Cooling System:Liquid Cooled
Lightweight & compact, 320cc, liquid-cooled, DOHC, 8-valves (4-valves/cyl), fuel injected, inline-twin cylinder engine. The engine has been designed to provide solid performance right across the rev range, with very linear throttle response, low vibration & excellent fuel economy.
Downdraft style, compact combustion chamber
4-valves per cylinder
straight intake path into the combustion chamber for excellent power output
4-valves per cylinder enhances the low to midrange torque
The YZF-R3 uses regular 87 octane gas
Intake valves are 26 mm in diameter & exhaust valves are 22.5 mm.
Isonite surface treatment on the valve stems for improved durability & wear resistance
valves feature carbon cutters on the valve stems to help reduce carbon build-up during slower speed operation
Valve adjustment interval is every 42,000 kms.
Automatic cam chain tensioner.
reduces mechanical engine noise & maintenance
Lightweight, all aluminum DiASil cylinder (die cast all aluminum cylinder with silicone content).
offers outstanding cooling performance / heat dissipation for consistent power delivery
reduces weight since there are no heavy liners & cylinder is made completely of aluminum
Offset cylinder design.
offsets the cylinder 7 mm relative to the crankshaft (to the exhaust side)
reduces frictional losses between the pistons & cylinder wall during the power stroke
improved power output & improved fuel economy
180 degree crankshaft with uneven firing order.
helps reduce “pumping losses” for maximum power output
provides an interesting exhaust note
Gear driven “primary coupled-force” balancer shaft.
reduces engine vibration for excellent rider comfort
