Tap the plus
Built for serious dirt bike days
Waterproof
Water-resistant electrical packaging is built for real trail splash and changing weather, but deep water, submersion, and pressure washing should still be avoided.
Ride Modes
Five ride modes plus RFN app tuning let you soften the bike for sketchy terrain or open it up when you want full performance.
Customer Support
Ride RFN backs the bike with stocked replacement parts, dealer support, and a warranty path for verified manufacturing defects.
Power
A 74V system and true 15kW peak output deliver the kind of instant electric pull that makes the SX-E15 Plus feel like a serious dirt bike.
Beefy Tires
Moto-sized wheels and aggressive off-road tires help the bike track through chop, roots, rocks, and real trail terrain instead of feeling like a toy.
Suspension
Fully adjustable race suspension lets riders tune rebound and damping for rider weight, terrain, and pace.
