davedavisdal

great riding shocks, just wish they had a baseline weight for setting so I didn't have to experiment with settings.

Shocks are great, easy to install and work much better than stock. Look and fitment is perfect.

After finding the right adjustment, my bike rides better than ever. I love these shocks
