We know that good suspension starts with a quality hydraulic system capable of absorbing every irregularity of the pavement your riding on. We've spent decades working with riders to perfect this system. Our system differs from our competitors on various points. It features velocity optimized 25mm compression and rebound pistons that are custom shimmed to your weight and riding preferences. The bagger is a big bike, so we found putting an additional base valve in the bottom of the cartridge helps maintain traction when the front is loaded suddenly such as a big bump or a situation where you need to suddenly get on the brakes. Where our competitors two piston systems tend to \"pack up\" as the oil struggles to quickly push itself through the single compression piston our 3 piston system gives you a seamless feel through the stroke.\u003c\/p\u003e\n\u003cp\u003eWe've never outsourced any of our machine work or engineering. Everything in your front end is wholly American made in Ventura, CA, and we are proud of this. The end result? More traction, more comfort, and most importantly a ride that really puts a smile on your face. We take every rideru2019s weight, and their style of riding into account when we build their kit. We 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. We have you covered.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eOur kit is fully adjustable (preload, compression, and rebound).
