Yes! There is a belief that Harleys are unreliable, but this is largely unfounded. According to some studies, up to 70% of the Harley Davidsons ever made are still on the road. Critics have pointed to the often-decreasing sales figures coming from Harley Davidson. If a decades-old Harley is still in perfect working order, why buy a new one? The lack of regulation in customisation and mechanics, as well as tumultuous ownership in the seventies, meant that some Harleys were of lower quality and reliability. Overall, if correctly maintained, Harley Davidsons are very reliable when compared to other brands.
