Key features
Compact, lightweight: in-line 4-cylinder design is quiet, clean-burning and fuel efficient with yamaha’s famous durability.
16-valve double overhead cam: by using four valves per cylinder with 1 cam for the intake valves and 1 cam for the exhaust valves this dohc design efficiently exchange intake and exhaust gases for responsive power and fuel efficiency.
Direct drive: valves are activated through direct contact with the camshaft, for more precise valve timing control. Therefore rocker arms and their adjustment are eliminated for increased reliability and less maintenance.
