Predecessor of KR1/S.

The engine design is close to the racing KR which ran at late 1970s. It has a unique mixture of rotary valve and reed valve for induction. Notable as a production bike that uses tandem (Front-Rear) cylinder placement. It has twin crankshaft, and a strange combination of 16in fr. wheel and 18in rear wheel. It does not have power valve so torque&power is a bit low compare to new comer (ie, RGV). 2-stroke. 14km/L, 185km/hr
The KR-1 and KR1S models are not LAMS approved.
