Product Overview
The Royal Enfield 148546/B Rear Spindle-Long is the primary structural axle that secures the rear wheel hub to the motorcycle’s swingarm. It is designed to maintain precise chain alignment and brake disc positioning, which are critical for both safety and performance.
Constructed from high-grade steel with a specialized anti-corrosion treatment, this genuine spindle is built to resist bending and wear even under the heavy loads of touring or pillion riding. Unlike shorter spindles meant for older UCE models, the “Long” version is the factory-correct length for the wider hubs and swingarms of modern Royal Enfield platforms.
