The Mugen Shinden Go has officially dropped in Japan, showing us the Japanese outfit’s fifth evolution of the Isle of Man TT electric superbike.

As we reported earlier, the Shinden Go comes with obvious changes to the fairing design, though likely there are further enhancements underneath its skin.

To our eye, the Shinden Go looks to have smaller frontal cross-section than bikes of the past, and there are noticeable changes to the race bike’s carbon fiber chassis, which now looks to be of a monocoque design. The carbon fiber swingarm design has also been changed.

Additionally, Mugen says that the rear suspension is a “cross link rocker” design, which has been developed specifically for the Shinden Go.

Of course, the biggest change people will be talking about is the 10kW power increase, which brings the Mugen Shinden Go’s peak horsepower figure up to 161hp. Weight remains at 550 lbs, with peak torque down to 154 lbs•ft (from 162.24 lbs•ft).
