Here is a copy of the non-covered items from the policy. Pay attention to number 14. Not that you couldn't get any coverage, but it does give them an out.
IMHO that policy with the # 14 provision isn't worth buying, if you go to a wider tire or different size wheel, if you change shocks or lower the bike, or change the exhaust it voids the warranty unless approved by MOCO... The only way around that is buying all HD parts... Then if they have the little checkered flag by there discription the parts is for for racing only which voids the warranty... It's a catch 22... I say forget the warranty if you plan to improve the bike... JMHO
