    Hi all I have a 1984 TC510 project bike that was rebuilt back @ 10/15 years ago and now needs rings. it has a 94mm bore and the piston is "Ross375" marked on it. Any idea if some one is selling these pistons?
    I am thinking the piston is a special batch that was made back in the day....

    Usually pistons for 510 TE are from 91.5 to 92.5 or 93.

    Those were probably custom made by Ross Racing pistons in El Segundo, CA. The company is still in business and makes both motorcycle and automotive pistons.
