I just got a set of RK Shocks with lowering blocks and all I can say is wow at the ride quality now. Its so amazing and no more cringing when seein a bump. I like the look of em on the 48 cuz it gives the back of the bike a fat look like the front tire does on the 48.
But they are super comfortable... you wouldn't think it was the same bike.
Agreed, better ride after the switch. Even the glide guys notice how well the newer stock models ride, take their rejects and add to your comfort for cheap.
