2025 KTM 350 SX-F – THE SWEET SPOT FOR SAN DIEGO RACERS

The 2025 KTM 350 SX-F continues to dominate the middleweight motocross category by striking a perfect balance between the raw power of a 450 and the flickable agility of a 250. For riders across San Diego looking to sharpen their lap times without sacrificing control, the 350 SX-F is the ultimate secret weapon.

This machine is engineered for versatility — light enough to whip through tight ruts at Barona Oaks, yet potent enough to charge the big lines at Glen Helen. A refined chassis, premium suspension, and cutting-edge electronics come together to deliver a ride that feels planted, confident, and aggressively fast across any terrain Southern California has to offer.

Whether you’re dialing in your lines for weekend motos or battling for position at the front of the pack, the 2025 KTM 350 SX-F gives you the edge. It’s not just a compromise between classes — it’s the evolution of competitive motocross for riders who want the best of both worlds.
