The 05 has a smoother power delivery than previous years and in my opinion it is the best yet. :naughty:

The '03-'05 have the same motor with the exception of the '05 having very slightly lower compression. The '05 power is "smoothed out" with the help of a very restrictive exhaust pipe. Put a free flowing pipe on it and you won't notice a differance between the 3.

My personal opinion is that the 04-05 WRs have the best motors.
