Über dieses Produkt
Built for electric dirt bikes that demand more than what a stock fork can deliver. The FASTACE front fork uses a twin-tube cartridge with externally adjustable compression and rebound damping, paired with a coil spring sized to your weight at the order stage.
Internally, every fork is dyno-tested and shimmed before it leaves our shop. The result is a fork that feels supple over chatter, holds up under repeated impacts on rocky descents, and never packs down on the kind of long, fast trails our test riders run weekly.
Direct-fit on the bikes listed below — no adapter brackets, no proprietary hardware. Most installs take 40–60 minutes with standard moto shop tools.

Einbau & Setup
Einbau in 40–60 Minuten mit Standard-Werkstatt-Werkzeug. Vollständige Anleitung liegt bei.
Loosen and remove the front wheel and brake caliper.
Slacken the upper and lower triple-clamp pinch bolts; slide the original fork out.
Slide the FASTACE fork up through the lower clamp until the top of the stanchion is flush with the upper clamp; torque pinch bolts in the order specified by your bike manufacturer.
Reinstall the brake caliper and front wheel.
Set static sag to 25–30 mm with rider in full gear; adjust preload via the air spring or external collar.
Set rebound to 12 clicks from fully closed; adjust low-speed compression to 10 clicks from closed as a starting point.
Wartung
- Check static sag every 10 ride hours; readjust as fork seals bed in.
- Replace fork oil every 80–100 hours of trail use, or every 25 hours of race use.
- Inspect dust seals and stanchions for stone-strikes monthly; replace seals if wiper gives way.
- Re-grease lower bushings during every oil change; use FASTACE-spec 5wt fork oil.
Häufige Fragen
Q01Will this fork fit my bike?
This fork is direct-fit on the bikes listed in the Fitment section. No adapter brackets, no clamp shims. If your platform isn't listed, contact our engineering team — we may have a variant in development.
Q02Do I need to specify my weight when ordering?
Yes. We pre-install a spring sized to your weight + riding gear, and pre-tune compression / rebound damping to a sensible starting baseline. You'll be prompted at checkout.
Q03Is this race-legal?
Yes — our forks are used in EMX, Italian Enduro Cup and several Asian e-moto national series. There are no homologation requirements that disqualify them in the major series.
Q04Can I run a stiffer or softer spring later?
Yes, replacement springs are available in 0.5 N/mm increments. Use the chart above or email support@fastace.bike with your new weight for a recommendation.
Q05What's the warranty?
24 months from purchase against manufacturing defects. Crash damage, corrosion from improper storage and modifications by unauthorised parties are not covered.
