Kawasaki KR-1

The KR1S life story is as brief and spectacular as the Kawasaki's powerband.

Launched in spring '90 (only a year after Kawasaki surprised everyone, especially Suzuki, with their RGV-eating KR-1), the completely redesigned KRl-S quickly established itself as a winner on the street and track. Two years later it was finished; no longer imported and soundly beaten by RGVs everywhere. The KR1-S took razor steering and insane power-to-weight ratios a stage further than anyone had before. Tall gearing pushes it past 130mph and makes it still lOmph faster than even the latest RGVs.

The KR1-S handling experience is a combination of light weight, instant steering, and overdamped suspension which adds up to superb racetrack manners and massive tankslappers on real roads. KR1-S natural habitat, where slappers, an explosive powerband and whippet handling make the Kawasaki a high-adrenaline handful. Dual carriageways and motorways don't overwhelm the KRl-S. It's cruise at 80mph on the bottom edge of its powerband for as long as the tank lasts (90-110 miles), and do it in relative comfort thanks to a roomier riding position than the RGV. More important to impoverished teenagers in the early '90s was the price: in '91 a new KRl-S cost £3,779—£311

The 250 Kawasaki did everything you might expect of a 50bhp machine which weighs 271 lb. It was significantly quicker than the RGVand the 1990, KR-1 S version has been uprated to give more power still — enough to make it some 5mph faster.
