Retired with a product engineering background and 3 back surgeries I'm sharing my suspension evolution with 5 trikes.
2011 Triglide stock air suspension and rear Dunlop at 26# (very bad ride always for back problems)
2016 Triglide with Legends air shocks, compressor, air gauge, Dunlop tires 26#( slightly better ride due to finding sweet spot pressure easier) After 3rd back surgery in 2016 Legends not good enough and I was ready do give up trike riding until.............I discovered Trike Talk and DK customs. With other trike owners help and DK Customs my story continues.
2017 Trike with Pro-Action coil over shocks, HD Hammock seat, Goodyear comfortread tires 20# pressure. WOW what an improvement mostly with shocks! We can ride again and had a record setting 2017 with 22,008 miles!
2020 Triglide and had to try HD's adjustable coil over shocks to see what I could get without adding anything. The ride was much improved from Harley's air shocks but still significantly less that Pro-Action shocks so added all the goodies I had on our 2017 Triglide.
Went to 2 wheels (used Ultra Limited) when Trike down all summer (mouse ate wiring harness in fairing $3000 damage and parts backlog until November. Sold 2020 Trike and stayed with 2 wheels (learned AGAIN it was too much for two people) 12-26-22 traded 2 wheels for...
2015 Trike (currently) and tried DK Customs Next-Gen shocks. I found no need to get rid of stock Dunlops and no need for a HD Hammock seat. Next-Gen shocks with 22# air pressure and nothing else is giving me the best ride yet for our 2015 Triglide!
Thank You forum folks for the advice and DK Customs many hours of R&D to offer great shock products!
