2017 Suzuki GSX-R1000R Overview – Video
At its core, the engineers totally redesigned the GSX-R engine with a goal of increasing top-end horsepower, without losing any low- to mid- range performance. They did so, claiming that horsepower increased from 189.9 to 199.27 in the Euro-spec form. The most noticeable new feature being the Suzuki Racing Variable Valve Timing (SR-VVT) system which was adopted from the manufacturer’s MotoGP efforts. The system uses a simple small device that is attached to the outside of the intake cam where centrifugal force pushes steel balls along grooves to rotate the sprocket and retard intake valve timing at a specific rpm, this results in additional power at high rpms.
