The rain has been falling and winter is here in Northern California. At JT&S Performance, we are already thinking about Spring and beautiful riding weather!

Winter is a perfect time to have routine maintenance or upgrades performed on your motorcycle. Whether you are interested in dyno tuning, new motor kits, or preparation for your race or track season. We would love to speak with you about your options! Be ready when the good weather returns!

Terry and Jim will be speaking at the next American Sportbike Night, March 1, 2010
Off-season maintenance and preparing your bike for riding season will be the timely topic.

JT&S Will also be featuring motorcycles at the Quail Motorcycle Gathering, May 5 in Carmel, California. We were proud to participate in the inaugural show last year, and look forward to participating again this year!
