PISTON, MSS/VENOM +.040
A +.040 oversize piston for the Velocette MSS and Venom, used when reboring a worn cylinder.
PN · MAS97/30
This is a piston listed for the MSS and Venom, both Velocette models, not a Triumph part. The +.040 designation means it's an oversize piston, ground .040 inch over standard, the kind of thing you'd spec for a rebore on a cylinder that's worn past standard tolerances.
