The SRViper is a proven, reliable performer in the 125HP class. Sleek, aerodynamic lines are reflected in its second-generation body work. The naturally aspirated 1,049cc engine delivers plenty of torque for superb throttle response. Power delivery is silky smooth and rider ergonomics are state-of-the-art. The SRViper—like all Yamaha four-strokes—is extremely fuel efficient, clean and reliable. Engineered for the long run.
