MTPA/MTPV
Controller
Independently developed and tuned by SURRON,
this controller employs a brand-new MTPA/MTPV control strategy
further optimizing the internal structure and circuit layout to
fully leverage the performance advantages of the HairPin
winding embedded permanent magnet motor.
Enhanced braking system
The high-strength motorcycle braking system features a 90% increase in caliper rigidity. The braking feel is light and linear, allowing for precise control with just one finger, ensuring safety for your off-road adventures.
Upgraded Drive System
The new carbon fiber core belt has excellent load capacity per unit width, excellent wear resistance and low thermal expansion coefficient, and the ultimate strength is increased by 60%. The surface of the pulley is coated with tungsten carbide, which is second only to diamond in wear resistance and hardness, greatly improves the strength and life of the pulley.
