When I started riding 250 2 strokes and 4 cylinder 4 strokes with sky-high rev limits were the go-to thing. From the mid 90’s all the Japanese manufacturers stopped making them in favour of cheaper-to-produce and friendlier-to-learners single or parallel cylinder 250’s. Now thanks to Kawwasaki it looks like they might make a comeback.
My GSXR250RR revved to 17,000rpm, and I think that was the lowest of the manufacturers. It was also my first adventure bike, taking me up 90 mile beach among other places.
