  1. Easy to use: User can easily operate with beginner ATV knowledge
  2. Safe to use: Proper design to prevent unsafe user operation
  3. Retain reverse lockout: Keep feature integrated
  4. Ergonomically Sound: User can operate safely
  5. Normal use durability: Normal ATV durability maintained
  6. Exposure to elements: Operates in all weather and off-road application normal to ATV use
  7. Race conditions: Can withstand racing operations, rough terrain, high speeds and long duration
  8. Lasts lifetime of vehicle: Components will last normal lifetime of ATV with little maintenance
  9. Safe for transmission: Shifts within proper RPM limits, computer overrides any improper user input
  10. Fast shifting: Shifts are made within one-tenth of a second
  11. Smooth Shifting: Shifts are comparable to normal operation
  12. Duty Cycle: Cycle of component operation will last at least one full fuel cycle
  13. Dynamic operation: Applicable and operational for both race and general usage
  14. Manufacturable: Easy to reproduce, No modification to model production process
  15. Lower cost: Reduce cost further (compared to P08310)
  16. Easy to install: Integration will not require professional installation
  17. Weight: All added components weigh less than 7lbs
