Suitable for all '70s British motorcycles with crossover pipe, Triumph part number 70-2271, but totally applicable to any Brit machine with 1 1/2" exhaust pipes.  ID of the clamp is 1 5/8".

Good luck and thanks for looking.

Buyers please note:  If you're buying multiple items (and lots of folks do), then when you're finished, please either 'Request Total from Seller' (me) or just wait for an invoice.  Ebay's shipping calculator is terrible and I ALWAYS combine shipping when possible for the cheapest cost to you.

Thanks for the help.
