The 2012 SES TT Zero may not exactly be the talk of the TT paddock right now (Conor Cummins’ broken hand is still all the buzz here at the Isle of Man), but if you casually ask those familiar with one of motorcycling’s finest traditions, the Honda Mugen Shinden is a strong favorite to win this year’s premier electric motorcycle race.

You would be hard pressed to find either Mugen or Honda willing to admit Big Red’s involvement with the God of Electricity, as the name translates from Japanese, but it is clear that 17-time TT race winner John McGuinness will be climbing aboard a very competent machine later in this TT fortnight.

While Michael Czysz has been waxing poetic about the razor-like aerodynamical efficiencies the MotoCzysz team has been cooking up in the lab, and is ready to bring to the electric motorcycle racing table this year at the Isle of Man TT, Mugen has clearly chosen a counter-pointed melody with its brute force approach.

There is a good yin & yang dynamic brewing between the TT Zero’s two favored parties, but if the latest photos coming from McGuinness and Mugen can be believed, the Mugen Shinden is one beast of a machine.

With Honda’s electric motorcycle racing effort thinly disguised as the Mugen Shinden and getting a tremendous amount of attention, the motorcycle racing press missed the very subtle joint-entry by Zytek Automotive and Bournemouth Kawasaki Racing into the 2012 TT Zero. Already incorporating one of the most advanced technology groups in electric and hybrid automotive technology, as well as one of the top Isle of Man TT racing teams, the Kawasaki-Zytek ZX10ev race bike also benefits from another important element: the backing of Kawasaki Motors UK.

Using one of Zytek’s 100 kW (134 hp) permanent magnet oil-cooled KERS motors for its power plant, the Kawasaki-Zytek ZX10ev has the added benefit of a six-speed gearbox, which like the bike’s chassis, is a recycled component from the Kawasaki Ninja ZX-10R donor bike the electric racer is built from. Using the firm’s automotive racing experience to its benefit, Zytek’s motor design has previously been used on the company’s Hybrid Le-Mans 24 hour race-winning car, and uses technology similar to Zytek KERS system used in the 2009 Formula 1 Championship.

Powering the motor will be four 15Ah LiFeP04 cylindrical cell battery packs, which have been located in the ZX-10R’s fuel tank, airbox, radiator, & exhaust for a total of 11.8 kWh in energy storage. “The shape of the Ninja ZX-10R frame is designed to curve around a conventional engine, and does not lend itself naturally to the fitment of a battery,” said Zytek Project Manager Des Hill. “We have ended up filling the area normally use by the tank, air-box, radiator and exhaust with four sculpted packs. In total we have 240 power cells carefully distributed around the bike.”

Retaining the same basic shape as last year’s bike, the 2012 Brammo Empulse RR is still a looker, due mainly to its very “Iconic” livery scheme. Keeping things an Oregonian affair, the addition of Portland-based Icon as a sponsor to the Brammo racing effort bodes well for the team, and brings more validity to the budding electric motorcycle racing scene. It’s just a shame the color scheme lasted all of a few hours for Team Icon Brammo at Sears Point Raceway this weekend.

Crashing in yesterday’s first TTXGP practice session, Steve Atlas was diagnosed with six fractured vertebrae. With a thrashed bike, the Brammo squad managed to cobble together the race bike again, and thanks to its busy black & white design, one could barely see the black gaffer tape and white electrical tape that was keeping things together. Now with 130 hp at the rear wheel, as well as 35 lbs less poundage on its bulk, the revised Empulse RR clearly has a problem with people named Steve, as the electric motorcycle once again bucked a rider off, also again in Turn 7 at Sears Point.

Highsiding Steve Rapp during Saturday’s qualifying session, it is not clear what caused the rear wheel of the Empulse RR to spool up, as Rapp said he was still straight up and down with the bike when he went airborn. With fluid dripping from the bike afterwards, and Rapp stopping a lap earlier or two earlier because of the bike cutting out, the Brammo team is surely still pouring over the data as we type. That effort will do little to change the fact that Rapp has likely broken his hand from the incident, and will be out of racing the rest of the weekend, much to the chagrin to the Attack Performance AMA Superbike team, which Rapp took to a sixth place finish that same day in Superbike Race 1.

As you can see from the photos after the jump, the damage does not look too extensive to the bike — though, our assessment is only skin deep. Two riders, two highsides, one corner…no bueno. Surely not the result the Ashland-based crew wanted before it launches the street-bike version of the Brammo Empulse on Tuesday next week, it’s not clear if Brammo will try and race tomorrow, or if they even can race sans a healthy rider who lapped during Saturday’s qualifying.

The first North American TTXGP round is this weekend, piggybacking off AMA Pro Racing’s stop at Infineon RacewaySears Point. Lightning has been quietly putting in impressive lap times this year. On the #80 bike is veteran Banana rider Michael Barnes, whose 1’47 lap times would place him in the back third of the AMA Supersport class this weekend. Meanwhile on the #89 bike is WERA top-man Tim Hunt, who has had the dubious task of learning Sears Point on a 240hp machine. Hunt’s times have been seven to eight seconds off Barnes, though were ahead of Rapp’s before his crash.

While Lightning has shown considerably more polish than in past rounds, the team has had its own setbacks with reliability, including one incident which saw the chain adjuster bolts on the Lightning Mk. II sheer apart, dropping the chain off the sprocket, and locking up the rear wheel of Barney’s bike. Barnes was not pleased with this, but fared better than the two Steve’s on-board the 2012 Brammo Empulse RR.

Brammo is back for electric motorcycle racing in the North American TTXGP series, as the Ashland-based company is set to defend it’s #1 plate this year with Steve Atlas on board ( Shelina Moreda is slated to join the team later in the season). Gaining a title sponsorship from Icon, Brammo arrived at Infineon Raceway Sears Point with some edgy graphics on the 2012 Brammo Empulse RR. Dropping roughly 35 lbs in weight, and gaining roughly 50hp over the bike they ran at last year’s season opener, Brammo is making most of those gains in its revised motor and power inverter for the newest Empulse RR.

The chassis is noticeably the same to last year’s bike, and sans some minor improvements here and there, the bike is technically very similar to last year’s lap-record setter. Unlike the Brammo Empulse R that will debut Tuesday next week, the Empulse RR does not use the six-speed IET gearbox. Brammo’s Brian Wismann explained to A&R that the high-voltage system that the Empulse RR uses does not benefit as much from the IET gearbox as the lower voltage street bike does, and thus hasn’t made it to the race bike…yet.

With these pictures taken just a couple hours before Steve Atlas had a highside crash at Sears Point, we imagine the 2012 Brammo Empulse RR doesn’t look as good as when we last saw it. Atlas took a pretty big hit, but is said to be ok (UPDATE: Atlas has six fractured vertebrae, and will be out for the weekend). The bike on the other hand…well, hopefully the Brammo crew can get it ready in time for this weekend’s two TTXGP races in wine country. More drool material after the jump.

The Isle of Man TT sent out an interesting press release yesterday, where it cited the largest competitor entry list in the TT Zero’s race history (lawyer’s crafty word choice note: this does not include when in 2009 the race was run under the TTXGP banner and 23 competitors allegedly entered). With 18 competitors signed up for the single-lap electric motorcycle race around the Mountain Course, we can surely expect the field to dwindle, as virtually none of the electric series have been able translate large entry lists into large starting grids, sans maybe the FIM e-Power race at Laguna Seca, which TTXGP is now piggy-backing off of as well.

Announcing the return of MotoCzysz and its two-rider team of Mark Miller and Michael Rutter, the Isle of Man TT also gave a nod to the Mugen entry, which is widely believed to be a front for Honda’s own electric motorcycle racing program. Having 17-time TT race winner, and long-time factory Honda rider John McGuinness at the helm of the Mugen Shinden has only added further credence to the rumor. However getting only one sentence in the press release was perhaps the most intriguing entry to the list of competitors: Bournemouth Kawasaki/Zytek Automotive, which will race the team’s Kawasaki-Zytek ZX10ev race bike.

For 2012, Segway returns as the title sponsor for MotoCzysz’s electric motorcycle racing program, with the team’s first race set to be the TT Zero event at the Isle of Man TT. Continuing the special sauce that lead MotoCzysz to a 1-2 victory at the Isle, Segway Racing hopes to be the first and fastest team to crack the 100 mph average lap speed barrier for electrics on the Mountain Course.

Rumored to be bringing another all-new 2012 MotoCzysz E1pc to the iconic road race, MotoCzysz’s biggest competition will come from a now more-developed Lightning “Flying Banana” and wild card Honda Mugen Shinden. Further entrant announcements are still expected as well.

Right after it was made official that John McGuinness would race in the 2012 TT Zero on the Mugen Shinden, the 17-time Isle of Man TT race winner was whisked off to Motegi to test the electric superbike. McGuinness’s involvement with Mugen’s racing effort has only added further credence to the notion that the team is a front for Honda’s foray into full-size electric motorcycles (Mugen was also started by Hirotoshi Honda, the son to Honda founder Soichiro Honda).

Debuting the Honda RC-E concept last year, A&R has also heard reports that the Japanese OEM has been playing with electric motorcycles in various forms for almost a decade now. Despite continued reports that the Mugen Shinden is a rebadged Honda RC-E, the two bikes share almost no similarities, except of course for this whole running on electricity thing.

Thought to be a Honda in disguise, the Mugen Shinden (神電) broke cover this weekend at the 50th anniversary celebration of the Suzuka Circuit. While the Shinden leaves a bit to be desired visually when compared to the Honda RC-E concept that debuted at the Tokyo Motor Show, underneath the bland white fairings is a carbon fiber chassis with 122 hp on tap, and a curb weight of 573 lbs. With that much weight on board, Mugen’s electric superbike is sure to have a massive battery pack, which should give MotoCzysz, Lightning, and other 2012 TT Zero contenders a run for their money…the £10,000 that is still up for grabs to the first team to crack a 100 mph lap.

Piloting the Mugen Shinden around the 37.733 mile TT course will be none other than “King of the Mountain” John McGuinness. The seventeen-time TT race winner has been keen on racing the electrics for some time now, and his involvement with the Mugen squad only adds more credibility to the belief that Honda is using the tuning outfit as a front to race its electric in a low-pressure situation (McGuinness is a contract Honda rider with the Honda TT Legends squad). Interviewed at the Morecambe Football Club, McGuinness added even more linkage between the two Japanese companies when he refered to the project as the “Mugen/Honda” electric bike.

UPDATE: Added more information & technical specifications from Mugen’s press release.

This morning we learned that John McGuinness will be Mugen’s rider in the team’s bid to break the 100 mph barrier at the 2012 TT Zero. Heavily speculated to be a stealth project by Honda (無限 / Mugen was started by Hirotoshi Honda, the son to Honda founder Soichiro Honda), much speculation has been done over what sort of bike Mugen would be bringing to the Isle of Man TT, and now we have that answer.

Called Shinden (神電), meaning “God of Electricity” in Japanese, the machine may not have the same exquisite lines of the Honda RC-E electric superbike concept, but upon closer inspection, Mugen’s electric race bike seems like a wolf in sheep’s clothing. Breaking cover at a press conference in Suzuka, the Mugen Shinden features a brushless three-phase 90 kW (120hp) DC motor, carbon fiber swingarm, and a carbon fiber twin-spar frame design.
