  The RFN Warrior Pro SX-E15 Plus is the largest and most capable bike in the RFN lineup.

  Built around full-size 21"/18" motocross wheels, a towering 920mm seat height and a race-focused chassis, the SX-E15 Plus is designed for riders who want the feel of a full motocross bike with the instant torque and low maintenance benefits of electric power.

  At its heart sits a 74V 40Ah Samsung lithium battery and a powerful motor capable of producing up to 21kW peak output and 650Nm of torque. The result is explosive acceleration, exceptional climbing ability and genuine motocross-level performance.

  My Take as a British MX Rider

  The SX-E15 Plus is the bike I'd point experienced riders towards if they want the closest thing RFN makes to a full-size motocross bike.

  The larger 21"/18" wheel setup completely changes the feel compared with the standard SX-E15. It rolls through rough terrain better, feels more stable at speed and suits taller riders far more naturally.

  If you're too big for youth-sized electric bikes and want a serious alternative to an 85cc or 125cc motocross bike, the SX-E15 Plus is where the RFN range really shines.
