Very few motorcycles offer the experiences you get from riding a two-stroke bike when it improves its playing and sends that blue smoke out the tailpipe. The exhaust seems to release a sense of urgency that few other motorcycles can match. In theory, two-stroke bikes are more efficient than four-stroke bikes because they have a burst of power with every turn.
Comparatively, the two-stroke engine can produce the same horsepower, if not more, at a significantly lower rpm.
Today, amid tighter emissions regulations, the two-stroke is like an island in an ever-expanding ocean. Over the past few decades it has grown so small that many cyclists have no experience of what it feels like to ride one.
However, both strokes have a special place in history, having dominated the 500cc Grand Prix races of the mid-1970s with the legendary Giacomo Agostini, until the turn of the century, when Valentino Rossi won the last world championship. 500cc the a Honda NSR500. Every two-wheeler should know about these powerful two-stroke sports motorcycles that have graced our roads and race tracks.

The 145kg motorcycle was fitted with a liquid-cooled 500cc two-stroke V-twin engine producing 110 hp.
Like many two-stroke bikes, the V Due is dead because of emission limits. Bimota used their direct fuel injection technology to make the V-Due road viable, but failed to impress and caused trouble. The V-Due could have changed the fate of the two-stroke motorcycle if it had worked.
