Absolutely TOP NOTCH, all around! Great company, great people, great service. They always get my bikes running their best and today was no exception!! Thanks again Catalyst Reaction, see you soon! – Brett B. / Walnut Creek, CA

All I can say is WOW. If your bike’s suspension feels less-than-perfect, head to Catalyst, pronto. – C. D. / Menlo Park, CA

Jim is a pro and was in and out in 30 with a very short wait. Get your shocks adjusted and get it done here. – Yuichiro S. / Piedmont, CA

I brought my bike in for a few different issues at various times and Jim explained to me exactly what he thought should be done in order of priority. He did oil change. He did carb clean. He installed new clutch. He installed new regulator and even attached it to a different location on the frame to prevent overheating that the factory installation location was notoriously known for. Jim and his partner Nickie really, really are cool and kind people. – Andrew K. / San Carlos, CA

These people are very friendly! They never give you the cold shoulder and it’s always nice talking to them! Definitely a recommended place to go if you need your suspension professionally done or any bike service! Thanks Jim and Nikki! – Daniel Y. / Burlingame, CA

Prior to coming to Catalyst Reaction, I had already have suspension tuning done at evolution motorcycle in santa clara but was unsatisfied with how my bike handled afterwards. So i went for another try with Catalyst Reaction a few weeks later and after Jim worked on my bike, I immediately felt more confidence just riding in the parking lot and onto freeway ramps. But the real test was when i took it up to mt hamilton and mines road where all the bumpy canyon roads are and sure enough the bike handled like it’s supposed to, predictable and confidence inspiring with improved mid corner stability. – Kyle L. / San Jose, CA

I continue to take my motorcycles into CRS Tuning. Communication and service is exemplary. Took in my FJR1300 to get serviced along with rear trunk installation. I know I am being treated fairly and most importantly I trust them. – Todd T. / Menlo Park, CA
