The bike rolls on lightweight, black anodized GIANT aluminium rims, fitted with MAXXIS MX-ST tyres for outstanding performance and stability on any terrain.

New "no-dirt" footrests offer improved grip and are less susceptible to hooking up

A digital ignition from Hidria provides improved processing power for a cleaner burn and smoother power delivery. All these features combine to make the 2025 KTM 65 SX an advanced and highly competitive 50cc mini-crosser.
