2025 KTM 65 SX – IGNITING SAN DIEGO'S NEXT GENERATION OF CHAMPIONS

The 2025 KTM 65 SX is the ultimate launchpad for young riders looking to step into the world of competitive motocross in San Diego and beyond. Designed to bridge the gap between play riding and full-blown race action, this mini-sized machine is anything but small in its ambitions. Engineered with the same READY TO RACE DNA that fuels KTM’s pro-level bikes, the 65 SX sets the benchmark in youth motocross performance.

Its lightweight, high-performance 2-stroke engine delivers responsive power that’s perfectly tuned for up-and-coming racers. Matched with a 6-speed transmission and class-leading cooling system, it allows riders to push harder and stay consistent throughout motos. The WP XACT suspension system—featuring fully adjustable components front and rear—ensures the 65 SX handles with maturity and precision, no matter the terrain or track conditions.

Beyond the power and suspension, it’s the little things that add up: a rigid chromoly steel frame, race-optimized ergonomics, and a high-quality Formula hydraulic braking system. The 2025 KTM 65 SX is purpose-built for kids who aren't just playing around—they're training to win. For families in Southern California looking to raise the next motocross prodigy, this bike offers the ultimate balance of performance, durability, and development potential.
