I am about to ruin your day, because I am going to show you something that you will want very badly, but can’t have. It is what happens when you have the best of both worlds. It is the two-wheeled version of having your cake and eating it too. This machine is called the Yamaprilia, and as the name implies, it is a mashup of the Yamaha RZ350 and the Aprilia RS250. Using the two-stroke, twin-cylinder engine from the RZ350, and the twin-spar aluminum chassis of the RS250, owner Gareth Evans is looking for the best of both worlds. The build is an interesting one – and is featured by our friends at BikeEXIF – as it involves Evans fabricating more than a few parts himself – something that is easier to do when you have a background in mechanical engineering, like Evans does.
I can imagine how the converstion between Wayno and Stevo went (well they are from Far North Queensland). That is Stephen Rothwell and Wayne Wright from The Two-Stroke Shop. It’s safe to say it ended with “Let’s build the bike that should have been”.
They set about getting a 500cc two-stroke built to slip into Apilia’s RS250 frame. The RS250 is an excellent bike. It’s good looking, has great handling and will stop on a dime. But! There’s always a but. In standard trim it’s powered by a Suzuki RGV250 engine. Not that the engine is all that lacking and can still scare most people, this bike with a 500cc 2-stroker now becomes a capable weapon ready to tackle modern 4-stroke sport bikes.
