3XV Yamaha TZR250 balance shaft RC Sugo

3XV Yamaha TZR250 'RC Sugo race kit' balance shaft 1991-95 models - a very rare item. The standard balance shaft is rough cast and made to a budget, the race kit shaft is thinner, lighter and the end weight is welded, rather than simply a press fit. These things matter when your tuned track / race bike revs harder and spins up quicker. Standard shaft weighs 604 grams vs RC Sugo kit shaft 494 grams. We can also supply the balance shaft gear set with these - price is an additional £45 (confirm by email, so we know you want them).
