FMF - Turbinecore 2.1 Spark Arrestor (Yamaha)

FMF – TurbineCore 2.1 Spark Arrestor (Yamaha)

The FMF TurbineCore 2.1 is the world’s best-selling spark arrestor — and for good reason. Built around FMF’s exclusive Turbine Dampening System, it delivers full, unrestricted two-stroke performance while staying 100% U.S. Forest Service–legal. Whether you’re hitting the track, racing enduros, or exploring deep backcountry trails, the TurbineCore 2.1 keeps your Yamaha running strong, sounding clean, and riding legal.

The straight-through design allows your engine to breathe freely, giving you a smooth, consistent power curve across the entire rpm range. The larger-diameter aluminum canister extends packing life and helps fine-tune performance, while the stainless steel end cap adds strength and durability. Best of all, there’s no clog-prone insert or performance loss — just pure FMF flow backed by decades of race development.

Why We Like It:
It’s the rare spark arrestor that doesn’t choke performance. You get that clean FMF sound, crisp throttle response, and smooth power delivery — all while staying compliant for trails and public land riding. It’s tough, race-tested, and totally maintenance-friendly.

Why It’ll Work for You:
This silencer keeps your bike legal without sacrificing power. The open-flow design means no buildup or clogging, so your engine stays responsive and strong ride after ride. It’s built to handle both aggressive racing and long trail days, and the larger canister helps the packing last longer before you ever need to touch it.
