Oops - the above wasn't quite accurate.

The 350F was 1979, the G was 1980 and the H, the last one, was 1981.

The G differed from the F only in small engine bearing changes, and the use of the new front forks from the 250G, larger in the stanchion diameter. Meant to help the front end patter, which arose from inadequate headstock gusseting (remember the frame breakages!)but it didn't really work.

Since 1982 was the last year of the 350 World Championship, the 350H of 1981 was identical to the G, and was the last Yamaha 350 TZ produced.

Wheels of all were 18 inchers.

BUT - check the frame!!!!!!!!!!!!!!!
