The JT Sprockets crown reference JTR899.42 is a transmission part designed for replacement or modification of gear ratios. Made from C49 steel, it features a black finish and a tooth count of 42 teeth suitable for chain transmissions with a pitch of 525. Its standard profile easily integrates into setups that comply with this pitch and configuration.
Intended for the Cross and Roadster universes, this crown can be used on both off-road machines and high-performance trails and roadsters. It allows for adjustment of the gear ratio to modify engine response or replace a worn crown without altering chain/sprocket compatibility.
Examples of compatible motorcycles (common references): KTM 1390 SUPER ADVENTURE S EVO (2025), HUSQVARNA FE 501 (2018), HUSABERG FE 501 (2014). Always check the number of teeth and the chain pitch of your motorcycle before ordering.
