① Heavy-Duty E-Moto Suspension Performance — This 228mm inverted fork is designed specifically for high-performance electric dirt bikes, delivering stable handling, strong impact absorption, and consistent control on aggressive trails, jumps, and mixed terrain riding. Built around Arctic Leopard XE PRO S specifications, it provides a factory-level fit and geometry match for 19” and 21” wheel setups. ② Inverted Oil-Spring Damping System — A precision-engineered inverted suspension design with oil-spring damping delivers smooth compression, controlled rebound, and improved front-end stability under hard braking, high-speed riding, and repeated impacts. ③ Reinforced CNC + Forged Construction — Built with AL6061-T6 forged aluminum lower brackets and AL7075-T6 fork tubes, paired with a MAX CNC precision-machined triple clamp interface for increased rigidity, durability, and long-term off-road reliability. ④ Multi-Stage Adjustability — Full tuning control with high-speed compression, low-speed compression, rebound damping, and spring preload adjustments allows riders to fine-tune performance based on rider weight, terrain, and riding style. ⑤ Long-Travel Impact Absorption — 228mm of main piston travel provides enhanced shock absorption for larger impacts, drops, and technical terrain, while maintaining front-end stability and predictable handling. ⑥ Optimized Brake & Fit Compatibility — Designed with a 90mm caliper mount spacing and support for up to 220mm disc brakes (upgradeable), ensuring strong braking performance for high-power electric dirt bikes.
