PBR Standard Steel Sprocket 2134 - 520 (Manufacturer Ref: 2134 13 18NC)
Designed from PBR's competitive experience, this steel sprocket from the 2134 series is aimed at motocross riders seeking reliability for their 520 transmission. Its short 13-tooth design allows for precise adjustments of the gear ratio to adapt acceleration and engine response according to muddy or rough terrains.
The 18NCD5 composition provides good resistance to corrosion and abrasion while minimizing friction between the sprocket and chain. Ideal for riders looking for a robust sprocket for off-road use, it is suitable for 520 transmissions on motocross machines.
Common mounting examples: HONDA CRF 450 X (2024), HM CRE-F 450 X (2014), HONDA CRF 450 R (2024). Please check the pitch and compatibility of your shaft before installation.
