PISTON ASSY.T150 STD.
Standard-bore piston assembly for the Triumph T150 Trident triple.
This is a standard-size piston assembly for the T150 Trident triple, listed in the catalog as PISTON ASSY. T150 STD. It's a factory-standard bore piston, not an overbore or rework size, so it's the one you'd want if your cylinders haven't been sleeved or bored out.

Our catalog only shows this part appearing once, tied to a 1974 listing, so we don't have a lot of extra detail on file beyond what the description tells us. The figure references on this entry point toward carburetor-area listings in our records, which is likely just a filing quirk rather than anything about where the part actually lives - a piston assembly belongs in the top end of the engine, not the fuel system.
Give us a call before you order to confirm this is the right piston for your particular Trident's rebuild, since we don't have enough on file here to guarantee exact fitment beyond what's stated.
