Complaints
Failed reverser mechanism recall. Dealer replaced the module and claimed reverese is still inoperable and I needed to pay to have it diagnosed. Even though the problem started with less than 1000 miles on the bike. Being unable to back the heavy bike up without assistance forces me to either try to push it when needed or have someone, or multiple people, try to push the bike manually creating risk of injury and property damage.
