Fresh off Cooper Webb’s 2021 Monster Energy Supercross Championship, we are seeing the 2022 KTM motocross lineup. There are a dozen models to choose from this year, from the electric-powered SX E 5 to the flagship 450 SX-F. With 2020 so chaotic, updates are minimal. Every adult model gets new graphics, but there is more. So, let’s go through the changes.
2022 KTM 450 SX-F. The big dog gets new rocker arms this year for the SOHC powerplant. According to KTM, the new rocker arms are light and stiffer. According to KTM, this results in a throttle response improvement everywhere in the powerband.
2022 KTM 350 SX-F and 250 SX-F. KTM has put new bearings in for the DOHC motors’ balancer shaft. The new bearings will reduce friction and performance at high rpm.
2022 KTM 250 SX, 150 SX, and 125 SX. There are no functional changes to the KTM two-stroke motocrossers for full-sized riders.
2022 KTM 85 SX 19”/16”, 85 SX 17”/14”, 65 SX, 50 SX, 50 SX Mini. Like the adult models, the mini KTM motocross two-strokes for youngsters are unchanged. Graphics remain the same.
2022 KTM SX E 5. The electric-powered mini-motocrosser, which features highly adaptable ergonomics, will be the same in ’22 as last year.
The 2022 KTM motocross lineup makes its way to dealers this month. We don’t have prices yet.
