They have tubular steel frames and modified YZF-R1 engines which are carbureted. The models were virtually unchanged over this period, except for colour options, the introduction of the FZSS which had a black engine, and in some European countries the models were fitted with rudimentary catalytic converters. The main changes included a new chassis, suspension, bodywork and a completely different engine. Cast aluminum diecast diamond-shaped frame with the engine as stressed member replaced the older tubular steel frame along with a control-filled die-cast swingarm. This brought the bike up to date with modern rivals.
Like early R1s the first generation carburetted FZ1 was completely dominated by the muscular mid-range urge of that game changing powerplant. Despite detuning for its nakedbike chassis the FZ1 still had massive grunt. From Yamaha fitted the updated fuel-injected engine from the R1. It did get better suspension and brakes but the grunt was less raw with fuel injection and, for me at least, that did take away some of the appeal that the carburettor fed original was endowed with. To get some of that animal back the first thing I would do before even taking delivery of an FZ1 is get the dealer to change the gearing.
Yamaha presses its advance into the mid-size sportbike market with a two-prong attack in the form of the FZ Naked and simple, this smallest FZ sibling brings a good balance of features to the table, and it can serve as an entry-level bike of sorts. Back to Yamaha Yamaha FZ. Yamaha FZ Generations:.
Big valves and high-lift cams flow plenty of air. But is that enough to make the FZ1 the perfect liter-class naked bike? I'd been slightly annoyed when, with about 25 miles of the afternoon's route still to cover, the FZ1's digital fuel gauge began to flash. Having left my South African cash in the hotel, I'd have to slow my pace to avoid running out of gas before finishing the loop. But after easing back the revs, short-shifting instead of chasing the tacho needle across the dial and slowing my cornering speed on the wonderfully twisty coastal roads southeast of Cape Town, I was surprised to find myself enjoying the ride more rather than less.
