The Bullet 500 makes 22 horsepower / 16 kW, factory fresh, at sea level.
We were riding two-up, with a tank bag (intercom, etc.), loaded pannier boxes (camera backpacks) plus a dry bag (clothes, misc) and two lens tubes (video camera & misc).
Highest elevation on this trip with this bike was 11,254 feet.
The Bullet does not make 22 horsepower / 16 kW at 11,254 feet.
Was it a rental?
I really want to fly in, rent an Enfield, ride around for a couple weeks, then fly home.
