At a time when Japanese manufacturers were getting increasingly aggressive and race-oriented with their 400s to compete in their domestic Formula 3 championship, Yamaha introduced the FZR400 in 1986 as a bike to be enjoyed “on twisty public roads where the customers would actually be riding and enjoying them.” The US got it in 1988, and many riders preferred it over the bigger brother FZR600.
For more on the FZR400, check out this excellent profile on Yamaha’s site where they talk about the challenges of it being the first motorcycle to use “full-fledged radial tires” and how they fought the urge to implement quick steering like their competition to create something that consumers would enjoy more on the street.
Previously owned by an amateur racer and shop owner, this particular example has been lightly modified, turning the stock machine into a track-ready specimen that retains its road-legal status.
Manufactured in September of 1988, this example is VIN: JYA3BFE07KA009239
The dash has been flipped 180°, the tachometer and temperature gauge have been rotated, and the speedometer, odometer, and warning light cluster have been removed. Because there is no longer an odometer on this bike, its true milage is unknown.
