How does Arthur manage up long steep hills?
You can power up a hill with Arthur. If it's an extreme hill we recommend either Arthur 2 with custom performance that will give maximum hill climbability (this is for torque performance, not top-speed) or Arthur 3 for max performance.
If you want to ride on a car licence we can speed limit these models. to 50km/h. We do not recommend Arthur 1 for optimal hill climbability.
All NKD motorcycles have excellent hill climbability - even with 2-up!
