I currently ride an ´84 V65 Magna - have had it for years and love the bike. I´ve wanted an ST1100 since they came out (now a 1300!!). I´ve found a used one - ´91 with 87,000 kms (approx 55,000 miles). What kind of mileage can I expect to get out of this bike and what problems should I be looking for? Any comments appreciated.
