Engine Features

Lightweight 398cc, DOHC, liquid-cooled, dry-sump engine produces strong, usable low-rpm power.

Compact 4-valve cylinder head with 36mm intake valves, 29mm exhaust valves, narrow 28 included valve angle and shim-under-bucket valve adjustment system.

SCEM-plated cylinder (nickel-silicon-phosphorous) is lighter and more durable than an iron liner with excellent heat transfer properties.

Forged aluminum piston is 10% lighter than a cast piston and receives additional oil-cooling to the piston crown through a crankcase oil jet.

Compact 5-speed transmission utilizes a cable-operated clutch with separate outer cover for simplified clutch maintenance.

Additional weight savings with magnesium valve cover, clutch cover, and magneto cover.

Smooth throttle response with a MikuniT BSR36 CV-type carburetor fed by 6-liter airbox. The left side cover has quick-release fasteners for easy access to the air filter.

Electric start with lightweight starter motor and a compact 6.5 amp maintenance-free battery.

Automatic decompression system for quick/easy engine starts.

Thermostatically-controlled cooling fan mounted to the left radiator helps maintain consistent operating temperature in traffic.

Chassis Features

Compact digital instrument cluster with speedometer, odometer, twin-trip meters with addition/subtraction capability, clock, timer and stopwatch functions On-road legal lighting with bright 60/55 watt halogen headlight, compact tail/stoplight, lightweight, rubber-mounted turn signals and horn.

Narrow profile with smooth transitions between the tank, seat and bodywork Chrome-moly steel frame is torsionally strong with minimal weight. The backbone tube, front down tube, and steering head gussets form the dry-sump engine oil tank.

A bolt-on aluminum subframe helps reduce weight and simplify maintenance Chrome-moly steel footpegs, aluminum rims/hubs, plus engine guard and rear disc guard.
