Leak Proof Fork Seals

06 & 97 Series

   

Leak Proof brand fork seals are guaranteed not to leak for as long as you own your bike, as long as they were properly installed. We also offer Pro-Moly seals, which are impregnated with molybdenum for even less sliding friction.

"I need to replace the fork seals in my 75 Trident. The last ones I put in only lasted 24 years so it’s time to do it again." - John from Pennsylvania

Virtually all O.E.M. type fork seals for Post-War Triumph BSA and Norton motorcycles are available from British Cycle Supply - please order using the manufacturer's part numbers.
