Fuel-injected, DOHC, four-valve-per-cylinder, 499cc parallel twin, liquid-cooled engine is horizontally mounted and performance engineered with forged pistons, carburized connecting rods and
ceramic-composite plated cylinders for plenty of tractable power. Also includes a horizontally opposed reciprocating balancer for uncommon smoothness.
Electronic fuel-injection system provides sure starts and excellent performance in virtually all conditions and altitudes.
Lubrication is via a semi-dry-sump system with an oil cooler for longer engine life.
Continuously variable transmission (CVT) connects engine power to the wet multiplate centrifugal clutch via a durable double cog-type rubber V-belt. Pivot coaxial drive shaft is used, allowing use of a
swingarm separate from the powerplant for excellent handling. Two-stage, adjustment-free silent chain system then transfers power to the rear wheel.
Muffler incorporates exhaust catalyst technology to reduce air pollution.
Fuel tank emission system includes a charcoal canister to control gasoline evaporation and reduce air pollution.
