449cc liquid-cooled, DOHC, four-valve, four-stroke single
- A lightweight forged piston reduces reciprocating weight
- Triple piston rings and a 21mm diameter piston pin help increase durability and reduce necessary maintenance
- Lightweight titanium valves and aluminum valve spring retainers reduce reciprocating weight and boost high-rpm reliability
- Asymmetrical high-acceleration cams yield high intake efficiency
- Lightweight high-performance titanium exhaust header contributes to low and mid-range throttle response
- Electric starting facilitates quicker stall recovery and lowers rider fatigue
- Large-volume airbox contributes to both intake efficiency and sharp engine response. An air duct fashioned from polyethylene resists deformation caused by intake pulses and helps ensure stable engine performance
- Advanced engine tuning provides a broad torque curve and an optimized power delivery for quick acceleration without excessive wheelspin
Digital Fuel Injection (DFI)
- 32-bit digital fuel injection system with a 42mm throttle body
- System measures coolant temperature, air intake temperature, air intake pressure, engine speed and throttle position, then automatically delivers the ideal amount of fuel to optimize power delivery
- Crisp engine response is especially advantageous for instant acceleration after landing from jumps
- Promotes trouble-free starting
-a great benefit in races with engine off starts
- Fuel injection allows the use of a lighter throttle return spring, which reduce rider fatigue
Transmission
- The five-speed (one-down, four-up) manual transmission locates the reverse gear below first
- Actuating the reverse-lock release lever when in first gear allows you to shift “down” into reverse
- Compact reverse-lock release lever can be activated with the right thumb, allowing the reverse gear to be engaged while still keeping the front brake lever depressed
- The combined weight of the reverse gear system and the lightweight aluminum chassis is no heavier than using a steel frame without reverse |
