This is like no in-line-four cylinder sportsbike ever produced. It’s simply sensational. The Yamaha R1’s ultra-short-stroke engine has a cross-plane crankshaft, with its crank pins set at 90° and has irregular firing intervals, which is technology lifted directly from Valentino Rossi’s factory YZR-M1. At a standstill the motor spins up like a two-stroke and on the move the R1’s ability to accelerate, no matter where you are in the revs is astonishing. Thanks to the clever engine design it grunts off corners like a V-twin, while giving superb feel through the rear tyre, and howls along straights like the mad, bad in-line-four it really is. Best of all it sounds just like Rossi’s M1 at full chat. Watch the Yamaha R1 video test.
