A week later I had taken my Ninja to the shop again to get an aftermarket header put on. Great service from JJ and the team. I’m glad I found shop for literally all my motorcycle needs.
Will be going there again on June 22nd to get a tune done by Ryan.
Great staff, great customer service and overall, a great shop!
The bike literally feels brand new. Completely different riding experience now — way more stable, smoother, and the corners feel amazing.
Before, I felt every little bump in the road, and every lane divider made the bike wobble around like jelly. I was even getting some wobble in the bars because of it. Now I barely feel bumps or road markings at all — it honestly feels like I’m riding on a smooth road. The handlebars feel planted and solid in turns instead of shaky.
I honestly had no idea a suspension setup could change the bike this much. I’m SO happy with it ❤️
Thank you 🙏
I follow this shop on social media and was in the state with my newest bike.
I stopped in for a suspension setup.
The next day I went back to do some readjustments but we both knew I needed front fork springs in order to get the bike right for my weight.
They were happy to help me get it done same day.
JJ got to work on it smooth and fast.
I was able to hangout and wait for it.
Then made the long ride back to AZ.
Very knowledgeable friendly and happy to answer any questions. They also offer warranty.
Great prices!
If you have yet to have your suspension setup what are you waiting for.
Reach out to Suspension Matters in Azusa CA
They came nothing short of that expectation
They were so professional and very informative .
My forks were done quickly and I’m hopefully back on the road soon .
Would recommend this place to anyone that’s asks
Thank you for the help
Met Ryan and JJ, nice folks. 30 minutes in and out, took the bike for a quick spin around corners near my home.. oh my… it’s like on rails on corners!! It no longer fights me like before..
Thank you so much, JJ and Ryan, you guys are amazing!!
The shop has a great vibe. Bikes everywhere, racing memorabilia on the walls, and JJ is the kind of craftsman you just don’t see anymore. Word is his son is pretty damn fast too. I’m stoked he’s local to Duarte, because I’ll be bringing my bike back here. JJ does it all, and he’s a suspension expert across every motorcycle style. If you ride, you know how important dialed suspension is … it’s the difference between feeling confident enough to send it or not.
You’ll find him in the alley behind the gas station on Todd and Foothill, right across from Costco. Look for the airplane hangar-style garage. Tell him Bryan Dorsey sent you. 💯🎤🏁
I got quotes from Bert’s, m1, and several other highly recommended shops for my fork seal replacement—called Suspension matters and they quoted me literally half the price for the same work. IG we_move_different (real person—real review). This is what happens when you don’t try to screw you customers! they spread the word! I suggest this place to any and all riders! 🫡
