Hello everyone! I have been lurking on this site for quite some time now as I have been looking for a trike for a while. I found a '99 motor trike with just over 17,000 miles on it. It appears to be in excellent condition and well taken care of. I took it for a ride and felt a little bit of vibration on acceleration. The owner has had it checked out and just told me that it has a bad universal joint and so they are going to replace the joint and the drive shaft to be sure everything is okay. Wouldn't it be pretty unusual for a u joint to go bad with that low mileage on a Trike? The bike was triked when new by the way. Could this be an indication of poor maintenance? The trike sounded good and looked immaculate. Should I turn and run? Any advice or suggestions would be greatly appreciated. Thank you in advance.
