In describing the Yamaha FZ1, it would be inconceivable to start anywhere other than the motor, which in case you haven't had it pounded into your head yet, is based on the R1 powerplant. The 998cc Inline-Four motor achieves its displacement courtesy of a 77mm bore, 53.6mm stroke and utilizes the pre-2007 R1's 20-valve (five-valve-per-cylinder) configuration. On the dyno the FZ1 flexed its juice-free four-cylinder muscle by taking top honors in peak horsepower with an impressive 129.3 at 11,500 rpm and second-place in the torque courtesy of a bulging 66.2 lb-ft at 9,500 rpm. The FZ1 means serious business in a Clark Kent sort of way.
