High Speed Shakes

Hello everyone,

Have broken in my C50T and took it out on the highway to see what it can do. I found that above 65 mph there is a huge increase in the vibration and the engine sounds like it is not going to hold together. I was interested in finding out if this was normal or if I have a problem with my bike. It would be very uncomfortable to travel at 75 on my bike for any long distance. I did buy the bike knowing that most of the time I would be travelling backroads and not really going faster than 65 most of the time. But I thought that I would occasionally be able to take a highway trip.

Thanks in advance.

Have you had the 1st service done?

If so did you do it or the dealer?

If you did it, did you check all the bolts, as well as a fluid change?

Part of 1st service is a bolt check, along with the steering head. They will seat in (loosen), along with the engine. I remember old British Twins (BSA Triumph, etc), all the nuts were lock nuts (aircraft type), they vibrated so bad, that if you didn't have them, you were tightening once a week.
Possibly loose bolts is the only problem. Try checking the torque specs.
