Similar to past iterations, the Go is based around a uniquely-shaped monocoque frame, its carbon fiber body stickered up with the established Mugen Shinden theme. The motor, a 120-kW (160.9-horsepower) oil-cooled affair, offers up 10 more kilowatts (13.41 hp) than last year's unit, but is down 10 Nm (7.38 pound-feet) of torque, at 210 Nm (154.89 pound-feet) peak. It also appears to be positioned a little further back than in previous years, nestled in just below where the cross link rocker rear suspension attaches to the new swingarm.

Battery specifics, beyond the mention of its laminate-type lithium-ion nature and 370 volt output go unmentioned in the official press release. We imagine the capacity is increased over last year, though it's interesting to note that the 250-kg (551.2-pound) weight is unchanged. Speaking of weight, if returning rider John McGuinness has lost the 22-lbs set as a goal in return for a Shinden for his collection, it will certainly help in the effort to set yet another electric record for the Mountain Course. And, move the best battery-powered bikes closer to the bar set by the traditional machines.
As with 2015, Mugen will bring two copies of the latest bike – one for each of its riders, the aforementioned McGuinness, along with the returning Bruce Anstey – to the TT Zero, which is currently scheduled for the 3rd of June. While the Shinden Go might not make spectator's teeth rattle as it whizzes past, it does have its own particular wail. You can catch a preview of its banshee scream by clicking on the video above.
MUGEN (M-TEC Co., Ltd., President: Tomoyuki Hashimoto) today unveils a brand new machine, "SHINDEN Go" to participate in this year's Isle of Man TT Zero race.
Major parts including battery system, motor, and frame on the new machine have all been newly developed, reflecting knowledge gained through the races of the past four years.
Alongside the improved output of the power systems, battery and motor, the cooling system has also been improved in order to access the increased power.
A monocoque type frame is chosen for optimum lightness and stiffness, and to improve the aerodynamics, while at the same time permitting the battery to be positioned inside the frame.
Cross link rocker rear suspension, designed and manufactured by M-Tec, is adopted to make space for the huge battery, helping to improve the machine's responsiveness.
John McGuinness, who has won at the Isle of Man TT event 23 times, and was champion of the TT Zero and superbike Senior TT class last year (Time: 17 mins 03.567 secs, Ave.: 132.701mph = 213.516km/h), and Bruce Anstey, who has a total of 10 TT victories, including a maiden superbike race win last year, are nominated in the team's attempt to win the race for a third successive year.
