“2days after I bought this bike Kawasaki issued a stop sale and DNR due to faulty #5 crank bushing, and refused to buy the bike back but instead expected me to sit and pay payments and insurance on a bike that I can’t ride for possibly a year with no fix in mind so I had to trade it in and take a big loss on a brand new bike, kiss off Kawasaki that will be my last purchase from you.”

“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. …”
