Well I have just had the 24k service done ( a little late at 32K), replaced the chain (DID gold Xring) and sprokets and had the front brakes stripped, cleaned and new pads and she is like a new bike to ride. Needed 8 shims so it was no wonder she was a bit sluggish and starting to sound like a tractor!
It's amazing how different the bike is, you just don't notice the gradual deterioration when you ride every day.
Didn't have time to do the work myself so I had the work done at Tri Moto in Greenwich who were very helpful, worked very late to get the job done and were a lot cheaper than a main dealer, worth bearing in mind if you are looking for Triumph mechaincs in the London area.
This mornings ride to work was a real joy :D
