Where the previous bike boasted 106bhp from its 675cc engine, the new S version cranks out 111bhp, the R manages 116bhp and the new RS manages 121bhp. The extra capacity and performance comes courtesy of a new crankshaft and increased bore and stroke, fitted to all versions of the bike. In European markets there’s also a smaller 660cc version that’s able to be restricted to just 47bhp and meet ‘A2’ licensing laws for new riders. In line with new European rules, all the versions have ABS brakes meet Euro4 emissions limits, which came into force on January 1st this year. Partly as a response to the changes needed to reduce emissions, all versions of the bike get ride-by-wire throttles. They also feature traction control and multiple riding modes.
