Let customers speak for us
I installed this on a 2022 RC390 that I use for a track day bike. I could not be more pleased with the performance of this shock it is a huge upgrade over stock. within two laps I was on my previous year PB lap time with far less effort. Out of the box first impression was WOW! this is a well made very nice piece of kit, installation was a Breeze. For anyone on a budget like Myself trying to improve your bike and skill you cant go wrong with this for the price. My hat is off to YSS for producing a shock like this for guys like me.
We went for a long bike ride Friday and Saturday. The ride was very comfortable. The shock worked flawlessly. We are very pleased with the set up.
Extra ordinary customer service! These goals really care about their customers and they know their stuff.
Great product. I ran into issues during the installation, after 5 minutes on the phone with Mike I was back on my way. Mike filled in the blanks of the instructions and he was great to talk with and did not feel like I was inconveniencing him with my questions. He was even cool on the second call...these guys care about their customers.
The installation was easy and made my BMW R1200GS steering much less "twitchy".
Very pleased! EPM shipped promptly and kept me updated on my order status.
Fantastic. Such a huge improvement over the stock suspension set up. This bike has never ridden so well. Firmly planted, feels like it's locked onto the road. Soaks up everything from the smallest imperfections to the worst expansion joints. No more spine crushing blows! It will make you fall in love with your bike all over again.
I installed these with the -30mm Hyperpro rear spring. The front end doesn't dive hard anymore when I hit the brakes. And the suspension feels better overall; the bumps aren't near as bad. The lowering also helped me with getting flat footed. Extremely satisfied.
Always helpful and professional!
Thank you!
