JCC Triumph 650 piston set 9:1


We have found this 9:1 compression piston set to be more consistent in size and weight than A/E Hepolite pistons of the past. Each set of pistons we ship out is weight matched to +/- one gram, eliminating the hassle of having to balance your pistons yourself, or worse not checking at all.
Available in .020", .040", .060", and .080" oversizes (nominal bore 2.795")
Includes wrist pins and circlips, suitable for all 650 Triumph engines, pre unit and unit. For more information on installation see our tech pages.
