While riding at normal speed, I heard a loud popping noise from the engine, followed by immediate power loss. The motorcycle shut off without warning and coolant began leaking heavily near the front wheel. There were no warning lights or symptoms beforehand. The bike had fewer than 3,000 miles on it and was well maintained. I had to tow the motorcycle to the dealership, where a teardown revealed catastrophic engine failure—including internal damage to the crankcase, pistons, and transmission holder. The issue was later confirmed to be related to a manufacturer-issued recall, which had never been disclosed to me prior to the failure. Despite the severity of the issue and the recall connection, the dealership was unable to complete the repair for over two months due to parts delays and poor communication. The vehicle was non-operational the entire time. This failure created a serious safety risk and resulted in over $1,900 in financial losses due to towing, alternate transportation, and financing costs.
