Vortex 253CZK-38 Black 38-Tooth CAT5 Aluminum Rear Sprocket

The Vortex 253CZK-38 is a 38-tooth CAT5 anodized black aluminum rear sprocket precision-crafted for motorcycle applications. Designed and manufactured in the USA, this sprocket is machined from a specially formulated aluminum alloy to deliver an exceptional strength-to-weight ratio that steel OEM sprockets simply cannot match.

Vortex's aluminum rear sprockets reduce rotating mass compared to stock steel units, which translates directly into improved throttle response and acceleration. The CAT5 black anodized finish provides a durable, corrosion-resistant surface that maintains its appearance through hard use. The patented Vortex tooth profile and saber-tooth groove design extend sprocket service life by distributing chain wear more evenly across each tooth.

Key Features:

• 38-tooth rear sprocket — ideal for fine-tuning gear ratios for acceleration or top-speed applications
• CAT5 black anodized finish for corrosion resistance and lasting good looks
• Lightweight aluminum construction reduces rotating mass for improved acceleration and handling
• 100% CNC machined in the USA from a specially formulated aluminum alloy per Vortex specifications
