I think its case of finding a dealer/mechanic you can trust and hang onto them. Advertise them to your friends and keep them in business. Its just a pity they seem so few and far between.
Did you buy a new bike? Why the extended warranty when you get 2 years anyway....?
Ah! We get two years and unlimited mileage here in the states.
And your warranty should be honored at any dealer, though the next one may be much farther away.Scott
