How it compares
170 mm at the fork almost exactly matches the 170 mm median of the 56 bikes in the “e-enduro bike” category in our database. On travel, it slots in between the YT Decoy SN 29 and the YT Decoy in the YT range.
Every build uses a FOX fork. The fork line-up ranges from the FOX 38 Float Factory to the FOX Podium Factory. Drive comes from DJI Avinox (150 Nm), paired with 800 Wh of battery capacity.
Setup notes for this spec
- Fork (FOX 38 Float Factory): 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: on FOX suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- 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 YT Decoy X
SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and adjust the air pressure until it matches. Any figures from YT take priority.
170 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 29 mm |
| Trail | 20 % = 34 mm |
| Enduro / rough | 22 % = 37 mm |
| Bike park | 20 % = 34 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.60″ 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).
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.40 bar (20 psi) | 1.60 bar (23 psi) |
| 70 kg | 1.52 bar (22 psi) | 1.72 bar (25 psi) |
| 80 kg | 1.64 bar (24 psi) | 1.84 bar (27 psi) |
| 90 kg | 1.76 bar (26 psi) | 1.96 bar (28 psi) |
| 100 kg | 1.88 bar (27 psi) | 2.08 bar (30 psi) |
| 110 kg | 2.00 bar (29 psi) | 2.20 bar (32 psi) |
| 120 kg | 2.12 bar (31 psi) | 2.32 bar (34 psi) |
Air pressure in the fork
You will find a suitable starting pressure on the sticker on the fork stanchion or in the suspension manufacturers’ setup charts. Our calculator gives you a starting value including rebound for your weight and riding style. What matters afterwards is the measured SAG from the table above.
