2022 EXC-F Enduro Range - The four-strokes

2022 KTM EXC-F

Shortly after releasing all the details on the Husqvarna enduro models for 2022, this week KTM unveiled the orange versions of the bikes. We cover the two-strokes separately, here we focus on the four-stroke line-up of 250 EXC-F, 350 EXC-F, 450 EXC-F and 500 EXC-F.

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.

A one-piece aluminium swingarm manufactured using a gravity die-cast process with the shock mounted directly to the swingarm

The 2022 KTM Enduro range is expected to go on sale in Australian dealership this July, 2021.

The 450 and 500 EXC-F engines use a single overhead cam

350 and 250 EXC-F engine run a DOHC system

The 250 and 350 EXC-F engines use a double overhead cam cylinder head with DLC coated finger followers. The 350 uses 36.3 mm intake valves and 29.1 mm exhaust valves

2022 KTM EXC – Key Updates

Revised WP suspension settings for a firmer & more responsive feel
Improved oil circulation in the suspension for more consistent feedback
New MAXXIS MaxxEnduro tyres for unmatched grip in all terrains
Head-turning 2022 colors inspired by the Factory bikes
Bold design & retro colors for the revamped KTM EXC SIX DAYS line-up

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
