How it compares
On travel, the KTM Ultra is right where the “cross-country hardtail” category usually is: 100 mm up front against a median of 100 mm from 46 bikes. On travel, it slots in between the KTM Penny Lane and the KTM Scarp MT in the KTM range.
At a minimum of 12.6 kg (1964 Pro 29 build), the KTM Ultra is heavier than its category median of 10.0 kg – 2.6 kg more. There are 1.0 kg between the lightest and the heaviest build. The fork line-up ranges from the RockShox Judy Slv TK to the Suntour XCM32 Air.
Setup notes for this spec
- Air fork (RockShox Judy Slv TK): the air valve is on top of the left leg under a cap. Change pressure in small steps (about 5 psi (0.34 bar)) and cycle the fork a few times afterwards so the air chambers can equalise.
- Rebound: on FOX and RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Hardtail: only the fork needs setting up. With no rear suspension, rear tyre pressure is the key adjustment for comfort and grip.
Target SAG for the KTM Ultra
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion. Adjust the air pressure until the value is right. If KTM specifies its own target SAG for your model, that takes priority.
100 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 17 mm |
| Trail | 20 % = 20 mm |
| Enduro / rough | 22 % = 22 mm |
| Bike park | 20 % = 20 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.24″ wide tyres, tubeless with a trail casing. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less. Stock tyres: Maxxis Rekon Race 57-622 / Maxxis Rekon Race 57-622; Maxxis Rekon Race Exo 57-622 / Maxxis Rekon Race Exo 57-622.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.53 bar (22 psi) | 1.73 bar (25 psi) |
| 70 kg | 1.65 bar (24 psi) | 1.85 bar (27 psi) |
| 80 kg | 1.77 bar (26 psi) | 1.97 bar (29 psi) |
| 90 kg | 1.89 bar (27 psi) | 2.09 bar (30 psi) |
| 100 kg | 2.01 bar (29 psi) | 2.21 bar (32 psi) |

| 120 kg | 2.25 bar (33 psi) | 2.45 bar (36 psi) |
Air pressure in the fork
You will find a guide value for air pressure on the fork sticker or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.
