MCN overall verdict rating is 5

Kawasaki’s KR-1S was the quickest mass-produced, 250 two-stroke ever (139mph being recorded in a 1990 speed test), being quicker than both Suzuki’s RGV and even Aprilia’s later (but RGV-powered) RS250. On the downside it came with slightly questionable reliability and handling that could tank slap you into casualty. Dangerous, but hugely addictive.

In many ways you could be very mean and rate the Kawasaki KR-1S’s engine as poor. The preceding KR-1 suffered from iffy reliability, and KR-1S got nickel plated cylinders which are expensive to re-bore or replace. That said, if you service the engine regularly and use quality two-stroke oil, you have the quickest 250 two-stroke out there. 

Ride and Handling

MCN rating rating is 4

Again, the Kawasaki KR-1S is very ying-yang. On the one hand it’s very light, flickable and tiny, like riding a mini race bike. But on the flip side it’s capable of sending the bars into a mighty tank-slapper. The rear shock is on the soft side, and the suspension basic, and you were stuck with a 18inch rear wheel.  But once set up with a good steering damper the Kawasaki KR-1S was a flyer and rewarding to ride fast.

The Kawasaki KR-1S never had the mouth-watering appeal of the RGV or RS 250 from Aprilia which copied the lines of their 250GP bike relatives, so, looks-wise, the KR-1S is slightly disappointing. Nor are there any special parts, like the sculpted swing arm of the Suzuki or twin high race exhausts of the Priller. That said, the KR-1S’s brakes are not half bad. Compare and buy parts for the KR-1S in the MCN Shop.

Kawasaki’s KR-1Ss seem to be increasing in price consistently as good examples become rarer. Early models at less than £1500 might seem attractive but you’ll be buying problems. Instead, find a low mileage, well looked after, late model and it’s sure to go up in value. You’ll have a bargain, true mini race bike that can still cut it on track today, with a true two stroke race engine – just be sure to cover that clutch! Find a Kawasaki KR-1S for sale.
