I have an 05 with 18000 miles on it. Mine started with about 8k miles on it. Last year, under warranty the dealer put a new cam chain gear and chain, that worked for about six months. Rattle came back, so I called my dealer the other day and they are putting more upgraded parts in, new blades and installing a spacer in the tensioner. This is being done 9 months out of warranty and Triumph is picking up the tab.
