The 2019 Isle of Man TT once again saw the record lap drop for the electric class, with the new TT Zero record mark set at 121.909 mph by Michael Rutter, on the Mugen Shinden Hachi machine.

The Japanese squad has become a tour de force at the Isle of Man TT, taking now six-straight victories on the Mountain Course. Each year, we have seen the winning TT Zero lap time drop in number, and 2019 was no different...though barely.

Shaving less than a second off his time from 2018, Rutter crossed the line in 18'34.172" - a figure likely attributable to the dismal weather conditions for this year's TT gathering, which meant very little practice time for all the competitors.

Despite that lack of progress, a quick look at the Mugen Shinden Hachi shows that the Japanese outfit has not been resting on its laurels, despite the lacking arrival of a serious competitor in the TT Zero class.

Another debut from the Tokyo Motorcycle Show, the next iteration of the Mugen Shinden has debuted and its ready for the Isle of Man TT.

The bike is officially dubbed the Mugen Shinden Hachi – and for those who don’t know, “hachi” means “eight” in Japanese, with this being the eighth iteration of the Mugen Shinden electric superbike.

On the spec sheet, we see that nothing has changed on the 2019 bike versus the Mugen Shinden Nana that raced last year. But, a quick visual inspection sees that the Japanese tuning brand has been busy optimizing its aerodynamics package.

As such, the front intake for the Shinden Hachi has been revised. The tail section has also been reworked, and looks a bit more slippery.

Take a good long look at it, because here is the electric motorcycle that is going to win this year’s TT Zero race at the Isle of Man TT.

That might seem like a presumptuous thing to say, but with Mugen fielding a three-rider lineup, and no real competition coming out of the woodwork, it would be hard to imagine a different result.

The question of course is which riders will be onboard the Mugen Shinden Nana when it takes the #1 position? John McGuinness? Bruce Anstey? Or, Lee Johnston?

Your guess is as good as ours, as all three road-racers are more than capable of putting down a race-winning lap on the Mugen.

We are still about three weeks away from the official unveiling of the Mugen Shinden Nana, the seventh iteration of the Isle of Man TT winning electric superbike, but news is starting to trickle in about this racing effort.

In case you didn’t know, Mugen is looking to make the 2018 Isle of Man TT its fifth-straight victory at the iconic road race, and the chances are very good of that result happening.

This is because with scant competition coming from the other race teams, Mugen is set to race itself again this year, but for 2018 it will be with not one, not two, but three riders on the grid for this year’s TT Zero race, as the company confirmed via Twitter.

Lost in a story about testing for this year's TT Zero, the all electric motorcycle race on the Isle of Man, was an image that portends great things for the future of long-range, high-speed battery-powered biking.

A trick learned from two giants: the Boeing 787 and the Humpback whale.

2009 was a watershed year for motorcycling. Globally sales of new bikes vaporized, forcing the giants to shut plants and kill brands.

The major brands, like Honda, Yamaha, Suzuki and Kawasaki all pared down to the bare minimum, while European brands clung to life by their fingernails. In America, Harley-Davidson quietly asked for a loan.

But 2009 was also a touch-point for the modern electric vehicle. Tesla unveiled its first car; governments invested billions to support EV development; and the TTXGP, the world's first all-electric motorsport event was held at the historic Isle of Man TT.

Within five years, street-legal electric motorcycles were commercially available and the annual TT Zero race (as it was called after 2010) became the place to watch the amazing potential of battery-powered vehicle technology.

In Japanese, “roku” is how you say the sixth ordinal, which means the electric superbike you see above, the Mugen Shinden Roku, is the Japanese firm’s sixth entry into the Isle of Man TT.

Piloted this year by John McGuinness and Guy Martin, the expectation is that the Mugen Shinden Roku will be the first electic motorcycle to do a 120 mph lap (from a standing start, no less) at the TT – a barrier that was nearly broken last year.

Team Mugen has progressed rapidly each year it enters the TT Zero class at the Isle of Man, and for 2017 they once again are bringing a new machine to the starting line at Glencrutchery Road.

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).

The Isle of Man TT is still two months away, but Team Mugen is looking ready to make it a three-peat in the TT Zero electric race. Mugen’s 2016 bike is called the Shinden Go, and while “go” might be Japanese for “five” the name is very appropriate for the electric superbike.

Many expect Mugen to break the 120 mph lap barrier at the Isle of Man TT, especially since John McGuinness came extremely close to the mark last year, with a 119.279 mph lap.

Caught testing in Japan this month, here are our first glimpses of the Mugen Shinden Go, with test rider Hikaru Miyagi on-board at the Tsukuba Circuit (above) and Sodegaura Forest Raceway (photos after the jump).

Development for properly fast electric racing motorcycles has fallen onto the shoulders of one brand: Team Mugen, and the Japanese firm has confirmed that it will continue to push boundaries at the Isle of Man TT this year.

Confirming this week that it would race the 2016 Isle of Man TT, in the SES TT Zero electric race, Mugen also announced the return of its two-rider team of John McGuinness and Bruce Anstey.

In addition to that news, Mugen formerly divulged the fifth edition of its electric superbike, called the Shinden Go  – in case you haven’t caught onto Mugen’s naming scheme, “go” is “five” in Japanese.

A bit of a formality, since rider John McGuinness already spilled the beans in December last year, but Team Mugen has confirmed its entry into the 2015 Isle of Man TT.

Mugen will have a new bike at the contest, named the Shinden Yon, “Yon” being “four” in Japanese, and the bike being the company’s fourth TT racer — like its lap times, Mugen’s engineers are very consitent with their naming conventions.

Little is known about the Shinden Yon, and Mugen is saying only that the machine is “newly developed to improve over last year’s model.
