IOMTT: Anstey Laps 112 MPH on the Mugen Shinden San

06/02/2014 @ 4:41 am, by Jensen Beeler8 COMMENTS


When it comes to single-lap speed, Bruce Anstey is the man at the Isle of Man this year. Setting the outright fastest lap ever around the Snaefell Mountain Course, on the last lap of the Dainese Superbike TT no less, Anstey has another record to be proud of at the 2014 Isle of Man TT: the fastest TT lap ever on an electric motorcycle, at 112.355 mph unofficial.

For those not keeping up with the TT Zero news, Bruce Anstey is playing teammate to John McGuinness on Team Mugen. The Japanese tuning brand has brought its third-generation electric superbike to the TT, appropriately calling the 500+ lbs behemoth the Mugen Shinden San (san meaning “three” in Japanese).

Mugen is heavily favored to win the TT Zero race this year, as rival MotoCzysz has bowed out of this year’s competition, while Michael Czysz wages his own battle against a personal illness.

This leaves the two Mugen machines as likely to provide the main on-track action, with Anstey already proving capable of giving McGuinness stern competition. McPint has had a tough outing so far this TT, and has admitted to being off the pace. Putting in a disappointing 7th place finish during the Superbike TT, McGuinness will be keen to find the top podium step in the other solo-classes.

With Monday hosting the second night of TT Zero qualifying/practice, Anstey’s lap is likely not to last long in the record books, as Mugen is slowly dialing up the speed on the Shinden San. The Japanese team has made no secret about targeting a 115 mph lap, which would put the electrics on par with the 650cc twins in the Lightweight TT class.

While that mark is still a bit off from the 132 mph lap Anstery managed on his Honda CBR1000RR SP, it is impressive to note the pace that the top electric teams have shown over the years — with each passing TT giving way to an additional ~5 mph around the Mountain Course.

If teams like Mugen can maintain that rate of development, it could mean only be a few more years until we start talking about an electric superbike holding the outright lap record at the Isle of Man TT…now that’s something to chew on.

  • NEVER underestimate the ingenuity of racers.. but I would be shocked if electrics were challenging the outright fastest lap time in a few years. They need probably double the current onboard energy and similar weights as the top-tier gas bikes to challenge them directly.

    In practice, McGuinness turned in a 109 mph average speed lap despite a 40 second stop to reset his bike.

    The TT Zero race should be coming up in a few hours .. looking forward to it.

  • TT race is Wednesday, no? I believe tonight is another qualifying session.

  • Frenchie

    And now after the 3rd qualifying they’re already over 115 mph!

    Bike is basically the same just playing around with weights and getting better at how much power vs longevity.

    Sorry but no tech advances just more experience

  • Right, looks like the schedule got pushed back for rain. Race is scheduled for Wednesday now, last I heard.

    “Just more experience” doesn’t explain a 13 mph gain from 2012 to 2014; McGuinness is not an inexperienced racer. The 2012, 2013, and 2014 bikes are significantly different (powertrain, battery configurations, aero, weight).

  • Race was always scheduled for Wednesday. Each race day is followed by a practice/qualifying day, for buffer since weather is so common.

    There were big changes from the 2012 bike, but 2013 to 2014 has only changes to the internals (same chassis/weight, but 10hp more).

    It’s not like Mission has been sitting around twiddling their thumbs during all this time.

  • Was Mugen running a Mission powertrain in 2013?

    I thought there were also some aero tweaks from 2013.

  • That’s what my spies tell me.

    I should clarify my above, big changes from 2012 to 2013, internal changes 2013 to 2014.
