I went riding today and my stock Harley shocks were at ZERO. I just pumped them up the other day. I'm ready for my 40k service so I decided to spring for the Stage II suspension upgrade kit from DK Customs with the 14" NexGen rear shocks with lift. I average about 600 miles a week just going to work and back and then another couple of hundred more on the weekends after spring and usually average 12k-15k a year for all 12 months. I hope the ride will be much better than the last 20k since I bought the trike.
