Not adapted — purpose-built. EXT took their decades of know-how from MX, WRC, and MTB suspension and engineered something from the ground up for the demands of e-moto: more torque at the wheel, heavier chassis loads, and riders who push harder because the motor never gets tired.\u003c\/p\u003e\n\u003cp\u003eThe result is an upside-down dual-crown fork with 36mm hard chromed steel stanchions (heat-treated 42CrMo4 with Superfinish surface treatment), 7000 series aluminum upper legs, 205mm of travel, and 44mm offset. The HS3 hybrid air spring — twin positive chambers working with a self-equalizing negative chamber — delivers the mid-stroke support and sensitivity EXT is known for, scaled up for the rigors of e-moto riding. The CGB (Continuously Guided Bushing) DU system gives you maximum torsional stiffness through the stroke with zero stiction.\u003c\/p\u003e\n\u003cp\u003eAvailable with your choice of Flat Crown or Drop Crown to match your bike's geometry. 20mm boost-compatible axle included.
