RING SET 500+.020 DEVES
A Deves +.020 oversize piston ring set for a 500cc engine.
This is a piston ring set for a 500cc application, machined to the +.020 oversize, made by Deves. Deves is a French ring maker that's long been used as a quality alternative to the original equipment ring sets on classic British engines, and this JRC part number is how our catalog carries that ring set.

The +.020 size means this set is meant for a bore that's already been taken out .020 over standard, so it pairs with a piston built to that same oversize. If you're rebuilding a top end and had the barrel bored, check what size your pistons actually are before ordering rings — the ring set has to match the piston size, not just the nominal displacement.
We don't have more detail on this one beyond the ring set description and size, so if you're not sure this is the right set for your motor, give us a call and we'll sort out the fitment before you order.
