YSS Open Fork Cartridge Kit
Transform Your Front End: YSS CO308 Open Fork Cartridge Kit
Is your motorcycle's front end feeling vague, divey under hard braking, or harsh over road imperfections? The YSS CO308 Open Fork Cartridge Kit is a groundbreaking suspension upgrade engineered to completely replace your factory fork internals. Designed for discerning street, adventure, and track riders who demand absolute precision, this premium kit transforms standard front forks into a fully customizable, race-grade suspension system.
By upgrading to a true open-cartridge system, you move far beyond basic fork spring swaps or emulator valves. The CO308 kit provides independent, highly responsive damping control that keeps your front tire firmly planted. It ensures maximum traction, significantly improved cornering lines, and an ultra-stable ride whether you are carving through canyon twisties, commuting, or navigating off-road terrain.
Why Choose the YSS CO308 Cartridge Kit?
- Full 3-Way Adjustability: Gain ultimate command over your front-end behavior. The uniquely engineered fork caps grant you full access to compression damping, rebound damping, and spring preload adjustments.
- Precision Compression Control: Features a dedicated adjuster (typically offering up to 25 tactile positions) to control oil flow on the compression stroke. This allows you to stiffen or soften the initial hit and drastically reduce front-end dive under heavy braking.
- Tactile Rebound Tuning: Easily dial in the return speed of your forks via an audible clicker knob. This keeps the front wheel tracking smoothly over successive bumps without causing the chassis to feel loose, packed down, or bouncy.
- Threaded Spring Preload: Stop adapting to a one-size-fits-all factory setup. Use the top-cap threaded rings to compress the internal springs and set your exact rider sag based on your gear and riding weight.
- Eliminate Factory Limitations: Drastically improves front-tire grip, stabilizes the bike under heavy load changes, and eliminates the harsh, predictable bottoming out common with stock OEM setups.

Let customers speak for us
Just a little bit stiff but overall I would buy them again and I would recommend them to everyone who is wanting a much better ride.
1993 Honda Nighthawk 750 transformed by these shocks. Left them in the middle setting for rebound and it was perfect. The stock shocks had very little rebound damping so you get thrown off the seat right after a bump.
These are like a magic carpet and really settled the bike.
Rides good.Has plenty of adjustment. CRF300l much more stable.Handles better.
Product arrived packaged well and was exactly what was advertised on their website. Would do business again with EPM
I’ve purchased Hyperpro products before and this purchase did not disappoint Would purchase from EPM again as well.
