We don't have a lot of extra detail on file for this specific listing beyond the part number and the oversize spec. If you're rebuilding a 650 twin and need to confirm bore size, ring gap, or compression height before you order, give us a call and we'll go over it with you.
The alias number 18-89304 refers to the same physical piston set, so if your parts book or an old invoice shows that number instead, you're looking at the same part.
