EK/PBR 428 SHDR Chain Kit - 13/49-124 by EK CHAIN, specially designed for motocross use. This kit combines an SHDR chain with a pitch of 428 and a standard steel sprocket with a ratio of 13/49 (124 links) to equip small displacement bikes and motocross models requiring a robust and easy-to-maintain final drive.
Designed to minimise friction while providing good resistance to tension and abrasion, this chain/sprocket combination is suitable for off-road use and amateur competition environments. The gold finish makes it easier to spot and maintain, while the steel sprocket prioritises durability on aggressive terrains.
Before installation, check the number of links and tension, properly lubricate the chain, and replace the clip attachment with a riveted attachment if necessary for intensive use. Compatible with models such as KTM 85 SX BIG WHEELS 19/16, HUSQVARNA TC 85 BIG WHEELS 19/16, and GAS GAS MC 85 19/16 (always consult the manufacturer's manual for confirmation of the final ratio).
