Nissin ABS Brake Defect Creates Waves of Recalls for OEMs

By 3 Comments

A wave of recalls are reaching the shores of motorcycle manufacturers, as brake maker Nissin has had to recall a number of its ABS units for a misaligned inlet valve, which could allow foregin particles into the fluid of the braking system, which could cause the ABS functionality to fail.

Triumph first discovered the defect, and reported it to Nissin, which in-turn notified its other affected OEMs. So far  5,766 motorcycles have been affected by the recall, comprising a total of four manufacturers (a list of the models is after the jump, with a link to the appropriate NHTSA posting). We will update this list if/when more model recalls are announced.

Rotary-Mounted Cam + Motorcycle Gymkhana = Awesome

By 10 Comments

Motorcycle gymkhana is perhaps the ultimate test of any road racer’s bike control. Navigating machines through courses of curves and cones, it boggles even this veteran rider’s mind at the level of precision that goes into every maneuver, and every video of these special events is a free tutorial on the benefits of smooth throttle, brake, and clutch actuation.

It’s not like we need a real good reason to post up today’s installment, but someone finally figured out that a counterbalanced rotary video rig would be an awesome point-of-view perspective for this form of two-wheeled racing.

After the jump, we ride with the winner of this year’s Dunlop Autoby Cup, Round 3 — though, this might be one of those few videos where you’ll want to mute the sound, and play your own soundtrack. You’ll see what we mean…

Video Highlights of the 2013 Suzuka 8 Hours

By 7 Comments

In case you missed watching this year’s Suzuka 8 Hours (the second stop on the FIM Endurance World Championship calendar), and that is pretty much everyone outside of Japan, since no live stream was available on race day, we’ve got you covered.

Compressing eight hours of hard-fought endurance racing into four and a half minutes, you can witness Ryuichi Kiyonari’s nasty crash on the F.C.C. TSR Honda, Schwantz’s epic return to road racing, and the victory of MuSASHI RT HARC-PRO Honda with Leon Haslam, Takumi Takahashi, and Michael Van Der Mark on-board.

Is Aprilia Looking for Concessions to Join MotoGP Factories?

By 21 Comments

The performance of Aleix Espargaro and Randy de Puniet has made it clear that Aprilia’s ART machine is the bike to be on for any rider not on a factory or satellite machine. There are a lot of reasons for the bike’s success: the engine in its standard state is very strong, the bike handles exceptionally well, and is very easy to ride.

But perhaps the biggest advantage which the Aprilia has is the use of Aprilia’s WSBK-derived electronics package, which is helping to make the bike extremely competitive. “Electronics are 75% of the bike,” Aleix Espargaro said in a recent interview with the Dutch MOTOR Magazine.

And here lies Aprilia’s dilemma. From 2014, Aprilia will be forced to choose. If they wish to continue as a non-factory entry (as the category replacing the CRT will be called), they must use the Dorna-supplied spec-software, written by Magneti Marelli for the spec-ECU.

Though the spec-electronics has made huge bounds in the six months since it was introduced, it is still very much a project under development. However, Aprilia’s software is a proven package, with many years of development behind it.

Up-Close with the 2013 Honda RC213V

By 35 Comments

The Honda RC213V and its predecessors have always been formidable machines in MotoGP, but for 2013 HRC has truly managed to make a peerless motorcycles for its four riders: Dani Pedrosa, Marc Marquez, Stefan Bradl, and Alvaro Bautista.

In the past, the Honda was all about its motor and its ability to rocket out of the corners, whereas the Yamaha YZR-M1 was more about its chassis and the ability to have supreme edge-grip through the turns.

This dichotmy created two bikes that required two very different riding styles to be fully utilized; and also it meant sometimes the Honda was the weapon of choice, and sometimes the Yamaha was the better tool for the job — depending on the track, of course.

But all that changed this past season and a half. Finding a solution to the RC213V’s chatter problem (a problem that was courtesy of the raised minimum weight requirement for 2012), in the latter part of last season, HRC watch Dani Pedrosa storm after Jorge Lorenzo in the Championship points.

Helping the Repsol Honda rider was of course HRC’s seamless shifting gearbox, which at some tracks on the calendar is good for a tenth or two per lap, but what really spurred on Pedrosa was engineers at Honda overcoming the one weakness in the RC213V’s design.

No longer was the race between a bike with power and the other with handling — now the Honda had both; and better yet, Yamaha had no reply for this development.

While Yamaha Racing is still hoping to debut its own seamless gearbox during the 2013 season, it will likely do little to change the course of events in the Championship standings. The 2013 Honda RC213V is a matchless machine right now, and it is the hands of two very formidable riders.

Don’t count Jorge Lorenzo and his Yamaha YZR-M1 out of course, but the reigning World Champion has more than hisfill when it comes to fending off the two Repsol Honda riders.

Making it a point to capture this fine machine in detail at the Red Bull US GP at Laguna Seca, I dodged bikes in the very busy MotoGP pit lane to bring you a bevy of high-resolution photos of the 2013 Honda RC213V MotoGP race bike, which are waiting for you after the jump (be sure to check-out my similar photo sets of the Ducati Desmosedici GP13 and Yamaha YZR-M1 from Austin, TX as well).

MotoGP’s New Rules on ECUs & Factory Riders Explained

By 12 Comments

There was a small flurry of excitement when the minutes of the last meeting of the Grand Prix Commission, including rules on the spec-ECU and factory entries were announced last week. That was then followed by a bout of confusion, as everyone tried to figure out what all of the various changes meant, and what impact they may have on the series. It appears that the answer to that question is “not as much as you might think,” so let us take a look at what has changed.

Kevin Schwantz & Team Kagayama Podium at Suzuka

By 9 Comments

Seeing the return of American racing legend Kevin Schwantz to FIM road racing, the 2013 Coca-Cola Zero Suzuka 8 Hours endurance race was certainly one to remember.

While the return of Schwantz overshadowed many of the other big names in the sport that competed in the event, not to mention the former World Champion’s own teammates: Noriyuki Haga & Yukio Kagayama, the Suzuka starting grid was also blessed with the entries of Jonathan Rea, Leon Haslam, Josh Brookes, John McGuinness, Michael Rutter, Simon Andrews, and American Jason Pridmore.

Though a long eight-our race, the on-course action was surprisingly close, with the Top 5 teams on the same lap well past the three-hour mark. Team Kagayama was in good shape for a solid result from the onset of the race, as Noriyuka Haga put the team’s Suzuki GSX-R1000 in a solid fourth position.

The team rose as high as second-position with Team Manager Yukio Kagayama on-board, as the Suzuka specialist kept a solid pace, and benefited from the pit stops of other teams, not to mention the retirement of the FCC TSR Honda team, which had a race-ending crash with Ryuichi Kiyonari at the helm.

While the crash from Kiyonari on the FCC TSR Honda dashed the race-win-repeat hopes of World Superbike’s Jonathan Rea, Kevin Schwantz finally dazzled fans in the third hour as he took to the course. For all the postulation that the 49-year-old was over the hill for the Suzuka 8 Hours, the Texan held his own on the Kagayama Suzuki, and managed to keep Team Kagayama in the podium hunt, especially as other top teams succumbed to the rigors of endurance racing.

MotoGP: FIM Confirms New Rules for Factory/Non-Factory Spec-Electronics, Engine, Fuel, & Entries for 2014

By 11 Comments

We have already extensively reported the coming rule changes for the 2014 MotoGP Championship season (most recently the conclusion of the engine claiming rule), so the news today is really more about the FIM has giving its blessing to the new direction that Dorna is taking for the premier class.

Drawing a new distinction now as to how teams are classified as “factory” entries, and thus subject to differing fuel, engine, and entry requirements, the real crux of the equation revolves around whether a team uses the the spec-electronics software from Dorna, or decides to use its own software (note: all teams will be on a spec-ECU from 2014 forth).

Thinking of Off-Roading a Ducati Hypermotard SP?

By 18 Comments

When a press bike shows up at your doorstep, the miles on the odometer betray the sights and stories the bike could tell about its relatively short existence thus far.

At just nearly 2,000 miles, our little Ducati Hypermotard SP in the normal world would have stories of high-fives at the Ducatisti bike nights, hours spent in the parking lot outside of the local Starbucks, and maybe some tall tales of a wheelie or two.

But sort of on-par with dog-years, press-bike miles act as a multiplying factor, when in regards to the maturing of the machine. So with our machine at 2,000 miles, well that’s a bike that has really been around the block. Burnt clutches, blown fork seals, and chewed-up tires — those all likely describe this little SP’s first stop on the magazine tour bus, so multiply accordingly dear reader.

It is rare though that you really get to see/hear what the machine has gone through before it gets to you, but a quick check of the license plate in the video after the jump confirms that this “pretty impressive machine” has found its way into our hands. As far as we can tell so far, the description fits.

Ride with John McGuinness at Suzuka

By 4 Comments

The pinnacle of two-wheeled motorsport, as far as the Japanese are concerned, is the Coca-Cola Zero Suzuka 8 Hours endurance race on the Endurance World Championship calendar.

Immensely popular with the fans and fielded with a bevy of expert local teams, even the Japanese OEMs take the Suzuka 8 Hours very seriously — and are not above stacking their factory squads with the top riders from various national and international road racing series.

One such team at Suzuka is the Honda TT Legends crew, which as the name implies, is made up of legends from the Isle of Man TT: John McGuinness, Michael Rutter, and Simon Andrews. Backed by Honda Europe, McPint & crew are on some top machinery, but as they have already seen in qualifying, that’s only part of the battle.

With Rutter and Andrews having never ridden at Suzuka before, the team has a steep learning curve, though over the eight-hour race, we think they will have plenty of time to crawl back from their 29th spot qualifying, and into their Top 10 goal. Racing kicks off Sunday at 11:30am local (JST), but until then enjoy this on-board footage and witty banter from Mr. TT.
