Located in Menlo Park, California is a completely original 1978 Yamaha TZ250 with less than five miles. To quote the seller:
1978 Yamaha TZ 250, less than 5 break in miles if that .
This example has never even broken in. Garaged since new, will need new rubber & seals. Campagnolo 5-spoke alloys, fairing & duck-tail seat. Minor dings & scratches from sitting for so long, you will not find another one in nicer or newer condition.
Some information about 1978 TZ250s from Motor Bike Search Engine:
Introduced in 1978, the 'E' version of Yamaha's all-conquering TZ250 production racer featured a new chassis frame. Retaining the same 'monoshock' rear suspension layout (complete with adjustable pre-load and compression damping) as its forebears, it relocated the famous twin-cylinder, two-stroke water-cooled engine some 20mm further forward. Mounted on special alloy plates, this remarkable unit boasted Hitachi's automatically advancing / retarding CDI ignition system and Mikuni VM34SC carburetors. Reputed to develop 53bhp @ 10,500rpm, it was mated to a six-speed gearbox and reined in by front / rear disc brakes. A stepping stone in the careers of such riding greats as Kenny Roberts and Tom Herron etc, the TZ250's influence reverberates to this day.
The asking price is firmly set at $7,500. It would be nice to see this time machine cleaned up and on display--it would take some serious work to get it back to racing condition. See this fantastic barn-find on Craigslist here.
