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.


MULTI-POINT ELECTRONIC FUEL INJECTION

Independent fuel injectors are electronically controlled to deliver the precise amount of fuel for each individual cylinder for superior engine performance and maximum fuel economy.
