Triumph BSA Billet Aluminum Inspection Plug Set 57-2166 Oddball Euro Parts Construction entirely of stainless steel

Construction entirely of stainless steel

Works VERY well with the clutch/brake lever kit shown elsewhere in the store

most historical books dealing with old European motorcycles are pretty lousy

to suit most larger machines of the 50s and early 60s such as Gold Star and A10 650

Triumph BSA Billet Aluminum Inspection Plug Set 57-2166 Oddball Euro Parts Construction entirely of stainless steelMagically lovely. CNC machined and polished, Triumph BSA's part number is 57 2166 or T2166. They should fit just about any vintage Triumph or BSA engine. Listing is for one pair. Second photo shows the difference in look between these plugs and the standard cast crapola.
