The 2024 RR Race Editions continue to see developmental upgrades to ensure the brand is at the top of the performance category. Our Race Edition models are designed for the serious racer as well as the casual rider who are looking for a more aggressive bike. The KYB rear shock was jointly developed with Kayaba engineers & Beta’s R&D department, leading to a shock that is extremely effective in enhancing the Rideability of the bike under all conditions. 

New frame for 2024 has been developed for the Race Editions that improves the turning stability of the bike and reduces flex under heavy load but doesn't hamper the overall feel and rideability of the chassis.
