This is the FX upgrade to our previous best seller - the B3. The B4 features high-durability super-grip seat material to keep you in place, and heavy-duty DuraTech ballistic nylon reinforcements to prevent knee brace wear. The seat includes raised O.E.M. logos, just like the TC4. Track-tested by the FX race teams, the B4 is the pro rider's seat of choice.
Heavy-duty grip pattern top material. Improved ballistic material protects against knee brace damage.
Fitment: Black with Yamaha Logo
