Overview

The RFX Armalite Aluminum/Steel Hybrid Sprocket is a 50-tooth rear sprocket designed for Yamaha motorcycles. It features a hybrid construction with a CNC 7075 Aerospace aluminum inner ring for strength and wear resistance, and an HCS outer ring for enhanced durability. This sprocket is color anodized for a factory bike look.

Designed with a CAD profile to reduce weight without sacrificing strength, it includes newly designed mud clearing grooves to minimize wear and debris buildup. The rigid construction increases torsional strength for reliable power transfer. This sprocket is compatible with Yamaha models from the 2020s and is engineered for riders seeking durable, high-performance drivetrain components.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
