I bought my 06 S3 from Clinton Cycles. I used to roadrace with the GM, Bill Gash. If you go there tell him Fred Roush sent you. He's a great guy as are all the salesman and the parts and accessories guys. They were helpful in getting me fitted with a helmet and jacket. I had my 600 mile check-up done by their Service Department and they took the time to answer my questions and show me a few things about the S3.
I have also been to Fredericktowm Triumph. The Service Manager, Gerry Gentry, is a great guy. He's very knowledgeable and helpful. I had them install my Skyking Sliders and a TORES tune. The work was done once, done right, and the price was fair.
You can't go wrong with either place.
