RING SET T140 750 +.020 HEPOLITE (Same as BSA A65 +.060)
Hepolite +.020 oversize piston ring set for the T140 750 twin, also used at +.060 on the BSA A65.
This is a Hepolite piston ring set for the T140 750 twin, ground to +.020 over standard bore. The catalog lists it as R26490-020 under the older reference form, same physical set as what's sold today under JRC 750R/020. Worth noting for anyone cross-shopping BSA parts bins: this same ring set is used on the BSA A65 at their +.060 oversize, so don't be surprised if you see it turn up under a BSA listing too.

Ring sets like this get fitted when a bore has been taken out to that specific oversize during a rebuild, so before ordering confirm your barrels have actually been bored to +.020 on the Triumph side. We don't have further detail on this one beyond what's in the books, so if you're unsure which oversize you're dealing with, call the shop and we'll help you sort it out before you order.
