2021 Indian Challenger Dark Horse that I love and can't ride. Bike is currently in the shop for the 3rd time regarding a loud tone/vibration/noise coming from the motor. It isn't very loud but after riding for 20 min or longer it really kills the experience. The sound is so annoying it has given me headaches and ear aches. Unfortunately today I located other threads describing similar issues on other Indian models. I really hope they figure the problem out. I want it fixed or replaced.... Polaris/Indian please..... can't imagine spending close to 30k on a paper weight. I will keep everyone posted on what Indian does with my bike. Also if anybody has had similar issues please let me know how it was fixed.
