R1 17.5 V7 ULTRA PREMIUM (ROAR APPROVED)

2015 ROAR On-Road Asphalt National and 2015 Reedy Winning Motor

ULTRA PREMUIM is basically an updated version of the previous motor.(updated version approved by Roar & has passed tech at Roar events)

Updated for v7 Ultra Premium

-Stator-

  • New stator has two front rings (makes your motor power more consistent throughout the run)
  • End wind (wire) is bonded in place to reduce vibration (improves initial acceleration & top end)
  • We also applied improved manufacturing techniques (proprietary) on both the same stator material & same wires (made in USA)
  • Compared to the previous motor based on beta user feedback, the motor improved acceleration,top end & power consistency throughout a race even at extreme temperatures (extreme temperatures not recommended,this will shorten the life of the stator).


Same parts as prior generation:

  • rotor
  • endbells
  • bearing
  • sensor
