BETA RX 450

The RX 450 is a four-stroke built for hard laps. Keep on top of air filter hygiene and check valve clearances on a tight rota so the top end stays honest. Grease the linkage bearings and swingarm pivots often, especially after wet meetings and big landings. Every part listed here is fitment-checked for your bike. Filter by category, brand or price and get it shipped fast to your door.
