definatly something wrong there. i have the 05 too and it's smooth as butter from 0 to the highest i've been which is 95. i would take it to the dealer and i'm sure they can find the problem which is probably something that was setup badly as has been suggested.
if you don't mind spending some $ on accessories, get yourself a set of Thunderbike pipes and some good fork springs and rear shocks. These bikes really love that stuff and you'll find the bike will be much better in all respects. Those 3 things are the only places where triumph dropped the ball on this bike. the pipes will really make it sound like it should, and the shocks and springs will make the bike ride and handle a lot better. Enjoy the speedy.....i love mine beyond words.
