I have a 2006 Suzuki C90T. Today I was coming down a hill coasting and took my hands off the bars to relax the hands...yes, I know I shouldn't do this. Almost immediately, the front end began to wobble or shimmy. I tried this several times and discovered that slowing into about 45 mph is when the shimmy begins. If you let it go, it gets progressively worse. I only have about 2500 miles on the bike. Any ideas what could cause this? It is not noticeable with even the slightest grip on the bars.
