Two-stroke engine internal combustion engine

A two-strokeengine is a type of internal combustion engine which completes a power cycle with two strokes of the piston during only one crankshaft revolution. This is in contrast to a "four-stroke engine", which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust functions occurring at the same time.

Air-cooled engine

Air-cooled engines rely on the circulation of air directly over hot parts of the engine to cool them.

Single-cylinder engine

A single-cylinder engine is a basic piston engine configuration of an internal combustion engine. It is often seen on motorcycles, auto rickshaws, motor scooters, mopeds, dirt bikes, go-karts, radio-controlled models, and has many uses in portable tools and garden machinery. Some single-cylinder automobiles and tractors have been produced, but are rare today due to developments in engine technology.

The front disc, and rear drum brakes, were operated pedal-cycle style by handle-bar levers and the machine also had oil pump reservoir lubrication, thus avoiding the need to pre-mix two-stroke engine oil. Electrics were 12 volt and it had both electric and primary-kick start and an automatic choke.

Starter (engine) electric motor used to start an internal combustion engine

A starter is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric, pneumatic, or hydraulic. In the case of very large engines, the starter can even be another internal-combustion engine.

Kick start motorcycle starting pedal

Kick start is a method of starting an internal combustion engine by pushing a ratcheting lever with one's foot. Kick start mechanisms were almost universally a part of motorcycle engines before the mid-1970s, and were phased out of production over the next twenty years or so as electric starters became standard equipment. There are still some motorcycles produced that have both kick and electric starters.

Other aspects included a dual seat, with locking under-seat storage, a storage pocket on the inside of the front fairing and a centre stand. A handlebar mounted binnacle forming part of the front upper bodywork contained basic instrumentation.
