I used to have a 2004 Speed Triple. Selling it was a big mistake, I really miss the bike. No real quality issues, a few initial gremlins taken care of under warranty (frustrating at the time), but after that no problems. A blast to ride. I rode mine to Halifax and back last year, it's not the best touring bike is about the worst thing I can say about it. Power band is all low and especially mid-range punch, and tons of it. Top end is OK, redlined at about 9,500, wish it were a lot higher. The high mount carbon exhaust note was pure bliss, especially with the throttle whacked wide open, nothing like it really.
Brakes are strong, handling surprisingly good except some high speed wobble in long fast sweepers.
The 2004 was the previous generation. I have not ridden the new generation, which has upgraded engines, brakes, USD forks, wheels. Also the exhaust has been changed and underseat storage evaporated as a result. I'm too scared to ride a new Triple, because I'll probably end up buying the damned thing.
All new Triumphs come with standard 2 year unlimited mileage warranty. Cost wise, in terms of acquisition, maintenance and repairs, expect more than Japanese but less than Italian. There aren't a lot of Trumpet dealers in town, I highly recommend British Italian Motorcycle on Powell St. at the north end of Commercial Dr. in Vancouver.
I also currently have a 2005 Triumph Thruxton. That's another story. Too many f*n bikes, not enough garage space ...
