Spring is here and we are enjoying our beautiful Northern California riding weather!

We are excited to have a booth in the paddock area at this year's AMA West Coast Moto Jam. We are the only motorcycle shop at our home track of Infineon Raceway. We look forward to seeing new and old friends alike! If you are planning on attending the races, be sure to stop by and say hello!
Our booth will be featuring a demonstration big-bore kit from Revolution Performance, and showing a few bikes with the amazing carbon fiber bodywork by Al Lighton of American Sportbike. We will be giving out flyers which may be redeemed for a free base dyno run on our Land and Sea dyno.

We will also be updating live via our Twitter and Facebook feeds. Check back for photos!

On Monday and Tuesday, May 17 and 18th, Terry and Al will be performing a much-anticipated exhaust shootout, testing several mufflers for the Buell 1125 on the dyno. We will be updating regularly with photos, videos, Tweets and Facebook posts!

Here is an example video of Jim Higgins, in our dyno room!
