“I experienced coolant leakage after coming to a stop. The dealership spent a few days testing and making the repair. At approx.. 300 miles it did it again. Coolant is very slippery, if coolant gets on a motorcycles tires it would be all bad. From what I have been hearing, harley is having issues with coolant leaks on selected new bikes. This is a whole new design for harley davidson, used on 3 2014 harley davidson models. I really think the issue should be investigated.”
