Yamaha FZ6 600 2004 — Specifications

In 2004, Yamaha decided to play a bold hand in the mid-displacement roadster market. Facing the Honda Hornet, Suzuki SV, and Kawasaki Z750 that dominated sales, the tuning fork manufacturer drew its Yamaha FZ6 600, a stripped-down version of the Fazer S. The gamble was clear: take the R6's four-cylinder engine, bolt it into a brand-new cast aluminum frame, ditch the fairing, and fit an aggressive round headlight vaguely reminiscent of the MV Agusta Brutale. On paper, the recipe had plenty of appeal. In practice, the picture was a bit more nuanced.

On the engine side, the Yamaha FZ6 delivers 98 horsepower at 12,000 rpm with 62.8 Nm of torque at 10,000 rpm. Figures that immediately betray its sportbike heritage. This fuel-injected 600 cc unit, with its 12.2:1 compression ratio and 4 valves per cylinder, only comes alive in the upper rev range. Below 6,000 rpm, the engine purrs politely but offers little push. The usable powerband truly kicks in at 8,000 rpm, and that's where everything changes. The four-cylinder wakes up with infectious aggression, the exhaust note climbs in pitch, and throttle response becomes sharp all the way to the redline. It's exhilarating, but you have to accept wringing the engine out to extract every last drop of performance. Riders accustomed to low-end torque — those coming from a twin or a big single — may find it disconcerting.

The chassis more than makes up for this mechanical demand. At 180 kg dry, with wide roadster handlebars and a 43 mm telehydraulic fork, the FZ6 proves precise and playful through a string of corners. The rolling chassis inspires confidence from the very first miles. Braking, handled by twin 298 mm front discs clamped by four-piston calipers, delivers respectable stopping power for the era. The 120/70 and 180/55 tires on 17-inch rims provide solid grip and allow for spirited runs on twisty roads. The 795 mm seat height makes it accessible to most rider builds, which makes it a sensible machine for a motorcyclist racking up their first few seasons.

Against the Kawasaki Z750, the confrontation is direct but unbalanced on one specific point: torque. With its extra 150 cc, the green machine offers significantly better engine flexibility in everyday riding. In the city, on main roads, and when getting back on the throttle out of corners, the Z750 is far more forgiving of a lazy right wrist. The FZ6 demands more involvement, more gear changes through its six-speed gearbox, more work in the upper reaches of the tachometer. It's a riding philosophy. Those who love making a four-cylinder sing will find their reward. Those who want fat midrange torque should look elsewhere.

Priced at 6,860 euros at launch, the Yamaha FZ6 600 remains a solid bet on the used market today. The question of an FZ6's price in France obviously depends on the model year and condition: 2005-2006 versions can be found at very reasonable prices, and the S2 version introduced in 2007 addressed some early shortcomings. Reviews of the FZ6 generally converge on the same verdict: a reliable, well-finished motorcycle that's pleasant on long trips thanks to its 19.4-liter tank, but one that demands a rider willing to push it to fully enjoy the experience. Neither a pure sportbike nor a comfortable tourer, it occupies a clever middle ground that has won over thousands of riders. A roadster with character — provided you enjoy chasing the redline.
