I would head this advise. I worked in the service department of a BMW/Triumph dealership for 5 years. More times than I can count folks would get a killer new bike and straight away "make it better" with this and that, i.e. aftermarket exhaust, CPU modifications, etc... And more times than I can count a stock bike would wipe the floor with the modded bikes.
