KTM Macina Race SX: suspension setup & specs
The KTM Macina Race SX is an e-hardtail with 100 mm of fork travel. It is powered by Bosch PERFORMANCE SX BDU3144. This page lists the 1 current builds with fork and gives matching starting values for SAG and tyre pressure.

How it compares
At 100 mm, fork travel is 20 mm shorter than the median of the “e-hardtail” category (120 mm, 27 bikes). On travel, it slots in between the KTM Macina Aera and the KTM Macina Team in the KTM range.
The KTM Macina Race SX does well on weight: 17.3 kg for the 10 build is 7.1 kg below the median of comparable bikes (24.4 kg). Every build uses a RockShox fork. Drive comes from Bosch PERFORMANCE SX BDU3144, paired with 400 Wh of battery capacity. Worth knowing for heavier riders: the maximum system weight is 136 kg – after about 18 kg of bike, that leaves around 118 kg including kit.
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: turn the red RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- e-MTB: because of the extra weight, start with slightly more tyre pressure – the surcharge is already built into the table below.
- Hardtail: without rear suspension, rear tyre pressure largely decides comfort and traction – it is worth testing in 0.1 bar (1.5 psi) steps.
Target SAG for the KTM Macina Race SX
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion. Change the pressure step by step until you reach the value; if KTM gives its own target SAG, use that.
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
The values apply to 2.24″ wide tubeless tyres with a trail casing, including the e-MTB surcharge. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi). Stock tyres: Maxxis Rekon Race EXO/TR 57-622 / Maxxis Rekon Race EXO/TR 57-622.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.58 bar (23 psi) | 1.78 bar (26 psi) |
| 70 kg | 1.70 bar (25 psi) | 1.90 bar (28 psi) |
| 80 kg | 1.82 bar (26 psi) | 2.02 bar (29 psi) |
| 90 kg | 1.94 bar (28 psi) | 2.14 bar (31 psi) |
| 100 kg | 2.06 bar (30 psi) | 2.26 bar (33 psi) |
| 110 kg | 2.18 bar (32 psi) | 2.38 bar (35 psi) |
| 120 kg | 2.30 bar (33 psi) | 2.50 bar (36 psi) |
Air pressure in the fork
The sticker on the fork and the manufacturers’ setup charts give you a first pressure. Our calculator is more precise and suggests rebound too – always check the result via SAG.
