Robin Tuluie, who once used to work with Polaris and who’s now with the Renault F1 team, has come up with this unique motorcycle – the Tularis 800 – which two-stroke fanatics should love. The bike is fitted with a two-stroke, 772cc parallel-twin (taken off a Polaris snowmobile!) that produces a massive 183 horsepower at 8,700rpm. With a measured 161bhp at the rear wheel and a dry weight of 119 kilos, you can probably imagine what the performance is going to be like…

While the engine is from Polaris, the Tularis’ chassis is a custom-built unit that makes liberal use of materials like carbon fiber, magnesium and aluminum. Öhlins suspension components are used at both ends. With a better power-to-weight ratio than some 1990s 500cc GP racebikes, the Tularis 800 should certainly be an insane ride…
