A Look of Its Own
The HARDENDURO also gets a distinctive appearance that separates it from the rest of KTM’s Enduro range.

For 2027 there are updated HARDENDURO specific graphics alongside an orange frame, orange Factory frame protectors and several other orange details throughout the bike.
A black ribbed Diamante Factory seat completes the look, while the grey soft ODI grips and HARDENDURO bar pad add a few more model specific touches.
Made for Tough Terrain
The HARDENDURO specification is about more than appearance.
Protection comes from the skid plate, brake disc guards, Factory frame protectors and clutch slave cylinder protection. There are also front and rear pull straps, a radiator fan and wrap around handguards included as standard.
The WP XACT Closed Cartridge front forks feature base valve preload adjusters, while the Factory wheel set combines EXCEL rims with orange hubs and Metzeler 6Days Extreme tyres.
