The KTM 85SX forks 2025, equipped with WP XACT AER technology, are a key component of this lightweight and high-performance motocross bike designed specifically for young riders stepping into competitive racing. These ultra-lightweight 43mm upside-down (USD) forks use a split technology design combining an innovative capsulated air spring in the left fork leg with a reliable oil damping system in the right. This combination not only saves weight by nearly 1 kilogram compared to conventional coil forks but also allows riders to easily and precisely adjust suspension settings using a simple air pump, ensuring perfect suspension tuning for rider weight and track conditions.
WP’s Cone Valve damping system integrated into the forks offers almost limitless damping adjustability, marrying comfort with superb bottoming resistance. This system reduces friction through closed cartridge technology, maintaining constant damping for smooth and responsive suspension action lap after lap. The forks deliver excellent feedback and balance, significantly improving front-end control, cornering precision, and overall ride confidence, especially on rough terrain and jumps typical in motocross racing.
The KTM 85SX forks are paired with a fully adjustable WP XACT monoshock rear suspension designed to complement the front end in terms of damping and traction. Together, this suspension setup brings race-proven technology from KTM’s full-sized motocross range adapted perfectly for the 85cc youth segment.
Riders and reviewers praise the 85SX forks for their durability, lightweight construction, and ease of adjustability, making them a standout choice for youth riders seeking professional-level suspension performance. The ability to quickly modify air pressure settings without opening the fork and the balanced damping characteristics help young riders push their limits safely and confidently.
In summary, the KTM 85SX WP XACT forks provide young motocross racers with advanced suspension technology, combining weight savings, excellent damping, and adjustability tailored to the rigors of competitive youth racing. These forks enhance bike handling, comfort, and control, ensuring the KTM 85SX remains a top contender in the youth motocross category and an ideal platform for riders aspiring to compete at the highest levels. Whether training or racing, these forks deliver the precision and reliability expected from KTM’s Ready to Race philosophy.
