I have a 2002 GW Trike, conversion done by CSC. The bike had almost 40,000 miles on it and recently it developed a shake and vibration in the front end when I get the bike up to 60 mph. There is no shake or vibration at 50 or less. It is not highway specific and does it all the time. I took it to my local Honda shop and they told me that the front wheel was cupped and needed replaced. So I ordered a new tire and installed it and vibration at 60+ still there. (Not a bad deal even though it did not fix the problem, a new tire is always good) This is a phenom that just appeared this riding season. Last year there was no vibration. I am not sure if it is a trike issue or a GW issue. But I am looking for other things I can look into if the shop does not come up with any other items.
Any ideas?
