This 1988 Yamaha FZR400 is claimed to be a one-owner bike that’s been garaged since new. The seller adds that there’s just over 2,600 miles on the odometer, and that the original manuals, spare keys, and a few uninstalled performance parts will be included. A strong aluminum “Deltabox” frame, well-tuned suspension, light weight, and a high-revving, 65 HP 399cc liquid-cooled four made the model memorable, and as they never sold in huge numbers here in the displacement-obsessed North American market, they’re always a special sight. Find this one here on eBay in Whitehall, Pennsylvania for $7,500 OBO.
Full-faired 80’s sportsbikes tend to be either very good looking or very awkward, and we’ve always thought these Fizzers fell easily into the former category. This one appears to be in fine shape, with clean fairings, good paint, and tidy looking aluminum components, though there is some yellowing of what looks like a protective finish applied to the frame. Color-matched tri-spoke wheels utilize dual discs up front, while a preload-adjustable mono shock resides under the rider.
No fairing-off engine or frame shots are provided, but we do get a nice closeup of the cockpit, The odometer mirrors the seller’s claims, and gauges look super-clear and crisp with simple white lettering on a black background–no fussy LED bar graphs needed. Some worn paint on the brake fluid reservoir is the only nitpick we can muster.
The liquid-cooled, transverse four employs twin cams and breathes through a quartet of Mikuni carbs, delivering ~65 HP to the rear wheel via a 6-speed gearbox. The model was known for being a screamer (note the 14k RPM redline), and there are plenty of reports of riders taking the little four past 15,000. Hopefully the uninstalled “period performance parts” include a Yoshimura exhaust.
