I wouldn't be going too much on Triumph's numbers. The claimed increase in power with the 2010 Roadster either wasn't really there at the back wheels (extra weight) or was easily gained anyway. The removal of the restriction in the first 3 gears with the 2014 is also no big deal as most owners did that simply anyway. A more important factor is that the ECU in the new model is locked, which is perhaps why Triumph decided to derestrict it to prevent problems with owners funking things up by trying to do it themselves. If you think you might want to retune or enhance the bike's performance down the track, a 2014 may not be the best option. Go for the latest earlier model you can afford or if looking pre-roadster, go for a 2009, the best of the lot.
