These shocks are designed for a wide range of 150cc to 750cc street bikes, scooters, mopeds and ATVs, and the single biggest reason to buy is the combination of a large CNC aluminum reservoir and nitrogen damping that noticeably smooths out bumps and reduces bottoming out for everyday riding and light off-road use.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003e320mm Eye to Eye:\u003c\/strong\u003e The measured eye to eye distance is the main fitment guide and helps ensure a direct bolt-on replacement for many small to mid displacement bikes and quads.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCNC Aluminum Reservoir:\u003c\/strong\u003e A large capacity CNC machined aluminum reservoir improves heat dissipation and keeps damping performance more consistent during longer rides.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eNitrogen Damping:\u003c\/strong\u003e Rear nitrogen shock technology filters out minor bumps and absorbs larger impacts for a more controlled, comfortable ride.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSteel and Aluminum Construction:\u003c\/strong\u003e Mixed materials offer durability where needed and keep weight reasonable while resisting deformation under load.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eAdjustable Spring Preload:\u003c\/strong\u003e The preload can be changed with a tool so riders can tune compression feel for load, acceleration or passenger weight.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUniversal Fit Range:\u003c\/strong\u003e Intended for 150cc to 750cc machines, scooters and ATVs, making it a flexible option for many modification projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product is geared toward hobbyists and mechanics who perform basic suspension upgrades on dirt bikes, dual sport machines, quads and small street bikes.
