The biggest reason to buy is improved ride quality: the rear nitrogen air design and large CNC reservoir help dampen bumps and reduce fade under sustained use, making them a clear choice for riders wanting a more controlled, comfortable ride without a full suspension rebuild.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e320mm Eye to Eye:\u003c\/strong\u003e Matches the critical mounting dimension for many 150cc to 750cc street bikes and quads so fit is straightforward when measured correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCNC Aluminum Reservoir:\u003c\/strong\u003e The large capacity tank is CNC machined from aluminum to aid heat dissipation and maintain consistent damping under heavy use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNitrogen Charged:\u003c\/strong\u003e The rear nitrogen shock filters out minor bumps and absorbs bigger impacts for a smoother, more controlled ride.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid Construction:\u003c\/strong\u003e Built from steel and aluminum alloy for durability and to withstand typical offroad and street conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Spring Preload:\u003c\/strong\u003e Tool adjustable preload lets riders fine tune compression feel and rebound to match load or riding style.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe shocks are best for owners of dirt bikes, scooters, mopeds, ATVs and small street bikes in the 150cc to 750cc range who can confirm a 320mm eye to eye mounting distance.
