GP Suspension 25mm cartridge kit that has helped national level racers get to the top step of the podium and changed the valving, spring rate, and travel to turn your dyna into a dream. GP knows that good suspension starts with a hydraulic system capable of absorbing every irregularity of the pavement your riding. GP has spent decades working with top level racers to perfect our system. GP has never outsourced any of their machine work or engineering. Everything in your front end is wholly American made in Ventura, CA, and they are proud of this. The end result? More traction, more comfort, and most importantly a ride that really puts a smile on your face. GP takes every rider's weight, and their style of riding into account when building their kit. They know that setup is key to good suspension, and we take pride into giving every rider a kit that is custom made for them. Whether you want a buttery smooth ride to cruise your bumpy home roads, or you want a ride on rails that can take the abuse of a track day. GP has you covered.
The kit is fully adjustable (preload, compression, and rebound). These adjustments can be found on your new fork cap. Some riders prefer to set it and leave it, while some riders like to tinker between setups.
Our 20mm cartridge kit, just like our 25mm kit is fully adjustable. There are 30 available clicks of compression, 30 clicks of rebound, and 12 turns of preload. Some people like to set their suspension and leave it, and some people like to tinker. Regardless, we guarantee we can find a setup for you.
