JFG RACING Rear Axle Block Chain Adjuster for CRF250R/CRF450R Aluminum

Description

Product Overview

The JFG RACING rear axle block chain adjuster is engineered for serious off‑road riders who demand consistent chain tension and reliable axle positioning. Constructed from CNC‑machined 6061 aluminum, the adjuster offers a perfect balance of strength and light weight, adding only 2.88 ounces to your bike. Anodic oxidation creates a durable, fade‑resistant surface that maintains its bright color even after repeated exposure to mud, water, and UV light. Designed to fit a broad range of Honda CRF models—including CRF250R (2004‑2024), CRF450R (2002‑2024), CR125R (2000‑2007), and many others—the part replaces the factory axle block, delivering improved chain alignment and reduced wear on sprockets.

Usage

This chain adjuster is ideal for trail riding, motocross, and enduro events where precise chain tension can mean the difference between smooth power delivery and premature wear. Install it on any compatible Honda CRF model to keep the chain straight and the rear axle securely positioned, even under aggressive acceleration and hard braking. Riders who frequently adjust chain tension after long rides will appreciate the quick‑bolt design that eliminates the need for special tools.
