Rewzter on 3/3/2020

What a great experience! I customized my first, and only, motorcycle. It’s started as a plain Jane I inherited. An 80’ BMW R100 that I bobbed, and had some custom rear frame work done. A vision I had perfectly executed by a local shop. With the change, the tops of both rear shocks were shifted forward quite a bit. After putting the bike together, had a shock problem being too long and not enough support. I tried those (crap) shocks you find all over the internet that says heavy duty - yeah right! I called this support line and was astonished at how J&P Cycle’s staff was able to find, and recommend, the perfect better-than-stock shocks. The rubber in the mount holes can be custom drilled/honed out for a custom fit. I highly recommend this company. The parts are always top-notch, and the staff needs some raises! Harley S.

Good shocks! Made a big difference in ride and handling on my 2014 ctx1300 deluxe

Great shocks!

DENNIS on 10/31/2019

easy install, had to use a vice to get bushing in, but no problem, stiff ride but was told to ride awhile to "break-in"

I got my Shocks yesterday and I'm very pleased. I had a different account with you for 15 years before I made this new account and have always been very satisfied with the ease of placing my orders and how quickly they arrive! Thank you very much!

Important Product Notes

Note: When shocks are different than stock length, clearance must be carefully checked for potentially dangerous interference.
