2025 GASGAS EX Complete Suspension Setup Kit
Race-Ready Confidence for the Cross Country Rider – Full Fork & Shock Upgrade
The all-new 2025 GASGAS EX models are fast, light, and aggressive — and now, with Krooztune’s Complete Suspension Setup Kit, you can unlock their full potential. This performance-driven package combines our 25 Series Flow Adjuster Fork Kit with our Linkage Shock Piston System, giving you unmatched control, comfort, and adjustability across all types of off-road and cross-country terrain.
Whether you’re carving through singletrack, attacking fast grass tracks, or racing enduro-style events, this kit delivers the suspension feel you’ve been chasing.
What’s Included:
Front – WP XACT '25 Series' Flow Adjuster Fork Kit
• CNC base compression pistons with Krooztune-spec shim stacks
• 25 Series Flow Adjuster mid-valve post with external clicker assembly
• Medium setting pre-installed (optional soft/firm options included)
• 20 real clicks of compression tuning range — adjust on the fly
• Rebound setup guide tailored to your spring rate
• Setup sheet included for easy install
2 Stroke models we recommend the 12n Pressure Springs
4 Stroke models we recommend the 16n Pressure Springs Options
Rear – XACT Linkage Shock Setup Kit
• Billet-machined 4-port compression piston with genuine KYB piston band
• Rebound and compression valving matched to your spring rate
• Multiple setup profiles included: Soft / Medium / Firm
• Nitrogen bladder kit for improved small bump response and feel
• Shim options and setup documentation included for fine-tuning
Why It Works:
Front Fork Performance – 20 Clicks of Real Control
The 25 Series Flow Adjuster delivers trail-to-track flexibility with 20 full clicks of external compression adjustment — no tools required.
- 1–10 clicks out: Firm, race-ready MX-style support
- 10–20 clicks out: Plush, planted action for trail or technical terrain
- OEM adjusters still operate for micro-adjustments
- Quickly tune to conditions — rocks, sand, roots, or hardpack
Rear Shock Setup – Tuned for High-Speed Precision
Built to suit the latest 2025 WP XACT linkage shock on GASGAS EX models, our 4-port piston with custom valving enhances every part of the stroke. The nitrogen bladder conversion improves initial response and small bump feel — with rebound and compression settings that bring out the best in your spring and riding style.
- Progressive valving = comfort on chop, support on hits
- Rebound tuning based on your spring = max drive, less kick
- KYB piston band ensures fade-free performance over long motos
- Custom valving available — just contact us for special requests
