I have noticed that on many forums the Suzuki C90t is being discussed about front end wobble.Some say its the all ball bearing ,tires or the windshield and possibly balance. Most of the forums suggest that Suzuki put a cheaper bearing in half made up by plastic.Now this problem only occurs when you let go of the handle bars the most wobble on my bike takes place around 55 mph it does a death dance but i can still feel it slightly at 70-75 mph . I had many bikes that you could let go of the handle bars and no wobble and would keep the bike straight. Suzuki answer to this problem is don't let go of the handle bars. I notified the National Highway Traffic Safety Administration Toll-Free: 1-888-327-4236 and they said I was the only one who has made a complaint. I feel if its Suzuki's fault they should make good and fix the problem at no cost to the consumer. So if you have the same problem i suggest you call before someone gets seriously hurt.
