So the 2008 Yamaha FZ1 Fazer has none of the annoying throttle snatch of the previous model. Unfortunately it's also lost some power; the previous model provided us with 138 horsepower stock; and the latest 2008 Yamaha FZ1 Fazer gives us 130 horsepower.
It's the same when you tune them: with Micron Serpent headers and Micron GP end can, a Power Commander and the secondary throttle valves removed a old Yamaha FZ1 Fazer made 148 horsepower. In exactly the same state of tune the latest bike makes 140 horsepower. So where are the 8 missing horses?
My guess, and it is just a guess, is Yamaha have slowed the rate of opening of the secondaries and modified fueling to improve off/on throttle transition. Getting that 8 horsepower back will probably involve swapping the ECU for the old model. We'll try it when we can get hold of one.
Still, the latest Yamaha FZ1 is a rollicking good ride, the pipe is too loud, really, even for uncivilized behaviors, but the bike is so wicked. Driving the Yamaha FZ1 Fazer made me grinning like a naughty schoolboy, having left a trail of cars spinning in our wake. Marvelous.
The Yamaha FZ1 Fazer, is probably Thailand's cheapest one liter bike, with its 998cc, 20-valve DOHC, in-line four engine it is a pleasure to drive and can really recommend buying one.
