Mine has been diabolical, in the shop for 2 months out of the 7 I've owned my 2005. First off I had the front brake grabbing syndrome, turned out the bike needed a new cast wheel, two rotors and pads; that and a couple of weeks in the shop.
Electrical failure, charging system blew a fuse and destroyed a battery, original cause of this not proven or fixed to the best of my knowledge. Two days in shop, and a roadside recovery required.
Most recently I took the bike into the shop in the first week of January... it's still bloody well there. The symptoms was excessive oil consumption, about a liter every 1k miles. After a couple of weeks of analysis Triumph agreed to an engine rebuild, valve guides, new cylinder bushes, cylinders, rings etc. That was all done then the bike wouldn't idle or run smoothly, another couple of weeks farting around and the shop figured it was something to do with the fuel delivery mechanism or whatever they came up with. Triumph agreed with the shop and they are replacing the lot.
That is where I am right now, Tiger less and considering a lemon law attorney. I am just really glad I could afford to keep my 98 Thunderbird Sport. A brilliant bike that is not only fun to ride has only had one minor failure (ignition sensor relay) fail in 8 years and 35000 miles. The Tiger on the other hand has lived up to the expectations of a 1950's Tiger. Load of ***** really.
Believe it or not I still love the Tiger, it is a fantastic bike to ride when it is actually on the road. It took me safely down through Baja and back up mainland Mexico on a 4k jaunt without a hitch so at least it picked a relevantly convenient time to take a sicke or two. :hammer:
