RFX Pro Series Armalite Composite Sprocket - Ref. FXRS 15-50 ALRD
Designed for motocross competition, this Armalite sprocket combines lightweight and robustness: inner ring machined from 7075-T6 aluminum and outer ring made of high carbon density HCS steel. The double ring concept reduces unsprung weight while preserving superior longevity of the teeth. The red anodized finish gives it a race look and resistance to external aggressions.
Main features:
- 50 teeth, 420 chain pitch
- CNC aluminum center 7075-T6
- Outer ring in HCS (high carbon density steel)
- Hex-Drive interface between inner and outer rings for optimized transmission and reduced stress on the rivets
- Lightweight CAD profile and increased stiffness to resist twisting
- New mud evacuation grooves to limit abrasion
- Color: anodized red
Installation and usage: designed to be mounted on a standard hub, follow the manufacturer's recommendations for tightening and the use of Loctite. Ideal for off-road and racing, it is particularly suitable for Honda CRF 150 R (2020, 2022, 2026) and other motocross models with a 420 pitch.
