Catalyst Reaction Suspension Tuning 2420 Sand Creek Road, Brentwood, CA 94513

"New Edit 3/8/2024: Again Catalyst Reaction went above and beyond. They moved from San Carlos to the Antioch-Brentwood area and I couldn't be happier. Took my Aprilia RSV4 in for new tires, new chain, new sprockets and fluids change. Jim did an amazing job and is just an all around friendly person. Nickie is great with communication and also very friendly. They were very flexible about Motorcycle drop off and pickup times. I feel the cost of labor was very reasonable and would recommend them to any friend that rides. I am so glad to have a trusted mechanic local. Keep up the great work you two and thank you! - Erik Bally Original Post: Great experience getting my suspension adjusted. In and out in 15 minutes (had an appointment). Motorcycle safely lowered and handles better as well. I would recommend this place for sure! I came from Antioch based on the recommendation from California Speed Sports! Will definitely go back for other services."

"I had a 2009 ttr230 serviced due to jet and carb issues. She ran amazing afterwards! Thanks for the quick turnaround so I could ride the following weekend!"

"Starting issues with my 1100 vstar. Made (still has ) a grinding sound. Got starter gear kit and added oil & filter change. Took a ride up to Napa my oil fill cap shot off on the highway by Berkeley. Drenched in oil (includes bike) I pulled over. Bikes rear tire slipped twice trying to get safely to the side.Walked to gas station to clean up and buy oil.Found an old rubber glove and with paper towels I made a cap after filling her with the only oil the gas station had. Nothing is running right on my vstar now. Smh! Can't believe he can't get an oil change right.i did call him and he did call me back but it's not like I'm gonna have him work on it again."

"Jim, Nickie, and the rest of the staff at Catalyst Reaction are absolutely the best in the business! Not only are they experts at everything for the street and track, but they always take the time to make you feel valued as a customer and go the extra mile to help with whatever you need. If you're in the Bay Area and need anything for your motorcycle, you'd be remiss not to stop by and let these folks take care of you. They are simply the best shop you're gonna find, period."

"Although I didn't go to the actual store, I had them set up my suspension at an event in Sacramento today. The suspension guy was awesome and very knowledgeable. He explained things and advised beyond just the suspension. $40 well spent. Thank you!"
