RFN SX E8
The RFN Warrior Pro SX‑E8 is designed for advanced young riders ready to step up toward 65cc‑equivalent performance. Suitable for riders around 140–160 cm tall, it combines exceptional torque, extended range and a reinforced lightweight chassis for confident trail riding and competitive development.
With a powerful electric motor delivering up to 13.5 kW peak output and a 2100Wh lithium battery, the SX‑E8 offers strong acceleration, a top speed of up to 85 km/h and a range of up to 60 km. Adjustable suspension, hydraulic disc brakes and stable long‑wheelbase geometry ensure controlled handling across demanding off‑road terrain.
Low maintenance, quiet operation and optional app‑based power tuning make the SX‑E8 an ideal progression bike for serious youth riders developing speed, control and confidence.
