F43 MX Tune | LSC | 246 mm Travel
MX Tune is a motocross specific tune with balance, control, and bottoming resistance for the fastest speeds. It's firm suspension for maximum control and support for huge jumps, whoops and fast cornering. If you select the EBMX or MX spec, you’ll compromise a bit of trail plushness for improved bottoming resistance.
