Apologies that this is not a 'single cylinder item', however it is more-or-less the same frame...hope thats ok.
Triumph TR5T Trophy Trail Adventurer Genuine Original Seat. I bought years ago. I believe that it has been fitted to a bike but barely used. Condition-wise it is like 'slightly shop-soiled NOS', see pictures. The bolt holes could do with a tap running through them. If you know about these bikes you'll know that the pattern seats (about £170) just look wrong. £175 + P&P (< £10).
