This kit is particularly suitable for enduro/cross bikes where reducing unsprung mass is desired. Compatible with many 520 drivetrains, it pairs well with KTM 250 SX (2018–2020) models, which are among the most commonly fitted. To maintain performance and longevity: regularly check the tension, clean and lubricate the chain after muddy rides, and replace worn components simultaneously to avoid premature wear of the kit.
