Overview

The JT Sprockets JTF1539.14RB is a front countershaft sprocket designed for motorcycles. This rubber-cushioned sprocket features 14 teeth and is compatible with 520 chain sizes. It is constructed from heat-treated C45 steel and SCM415 chromoly steel alloy for durability and strength.

This sprocket incorporates a rubber cushion, a technology widely adopted by major Japanese motorcycle manufacturers since the early 1990s. This design element serves to dampen the impact of the chain on the sprocket teeth, reducing drivetrain noise and improving ride comfort. The heat-treated and bead-blasted construction further enhances its longevity and performance.

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.
