The primary difference between the Husqvarna and KTM ranges are that the KTM machines run KTM’s traditional PDS rear shock system with no linkage, while the Husky machines run a conventional linkage system.

The 250 and 300 EXC have balancer shafts that keep engine vibrations to a minimum
New slots in the outer
tube of the WP 48 mm inverted XPLOR forks feed more oil to the bushes which KTM claim reduces friction and heat build-up. Fork springs have been updated with a new polished surface to improve consistency while a new valve design is claimed to improve rebound damping performance. Compression damping is adjusted on the left and rebound on the right
All KTM enduro models are fitted with a polyethylene tank with a 1/4 turn bayonet style filler cap. Integrated fuel pump.
WP XPLOR shock absorber has been retuned for model year 2022 and has a new conical bushing between the pistons to improve bottoming reserves. KTM claim improved fade resistance and wear
