For example, high speed bumps can be compared to hitting a curb or a large bump in the road surface. Typically, this is a rider-comfort area of adjustment. Low speed is used for controlling chassis movements, grip, and tire wear. When the bike is in the corner and the chassis is loaded, any slight variation in the track surface would be considered low speed. If a shock can’t absorb the variation, the grip would be reduced. In a race environment, the ability to adjust both high and low speed is especially important, where every bit of grip available is critical. Is this Really What Pro Racers Use: Yes, all of Penske Racing Shocks Pro AMA and top-level racers run an 8987 series shock. It is simple to tune with predictable and repeatable results. **Note: not all makes or models are available. Check the application chart to see which shock models are available for your bike.
