MotoCzysz, one of the few American motorcycle companies to have designed, engineered, and manufactured their own internal combustion engine now stands alone with the addition of a proprietary electric motor.

MotoCzysz introduces the D1-10 D1g1tal Dr1ve, an electric motor specifically designed to power the highest performance electric motorcycles in the world. The D1-10 is the first D1g1tal Dr1ve in a line of new generation electric motors to meet the specific size and power requirements for the next generation motorcycle.

After 9 months of design, engineering, prototyping and testing, MotoCzysz recently completed a series of tests with the D1-10 and the results meet the performance target.

The D1-10 is a Liquid Cooled, IPM motor, with class leading torque density; 250+ft/lbs/320+Nm of torque, weighing less than 77lbs/35kg. (including mounting plates and pump)

The MotoCzysz D1-10 has a proprietary cooling system that allows the D1-10 motor to deliver a significantly higher percentage of peak torque over a longer period resulting in higher “real world” usable hp power from a smaller motor.

Note: The drive shaft was decoupled from the motor for this video, all the sound recorded is generated by the motor alone. In addition, the motor’s high RPM was creating some real dyno “instability”.

The first version MotoCzysz D1-10 generates over 100rwhp (rear wheel hp) which may not sound like much until you add the 250ft/lbs of torque to the equation. A current 2010 600cc sportbike makes 118hp (105+- rwhp) and 48 ft/lbs of torque at the crank, so the RWHP is right on target, the game changer is torque. Torque is the accelerative force; a motorcycle with more torque will out accelerate a motorcycle with less torque. Geared for the same top speed, we calculate our D1-10 motor will out accelerate a current 600cc in line four. The other “motor” benefit- the D1-10 delivered its power by converting 90% of the on board energy into torque, the 600cc in-line four- 35%.
