Kawasaki have released the first social media teasers for a new two-stroke motorcycle on its way to the UK soon.
The news has already sent the internet rumour mill into overdrive, with early speculative reports suggesting that it may feature a completely new engine, complete with fuel injection, or forced induction, or even a camshaft and accompanying valve arrangement to mechanically regulate inlet and exhaust flow.
Unfortunately for fans hoping to see this come to fruition, such an ambitious engineering effort for what would ultimately prove to be a niche product seems unlikely to happen – although Kawasaki remain tight-lipped on exactly what it will be.

Instead, the new model is more likely to mark the return of the Japanese brand’s KX250 motocrosser – with natural aspiration and conventional porting.

Last seen in 2008, this off-road only model would reintroduce full-size two-strokes to the marque’s line-up, which currently only features four-strokes in both their motocross and enduro range – excluding super-minis, 85s and 65s aimed at youth riders.
If the radical mechanical reports do prove to be true, they would mark a significant shift from traditional two-stroke motors, which rely on port timing and pressure dynamics rather than valves.

With a traditional setup, the piston’s movement directs the flow of air and fuel. As it moves down during the power stroke, the piston compresses the mixture in the crankcase, pushing it through the transfer port and into the cylinder.
At the same time, in a process called scavenging, the exhaust port opens to release burnt gases, and the fresh mixture rushes in to take its place.
