How it compares
With 80–100 mm of fork travel, the KTM Macina Aera is on the shorter side; the median of the 27 comparable bikes in the “e-hardtail” category is 120 mm. Of KTM’s e-mountain bikes, the KTM Macina Aera offers the least travel up front.
KTM quotes 27.4 kg for the 871 Lfc Di2 build; that is 3.0 kg more than the 24.4 kg median of 11 comparable bikes. Within the range, weight varies by 1.5 kg. The fork line-up ranges from the FOX 34E FLOAT to the Suntour MOBIE34-D Air. It is powered by Bosch PERFORMANCE CX BDU3840 with a 720–800 Wh battery. Worth knowing for heavier riders: the maximum system weight is 139 kg – after about 29 kg of bike, that leaves around 110 kg including kit. Depending on build or size, the wheels are 27.5 / 29.
Setup notes for this spec
- Fork (FOX 34E FLOAT): air goes in through the valve on top of the left leg. After every change, compress the fork firmly a few times before measuring SAG.
- 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.
- e-MTB: the extra weight mainly affects tyre pressure, which is why the table below already includes a surcharge. SAG is measured just as on a bike without a motor.
- 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 Aera
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.
80 mm fork (871 Lfc Di2, 873 Lfc, CX 720 Lfc, Pts 893 Lfc, Pts CX 720 Lfc)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 14 mm |
| Trail | 20 % = 16 mm |
| Enduro / rough | 22 % = 18 mm |
| Bike park | 20 % = 16 mm |
100 mm fork (872 Lfc, 872 Lfc Di2)
| 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 2.36″ wide tyres, tubeless with a trail casing, including the e-MTB surcharge. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less.

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.
