Manufacturer reference: 4649 51 L
The ultra-light PBR aluminium sprocket 4649 in pitch 520 is designed for riders looking to lighten their final drive without sacrificing grip and durability on a daily basis or on the track. Machined to provide an appropriate diameter and tooth profile for pitch 520, it features 51 teeth to adjust the ratio and acceleration of your machine, whether on an aggressive trail, a lively roadster, or a motocross bike.
Easy to install as a replacement for the original sprocket, it allows for fine-tuning of engine behaviour (more top-end or more torque depending on the final ratio) and reduces rotating mass for a more responsive transmission. Examples of compatible motorcycles: BETA RR 480 4T X-PRO, VOGE 300 RALLY, BETA RR 480 4T RACE. Check the centring and number of bolts before installation.
