PBR Ultra-Light Aluminum Sprocket 270 - 520 — Manufacturer reference: 270 51 L
Designed for demanding riders, this PBR aluminum sprocket combines lightness and durability for both off-road use and sport roadsters. CNC machined, it features precise tooth spacing (51 teeth) suitable for pitch 520, providing a crisp transmission and good chain engagement. Its stainless finish and choice of quality aluminum ensure high resistance to corrosion and abrasion without adding weight to the transmission.
Ideal for replacing a 51-tooth sprocket on a 520 chain, it is aimed at motocross and roadster riders looking to optimize unsprung mass and transmission responsiveness. Examples of frequently fitted models: YAMAHA YZ 450 F, FANTIC XX 125, GAS GAS EC 300 F.
