KTM Scarp: suspension setup & specs
The KTM Scarp is a cross-country full-suspension bike with 100–110 mm of fork travel and 100–110 mm at the rear. This page lists the 3 current builds with fork, shock and shock size and gives matching starting values for SAG and tyre pressure.

How it compares
With 100–110 mm of fork travel, the KTM Scarp is on the shorter side; the median of the 23 comparable bikes in the “cross-country full-suspension bike” category is 120 mm. On travel, it slots in between the KTM Penny Lane and the KTM Scarp MT in the KTM range. The frame is made of carbon.
At 10.3 kg (Master build), the weight is close to the category median of 10.8 kg. Depending on the build, fork and shock come from FOX and RockShox. The fork line-up ranges from the RockShox SID SL Ultimate to the FOX 32SC Float. Worth knowing for heavier riders: the maximum system weight is 110 kg – after about 11 kg of bike, that leaves around 99 kg including kit.
Setup notes for this spec
- Air fork (RockShox SID SL Ultimate): 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: turn the red FOX and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- Air shock (RockShox SID Luxe Ultimate|FlightAttendant): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
Target SAG for the KTM Scarp
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion and on the shock shaft. Adjust the air pressure until the value is right. If KTM specifies its own target SAG for your model, that takes priority.
110 mm fork, 50.0 mm shock stroke (Exonic)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 19 mm | 24 % = 12.0 mm on the shock shaft |
| Trail | 20 % = 22 mm | 28 % = 14.0 mm on the shock shaft |
| Enduro / rough | 22 % = 24 mm | 30 % = 15.0 mm on the shock shaft |
| Bike park | 20 % = 22 mm | 27 % = 13.5 mm on the shock shaft |
100 mm fork, 47.5 mm shock stroke (Master, Prime)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 17 mm | 24 % = 11.4 mm on the shock shaft |
| Trail | 20 % = 20 mm | 28 % = 13.3 mm on the shock shaft |
| Enduro / rough | 22 % = 22 mm | 30 % = 14.2 mm on the shock shaft |
| Bike park | 20 % = 20 mm | 27 % = 12.8 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.40″ 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: Continental Dubnital 60-622 / Continental Dubnital 60-622; Maxxis Rekon Race MaxxSpeed/EXO/TR 61-622 / Maxxis Aspen MaxxSpeed/EXO/TR 61-622.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.43 bar (21 psi) | 1.63 bar (24 psi) |
| 70 kg | 1.55 bar (22 psi) | 1.75 bar (25 psi) |
| 80 kg | 1.67 bar (24 psi) | 1.87 bar (27 psi) |
| 90 kg | 1.79 bar (26 psi) | 1.99 bar (29 psi) |
| 100 kg | 1.91 bar (28 psi) | 2.11 bar (31 psi) |
| 110 kg | 2.03 bar (29 psi) | 2.23 bar (32 psi) |
| 120 kg | 2.15 bar (31 psi) | 2.35 bar (34 psi) |
Air pressure in the fork and shock
You will find a guide value for air pressure on the fork sticker (or on the shock) or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.
