- reduce mechanical engine noise for a quiet, enjoyable ride
Intake & exhaust valves feature a special "carbon cutter" valve stem design.
- automatically removes carbon build up from the valve stems
- maintains maximum engine efficiency & power, even during extended slow speed use
- (carbon build up on valve stems can lead to sticky valves & poor performance)
Lightweight, aluminum cylinder features ceramic composite plating on the cylinder bore.
- insures uniform heat dissipation
- coating enhances the thin film of oil between the cylinder & piston, reducing friction & increasing power
Wet sump-type oil delivery system with centrifugal oil filtering system.
- automatically removes any particles found in the oil
Automatic cam chain tensioner.

24 mm, "closed loop" throttle body fuel injection system.
- excellent fuel economy & good throttle response
- 6 hole injector optimizes fuel atomization for strong, peppy power
- "closed loop system" uses an oxygen sensor to "sniff" spent exhaust & automatically adjusts the fuel / air ratio for reduced emissions
- fuel injection benefits include choke-free starting, steady idling during warm up, excellent fuel economy & reduced emissions
Easy access, dual stage, foam and paper-type air filter is used. Air box design reduces intake noise.
Fully automatic CVT transmission (CVT = constantly variable transmission).
- "twist-the-throttle-and-go" operation
- no clutch lever or gear shifting involved... the transmission is fully automatic.
Environmentally responsible exhaust system produces a very quiet exhaust note.
- muffler contains a honeycomb-style catalytic converter to reduce emissions
Air induction System (AIS) further reduces exhaust emissions.
- AIS system injects fresh air into the exhaust to ensure complete fuel combustion
- also helps to maximize the function of the catalytic converters
