Electric Dirt Bike Suspension Setup: Fastace, EXT Ferro & KKE Fork Tuning

How to set correct rider sag, spring rates, compression damping, and fork oil levels for aggressive trail riding.

Electric Dirt Bike Suspension Setup: Fastace, EXT Ferro & KKE Fork Tuning

Stock suspension on entry-level electric dirt bikes is often tuned for lighter 60kg–70kg riders. If you ride aggressive downhill tracks, jump tables, or weigh over 85kg with full gear, tuning your suspension is the best way to prevent bottoming out. All suspension upgrades listed below are available with genuine Australian stock from Electric Dirt Bike Australia.

Setting Rider Sag Aim for 25% to 30% of total travel in rider sag. If the bike compresses more than 35% under your weight with riding gear, you need a stiffer coil spring (e.g., 550 lbs/in or 650 lbs/in for the rear shock). [AMCA Australia's suspension tuning guide](https://www.amca.net.au/) provides baseline sag settings for Australian track conditions.

Upgraded Inverted Forks - Fastace ALX13RC: Budget-friendly, stiff 37mm stanchions with customised valving. - [EXT Ferro 36](https://www.electricdirtbikeaustralia.com.au/shop/ext-ferro-36-inverted-fork/): Handcrafted Italian air-sprung precision for maximum traction over braking bumps and roots — the highest-performing aftermarket fork for Sur-Ron and Talaria platforms in Australia. - Fox 40: High-end titanium spring for extreme downhill race use.
