Owner report 11510624 · 2023-03-07 (March 7, 2023)
I purchased this bike and have not been able to ride it, due to the severity of the safety and mechanical issues the dealer failed to disclose to me. Once I got the bike home and had it inspected by a reputable mechanic, he informed me the dealer couldn’t have inspected this bike without seeing the multitude of dangerous, and illegal modifications.

The deal…

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 …
