Just picked up a used speed four, it was actually a trade down from an old zxr750 so as the speed is a modern bike, theres not much trade off top end, but the acceleration of the four blows the old kwak out the water. bikes got a lovely mid-range that just wants to pull all the way to the redline, but is just as good in 6th potterin round. it handles like a dream, you can just throw it down into anything because you know you can trust the chassis and the incredible stopping power of the brakes. look past the looks which you either love or you hate personally i think it looks so unique that you have to love it. It is truely an amazing package, take one out and give one a try I promise blast some b roads and you'll want to hand over the cash!!! Strengths: Chassis, brakes, engine. Weaknesses: Looks bit 'unique' for most middle of the road/fashion following people.
