We Are Your Mechanics!


Here at Gustin Motorsports we pride ourselves in the highest quality work for the best possible price. Our value will prove itself most out in the desert or on the track and also on the roads when you depend on your motorcycle/UTV/quad to perform the most. 


We come from a long history of motorcycles & racing vehicles. Our mechanics and owner have ridden & worked on motorcycles their entire lives. We were the service manager and head mechanic at Champion Motorcycles in Costa Mesa for many years. After the late Champion Motorcycles sold to Del Amo we decided to begin our own shop for all the local Costa Mesa/Newport Beach/Orange County customers. We wanted to provide better service and a lower return rate. After almost two years of business we've achieved our goal and continue to service all of our customers bikes/quads/UTV's and jetski's with the best quality possible.

About Us


It all started at a young age when Mike Gustin took Graham and his brothers out to the desert for family trips. After riding all weekend the bikes needed service and of course Mike did his own. Graham followed suit and in no time he was working on his own bikes very early on.

After working on bikes at home in Costa Mesa for himself and his family over the years, Graham Gustin ​started to work on friends bikes and eventually made his way to being a parts manager at Champion Motorcycles and soon after the service manager until it changed ownership. 


Shortly thereafter he and the head mechanic left to begin a new chapter with the start of Gustin Motorsports. So now it's been about two years of hard work and here we are with lots of satisfied costumers and bikes coming in and going out every day. If you've had issues with other shops come give us a try. We promise you won't be dissapointed. Quality work by people who ride almost daily. We go by our motto; DONE RIGHT THE FIRST TIME.
