TB: is our measurement of brake horse power the same unit as what the Europeans call HP?
The stock horsepower for a corked XR650R is around 42 horsepower from there you uncork it as the Americans call it and get around 48 to 50hp. Then you can do as my bike has been done and fit a HRC performance kit, head work with standard valves, carb mods etc etc which is good for around 63 hp. It is the torque that makes these bikes excel they can pull the bend out of a river 
More facts here
Europeans dont often use horsepower but normally quote kilowatts, or if they use horsepower it is metric against the Americans with XR’s would be imperial
