Product details :

Features

Manufacturer Ref: FXRS 90-43 99SV — RFX Pro Series Trials aluminum sprocket, pitch 520, 43 teeth. Designed for trial and cross riders looking for a lightweight, precise, and aesthetically crafted part.

CNC machined from high-quality 7075 aluminum, this RFX sprocket features an anodized silver finish and a laser-engraved logo. Its profile, developed using CAD, combines mass reduction with sufficient rigidity for transmission stresses. The drainage grooves limit mud accumulation between the teeth and chain, facilitating riding on wet and rough terrains.

Material: CNC machined 7075 aluminum
Number of teeth: 43
Chain pitch: 520
CAD optimized profile for weight reduction
Anti-mud drainage grooves
Brand-specific color code + standard silver version

Ideal part for trial/cross motorcycles (e.g., GAS GAS TXT PRO 125, 250, 280 depending on model/year). Standard replacement fitting: check compatibility with your sprocket and front gear before installation. A sprocket that combines a race look with terrain demands for your technical outings.
