Here are some of the most frequently asked questions:

Do I need an appointment?

We are an authorized Express Lane Service Center, which means that small projects such as oil changes, brakes, and other select services can be done in about an hour, with no appointment necessary. However, we recommend you call & set up an appointment for most other services.

Do you do pickup & delivery?

Yes! We have 2 enclosed trailers dedicated to bike pickup & delivery.

How long will it take for my bike to be done?

There are a lot of different factors that go into the length of a project (i.e. what service you are having done, what parts are needed, etc.), so talk with our Service Team about the specifics of your bike and what to expect when you call to make your appointment!

What is DYNO Tuning?

When a motorcycle rolls off the production line, it is calibrated to run with stock components and under certain weather conditions. Dyno custom tuning tweaks your bike to run to the ecxact performance components you have installed in your specific environment to bring you optimum performance results. 

Where can I find my service maintenance schedule?

Each vehicle has a different maintenance schedule. You can find your specific schedule listed in the back of your owner’s manual or service manual. You may also contact the Service Department to find out when your vehicle should be serviced.
