Yosh GS700 # 289 ridden by K Schwantz

[oldschoolGS]

Hey guys, for anyone interested I just ran across a vintage cycle publication featuring the Yoshimura #289 bike ridden by Schwantz in 1985. The article was called "Pre-34" (as in Schwantz's later race number)

The machine was recently purchased by Brian O'Shea. O'Shea has in recent years aquired a nice collection of ex-AMA Superbikes and the #289 Yosh machine is one of his latest jewels.

Very nice article with lots of photos. Some interestings tidbits:

The bike used RG500 front suspension with what appeared to be 18in Dymag wheels (front and rear), and appeared to have a workable anti-dive system as well. In addition it had a hand made alum braced swingarm and 29mm smoothbores.

The article was long on photos but short on technical details.

I am sure one of the major US magazines will profile the machine in the future as several of O'Shea's other bikes have already been featured.

Happy Reading, Ed

Schwantz road that bike to a second place finish at Daytona in '85 even though Yamaha and Honda clearly had superior machines and Eddie Lawson and Freddie Spencer.

Britt Turkington raced an '83 750 up until '87 or '88 and would walk away from the pack until the thing would detonate. His engine builder, Kelly Roberts, was doing things like center boring the cams to lighten the valve train and all kinds of other stuff. Roberts had the distributorship for Cosworth at the time and having one-off pistons made up for Britt. I just happen to have a set of those little jewels I got from Britt.
