- extended cylinder service life
-
Flat top, lightweight forged aluminum pistons.
- less reciprocating mass for fast engine response
- reduced mechanical vibration for excellent reliability
-

-
Wet sump lubrication system with easy access, spin on oil filter & drain plug for easy oil changes.
-
Classic side mounted 2.3 litre air box houses an easy access, a high-flow viscous paper-type filter.
-
"Closed loop", dual bore, 35 mm throttle body fuel injection system with linear throttle response for easy riding.
- system uses throttle position sensor (TPS) to help optimize intake air flow & power
- ISC or idle speed controller ensures a steady idle
- 4 - hole injectors optimize fuel atomization & feature a dual spray pattern for more complete combustion chamber filling
- "closed loop system" uses an oxygen sensor to "sniff" spent exhaust & automatically adjust the fuel / air ratio for reduced emissions
- oxygen sensor is located before the mufflers, so the use of aftermarket "slip-on" mufflers will not affect the closed loop system
- fuel injection benefits include; excellent throttle response, choke-free starting, steady idling during warm up, excellent fuel economy & reduced emissions
-
Smooth-shifting, 5-speed transmission.
- optimized gear ratios match engine power for strong acceleration
- 5th gear offers reduced engine rpms at highway speeds
- clutch is an "outer pull" design for light, easy lever effort
-
Special narrow design belt drive final drive.
- narrow 21 mm wide belt design
- cleaner & quieter than chain drive... no messy chain splatter
- low maintenance... no regular adjustments or lubrication required
- belt drive system simplifies customization
-
Maintenance-free transistor controlled ignition (TCI).
- produces a strong spark for fast starts
- provides precise ignition timing / mapping for optimum engine performance at all rpms
-
2 into 1 exhaust system.
- large diameter header pipes for maximum flow
- dual stage muffler produces a low, throaty V-Twin growl
- heat shields protect rider & passenger from hot components
- 3-way honeycomb catalyzer reduces harmful exhaust emissions
-
Air Injection System injects fresh air into exhaust ports to fully burn any unburnt fuel, further reducing exhaust emissions.
