MotoCzysz (pronounced MOH-toh-chish) was an American motorcycle company based in Portland, Oregon that intended to compete in MotoGP.

[citation needed] MotoCzysz was founded by late American engineer and professional motorcycle racer Michael Czysz.

This race was the subject of the 2011 documentary Charge where the MotoCzysz team were referred to as the "swaggering American hotshots".

The 990 cc four-cylinder engine is mounted to the frame longitudinally, rather than transversely as on most similarly configured motorcycles.

For the 2007 MotoGP season, the Fédération Internationale de Motocyclisme (FIM) and Dorna Sports reduced the engine capacity to 800 cc for the class, rendering the C1's configuration ineligible for competition.

[citation needed] In the 2013 TT Zero Race, Rutter again won at a new record race-average speed of 109.675 mph,[16] with teammate Miller suffering breakdown.
