2020 model information continues to arrive, and the latest is KTM's youth motocross bikes. All of the smaller-sized motorcycles have new graphics to match the full-size SX models. The 85 SX has a reworked muffler with different wool packing, which according to KTM reduces the weight of it by 40 grams. The 65 SX has an updated ignition curve and now comes with an alternative needle for fine-tuning options for different tracks and conditions. The 50 SX features a new cast aluminum swingarm with different flex characteristics designed to improve stability and make chain adjustment easier. The lone change to the 50 SX Mini is the graphic update.
