Kawasaki Ninja 300

Bit of a cheat from Kawasaki – the motor in this stretches back to the 1980s GPX250R, for goodness sake! The little Ninja is a twin, so thrives on revs, and it’s probably the smallest ‘proper bike’ around, with ZX-10R styling, boingy suspension, and decent brakes. They’re using them in the new Supersport 300 class in WSB too.
