YT Decoy SN: suspension setup & specs
The YT Decoy SN is an e-MTB for trail and touring with 170 mm of fork travel. It is powered by FAZUA (60 Nm). Below you will find all 3 current builds with fork, plus SAG values in millimetres and a tyre pressure table.

How it compares
With 170 mm at the fork, the YT Decoy SN sits above average: across the 101 bikes in the “e-MTB for trail and touring” category in our database, the median is 150 mm. On travel, it slots in between the YT Decoy SN 29 and the YT Decoy in the YT range.
In total, 3 different forks are used, from the RockShox ZEB Select to the FOX 38 Float Factory. It is powered by FAZUA (60 Nm).
Setup notes for this spec
- Air fork (RockShox ZEB Select): 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.
- 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 SN
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
Basis: 2.60″ tyre width, tubeless, trail casing, including the e-MTB surcharge. If you run tubes, add about 0.2 bar (2.9 psi); with an insert, about 0.1 bar (1.5 psi) less is enough.
| 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.
