when I bought my bike, the dealer said I could buy the ESP at the time of purchase or at any time up to 75,000 miles. after 75,000 miles they need to do an inspection of the bike to make sure nothing is severely wrong with it. Guess it protects them against having to replace a motor or tranny for a $50 co-pay. I bought a 5 yr. ESP and the same holds true if I want to extend it once its expired. Problem is, now that I've put on after market slip ons, tuner, and de-catted head pipes, they can void the warranty any time they like, if they find out about the mods (so they say). Hope none of you tell this to Harley. Lets keep it our little secret :newsmile055:
