In Suzuki's words, "The king of sportbikes is back." Just when you think it can't get any better, it does. This liter bike breaks new ground with its "Broad Power System" (whose subtext is to broaden the appeal of sportbikes). When you think sportbike, you think of peaky power, high up the rev range, and not easy to use. Erase that thought. This all-new GSX-R engine has centrifugal variable valve timing (VVT) that shifts toward Harley-like torque at bottom revs, then progressively changes to sportbike timing at peak revs. Best of both worlds. The power compromise–either sacrificing bottom power to boost the top, or backing down peak power to fill out the middle–is broken by Suzuki Racing VVT.
