Here is the thing. ive a esa bike, and now im about to order hyperpro shocks without esa. Do i need a preload adjuster with that? a search here on the forum got me to a thread saying you can swap your oem bmw preloader to the hyperpro shock, but i dont have a proloader on my esa shocks (i think) Does anyone know what the lenght adjuster is for and if i need it? that is also an option. thank you.
