Like a well set-up race bike, it carves through corners with minimal effort, making it the best-handling F4 ever. It’s also the first production bike to be fitted with an auto-blipper, which lets you change down through the gears without having to use the clutch. But while it handles superbly and dishes up searing acceleration and mind-jangling top speed, the power delivery has too many flat spots and the throttle connection isn’t as predictable as its rivals. It’s an electrifying experience, but a handful to ride very fast. In fact, the F4 has been a fixture on race circuits since it was introduced, both as a trackday weapon and in many race series.
