Our buddy Jamie Robinson snapped these pictures for us as Michael Rutter turned a wheel on the 2011 MotoCysz E1pc for the first time. Jamie reports that Rutter was “steady” at the test on the Isle of Man’s Jurby Airfield, likely taking it easy ahead of today’s practice session on the Mountain Course. Not only do these pictures give us a better look at the new bike, but they reveal one fascinating detail: inboard suspension for the front and rear.

Update: Michael Uhlarik explains the suspension.
Update 2: Michael Rutter averaged 90mph in his first practice lap this morning and hit 142mph through the Sulby speed trap.
Czysz locates the 200bhp electric motor in the space where the rear shock traditionally mounts. Relocating it under the tank helps centralize mass and make room for that motor. If you’re sitting on the bike, the left shock controls the rear suspension, the right shock the front.
The 2011 E1PC uses a simple pushrod and bell crank system to articulate the rear shock, which is mounted on the “tank.” The large diameter carbon fiber rod (pictured above, it’s wearing a yellow Race Tech sticker) on the left side of the rear tire is pushed directly by the rising rear swing arm, which gets translated from vertical to horizontal movement by a bell crank (which is basically a triangular pivot).
We tried this on the first full scale design mock up of the Amarok P1 (below), for the front end. See picture below. We ditched it in favor of using the space for electronics.

MotoCzysz hasn’t yet released full specs, but over the 2010 MotoCzysz E1pc it has these improvements:
50mm shorter wheelbase for quicker steering
better/ideal weight distribution
more rear wheel torque (up nearly 30% over 2010)
60% improvement in horsepower (nearly 200hp)
improved/extended torque curve (redline over 10,000rpm)
more energy on board (amount undisclosed)
reduced overall weight by over 25lbs (under 500lbs)
significantly overall higher efficiency (near 20% at 100 mph)
Michael expects that the bike will be more than capable of completing a 100mph average lap of the 36.6-mile road course. Something it could do as soon as today’s practice.
