Yamaha TY250 R/Z 1991-99 Piston Kit
Please Note: This is a standard size piston kit to be used with a
standard bore size. If you want an oversize piston kit for a bore that has been
machined oversize, please
contact us
as we cannot possibly list all the available sizes here.
Oversize piston kits go up by increments of 0.25mm, so aside from standard we
normally have piston kits available at 0.25mm, 0.50mm, 0.75mm, 1.00mm, 1.25mm,
1.50mm, 1.75mm and 2.00mm oversize. Prox piston kits are a quality product, and are equal in quality to genuine, but at a fraction of the price.
They are made in the same factories as the genuine article and will have clearly marked " Made in Japan" on them. These pistons are 'cast pistons' and should not be compared with cheap Taiwanese low quality pistons. |
