Motorcycle fans the world over have been waiting for the release of the 2010 F4.It's always a dicey proposition to make sweeping changes to a highly-regarded superbike – just ask Ducati, which found that truth out the hard way with the 2003 999 – so it's not particularly surprising that the new bike is instantly recognizable as an F4, though the entire engine and chassis have been completely redesigned for more performance. Overall weight is down by 22 pounds, and the radial-valve, inline-four engine puts out 186 horsepower, a 12-horse gain over the 2009 model.
A Marelli 7BM ECU controls (among other things) the eight fuel injectors, variable-length intake manifolds and traction control, and it also offers multiple Sport and Rain engine control maps. Spent exhaust gases exit via the four expected underseat outlets, but those "organ pipes" are now squared-off instead of round. Suspension bits include a fully adjustable inverted 50mm Marzocchi up front and a remote reservoir rear shock from Sachs. Naturally, Brembo monobloc calipers clamp down on dual 320mm front discs, which are joined by a single Nissan four-piston caliper and 220mm disc out back.
