The engine is always ready right off the throttle. If you grab a big handful of Mikuni the FZ1 picks up and dashes for the horizon. Hold them open and the engine responds by producing strong horsepower all the way to the obtrusive rev limiter. No surprise that the engine is a peach that revs hard and works like a terrier. It has all the lightweight internals of the R1, all the low-friction materials, and a super-compact design.
