Dragrace Concepts

We strongly believe that the Novarossi RX21WCS "Kangaroo" .21 motor is the ultimate drag racing motor available today. The 14mm crank has proven to turn more rpm and have better low end throttle response then 14.5mm crank motors. Litespeed Engineering has taken the "Kangaroo" to another level with its modifications. Based on extensive research and development to provide maximum usable horsepower. Litespeed Engine mods include, linner laping, head button adjustment for proper volume, super balencing of crankshaft, case relief, proper bearing fit, and timming adjustment for dragracing. Litespeed Engine Mods cooling head is included with purchase of motor. Hand laid ceramic bearings by Greg Settle are now available with purchase of motor. Hand laid bearings provide a tighter tolerance that can not be found in factory bearings. Ceramic balls are grade 3 roundness and are 59% lighter then steel balls. Increase RPM, decrease friction and crank play in your motor. Greg Settles ceramic bearings are run exclusivly by Dragrace Concepts.
