Focus JAM²: suspension setup & specs
The Focus JAM² is an e-MTB for trail and touring with 160 mm of fork travel and 150 mm at the rear. It is powered by Bosch Performance Line CX, 85 NM, 120 NM update via Flow App. This page lists the 4 current builds with fork, shock and shock size and gives matching starting values for SAG and tyre pressure.

How it compares
Up front the Focus JAM² runs 160 mm – 10 mm more than the 150 mm median we calculated from 101 bikes in the “e-MTB for trail and touring” category. The rear offers 150 mm, 10 mm less than the front. Within Focus’s e-mountain bikes, it sits between the Focus THRON² and the Focus SAM² on travel. Focus builds the frame from aluminium.
At a minimum of 24.4 kg (LTD build), the Focus JAM² is heavier than its category median of 23.4 kg – 1.0 kg more. Within the range, weight varies by 1.0 kg. Prices for the Focus JAM² start at €4,399 (7), below the category median of €5,500. For the LTD build, Focus asks €7,499. Depending on the build, fork and shock come from FOX and RockShox. In total, 4 different forks are used, from the RockShox Psylo Silver RC to the Fox 36 Factory. It is powered by Bosch Performance Line CX, 85 NM, 120 NM update via Flow App with a 600–800 Wh battery.
Setup notes for this spec
- Fork (RockShox Psylo Silver RC): 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.
- Shock (RockShox Deluxe Select): get on the bike in your normal riding position, step off carefully and read the O-ring. Always cycle the shock a few times after pumping.
- 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.
Target SAG for the Focus JAM²
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion and on the shock shaft. Change the pressure step by step until you reach the value; if Focus gives its own target SAG, use that.
160 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 27 mm |
| Trail | 20 % = 32 mm |
| Enduro / rough | 22 % = 35 mm |
| Bike park | 20 % = 32 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.60″ 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 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.
