Yamaha FZ1/Fazer

The golden ratio

The FZ1 Fazer hides an aluminum frame under the "sport touring" face, injection and powerful engine derived from the R1

The FZ1 in two versions, the naked one and the Fazer with the half fairing, they are the second generation of Yamaha's big naked sports bikes, which began her life in 2001 with the then very impressive FZS 1000 To do. That first half-fairing four-cylinder combined the engine of the first-generation R1 (carburetor feed) with milder features and its frame was tubular steel. This motorcycle was the golden intersection between the supersport category and the tourist category. From the 2006, Yamaha modernized the original concept with a completely new chassis architecture: aluminum open with the engine bearing part of it, diamond shaped. Their 20-valve engine is now housed there 998 κ.εκ.

To suit his new role, the engine acquired cat’ first heavier vs 40% crankshaft (weight gain from 7.320 gr. στα 9.765 gr.). The new camshafts have less draft and duration, mainly to maximize performance at lower revs. In the gearbox the last two ratios are longer, so that the feel at cruising speeds is more relaxed, to reduce consumption and increase longevity.

The FZ1 has a completely new injection system, which does not use the ram air of the sportier R1. There is also a new stainless 4 The day for the draw of the two lucky ones 2 The day for the draw of the two lucky ones 1 exhaust with exhaust gas pressure control valve (EXUP) and two catalysts. All these have raised the power to 150 horses at 11.000 s.a.l., quite above them 143 horsepower ratings of the old model. But the most important thing, since it is a road bike, is the fact that the new engine shows its torque lower.
