I think mine was in the mid 400's but had some other things done as well. I'm bracing myself for the 20,000 coming up next week which has a 3.5 hr. shop rate. Plugs (6), wires (6), oil, filers, gear oil, and check everything out, yea I'm gonna be in shock for sure.
I believe Triumph has a business benefit for each Rocket sold which translates into $$$$$. Not as bad as some but worse than some too.
