm, by David Emmett2 COMMENTS

2015, MotoGP, TT Circuit Assen, The Dutch TT, FP1

If the Honda is so bad, why are two RC213Vs at the top of the timesheets? That seems like a very valid question, given the public struggles that all of the Honda riders have had with the bike this year. Has the 2014 chassis finally fixed the Honda’s ailments? Is Márquez back?

If only it were that simple. Firstly, of course, Marc Márquez never went away. The double world champion still possesses a gargantuan talent, and the desire and will to use it. He was hampered by many aspects of the 2015 bike, including both the engine and the chassis.

The 2015 chassis, he explained at Assen, was more precise and could be used more accurately. Unfortunately, the only way to get the best out of it was to ride it like every lap was a qualifying lap. That level of intensity is just not sustainable over race distance.

At some point, you will make a mistake, and the 2015 chassis punishes mistakes mercilessly. So HRC have reverted to a hybrid version, using a 2014 chassis and the new swingarm which Márquez first tested at Le Mans.

MotoGP: Dutch TT Moved to Sunday for 2016 & Onward

06/25/2015 @ 1:22 pm, by David Emmett2 COMMENTS

2015, MotoGP, TT Circuit Assen, The Dutch TT, FP1

The Dutch round of MotoGP, the Dutch TT at Assen, is to switch from Saturday to Sunday.

From 2016, the event will surrender its unique status as the only MotoGP round to be held on Saturday, and fall in line with the rest of the MotoGP races. It will, however, remain on the last weekend of June, but will now be on the last Sunday, rather than the last Saturday of June.

The decision was taken by the circuit management after long consideration and discussions with many of the parties who have an interest in the race.

The circuit also commissioned market research into the use of leisure time among the Dutch public, which showed that Sunday is the day most people set aside to spend attending sporting events, such as the Dutch TT.

Circuit director Peter Oosterbaan and chairman Arjan Bos said that the market they were operating in was such that Sunday was a better day all round for sporting events.

Preview of the Dutch TT: To the Great Natural Tracks

06/24/2015 @ 5:10 pm, by David Emmett1 COMMENT

assen-track-map

Assen is a funny old track. And when I say old, I mean old, the event has been on the calendar since 1925, though back then there was no such thing as world championship, and the race took place between Rolde, Borger and Schoonloo, some ten kilometers east of Assen.

From 1926, it moved to a route between the villages of De Haar, Oude Tol, Hooghalen, Laaghalen and Laaghalerveen. The roads, forced into short straights with fast sweeping kinks and bends by the complex drainage patterns of the creeks and ditches which keep the region from reverting back to peat bogs, gave shape to the track which was to follow.

They still leave their mark on the circuit today, despite being a closed-circuit since 1955, though the track has been much shortened since then.

What remains is a track with nary a straight piece of asphalt on it. The back straight meanders between the Strubben hairpin and the fast right and long left of the Ruskenhoek, living up to its name of Veenslang, or Peat Snake.

The short stretches between the fast combinations of corners weave and flow, and the only thing keeping the front straight straight is the pit wall. As a piece of geometric design, it is a disaster.

As a race track, it is glorious, proving that the best tracks are not designed on paper, but laid out in a landscape. Mugello, Phillip Island, Assen: all great riders track, each owing a debt of gratitude to the landscape which forms them.

MotoGP: Van Der Mark Will Not Replace Abraham at Assen

06/23/2015 @ 12:07 pm, by David Emmett4 COMMENTS

michael-van-der-mark-wbsk-misano-pata-honda

Michael van der Mark will now not be racing at his home MotoGP round of Assen. The deal to replace the injured Karel Abraham at the AB MotoRacing team has fallen through, the stumbling block being who would cover the cost of crash parts.

The deal came very close to fruition. Rumors that Van der Mark would take the place of Abraham first started over the weekend at Misano, emerging publicly on Monday afternoon.

HRC had put Van der Mark forward to replace the injured Abraham, and the AB MotoRacing team were very open to having the young Dutchman as a substitute.

Things soured on Monday, however, as discussions grew heated over who would pay for crash damage to the Open class Honda RC213V-RS if Van der Mark were to drop the bike.

Michael Van Der Mark Making His MotoGP Debut at Assen?

UPDATE: And it’s off again – Van Der Mark will not be replacing Abraham at Assen after all

Michael van der Mark looks set to make his MotoGP debut at Assen this weekend.

The 22-year-old Dutchman will be swapping his Pata Honda CBR1000RR World Superbike machine for the Open class Honda RC213V-RS of the AB MotoRacing team, where he is set to fill in for the injured Karel Abraham.

Abraham badly injured his foot, severly dislocating his toe, in a fall during FP4 in Barcelona.

Rumors that the Dutchman would get the chance to race a MotoGP machine at his home race started circulating in the Dutch media earlier on Monday.

Several sources close to the situation confirmed that the deal was very close to being sealed. There are just a few final details to be settled, including matters such as covering the cost of damage in case of a crash.

Living the Dream – A Photographer Story: Catalunya & Assen

07/09/2014 @ 6:58 pm, by Tony Goldsmith10 COMMENTS

living-the-dream-catalunya-assen-motogp-tony-goldsmith-17

Sitting down to write about Catalunya has proven difficult. As far as Grand Prix weekends go, it went without a hitch.

I did have a minor problem with the GPS when I arrived in Barcelona. I entered the coordinates to my hotel and it came up with an address in Zaragoza 5 hours away. After a brief moment of panic, I came up with an ingenious idea. Why not try inputting the address, that did the trick.

For most of the grand prix I’ve covered this year, I’ve been fortunate enough to get a photographers vest. Having a vest gets me on the grid on race day, which provides a good opportunity for portraits of the riders, particularly as the tension starts to build.

Shooting the grid does however pose the question of where to shoot the race. If you have a scooter it’s not an issue. As I don’t have one, I have to plan ahead and either shoot around the start area or take my chances with the shuttle bus.

At Catalunya I didn’t have a vest, which therefore gave me a little more freedom to pick my location for the race. Also the layout of the track enabled me to go to several locations and get back for the podium without having to rely on the shuttle or cover too much ground on foot.

MotoGP: Assen Pit Stop Analysis – Who Won & Who Lost?

Friday-Assen-MotoGP-2014-Dutch-TT-Tony-Goldsmisth-01

With the win at Assen, Marc Marquez brought his tally for the season up to eight, and a clean sweep of the races so far. After the race, many fans remarked on Marquez’s remarkable pit swap strategy, jumping straight from one bike to the other without touching the ground, rather than hopping off one and onto the second bike, as the other riders on the grid do.

It looks spectacular in photos, such as this one tweeted by Marquez himself, though if you watch the video from MotoGP’s Youtube channel, it’s clearly more of a hop than a leap.

Did Marquez get any benefit from it? The best way to answer that is to measure it, and fortunately, the MotoGP.com website offers us two ways to do that. The results section of the website holds a PDF with an analysis of every lap done by each rider, broken down into sector times.

By taking the times posted by each rider for the last sector of the lap on which they entered the pits, and the first sector of the lap on which they exited the pits, we get a clear idea of how much time riders lost in swapping bikes.

In addition, the video of the race on the MotoGP.com website (MotoGP.com subscription required) shows on-screen the times riders actually spent in the pits, from crossing the pit lane entrance line to the pit lane exit line. Using these two numbers, we can get a fair idea of who comes out best after making their pit stops.

Saturday Summary at Assen: Of Tire Gambles, The Wisdom of Thinking for Yourself, And Lorenzo’s Fear

A veritable galaxy of stars may have lined up on the grid for the 84th Dutch TT at Assen, but the real stars of the show were the elements. After the rain wreaked havoc on qualifying, shaking up the grid, it was back on Saturday for two of the three races.

Riders and teams were forced to rethink their strategy, make decisions quickly, and gamble on tires and the weather. It made for intriguing races, rather than sheer thrills like the MotoGP race at Barcelona.

Changing conditions offered the brave and the smart opportunities, and mercilessly punished anyone who got it wrong. You felt for the 45 minutes of the races that anything could happen.
