BSA 650 PISTON SET +060
A +060 oversize piston set for the BSA 650 twin, for engines rebored to that measurement.
This is a piston set for the BSA 650 twin, ground to the +060 oversize for a rebore. The description marks it plainly: BSA 650 PISTON SET +060, meaning it's meant to go into a cylinder that's already been taken out to that oversize measurement, not a standard-bore engine.

We don't have much more detail on file for this one beyond the oversize designation and the alternate part number it's also listed under. If you're rebuilding a BSA 650 top end and your machinist has already bored to +060, this is the piston set that matches that spec.
Give the shop a call before you order so we can confirm it's the right set for your particular engine and rebore before it ships.
