I don't have a manual for my 04' XR 250, but when I took it by a motorcycle mechanic recently for a tire stem valve problem, he told me 10 to 15 lbs is good pressure for trail riding. 10 lbs is what he filled it to, and it seemed sufficient for our day of riding that followed.
Never go by the tire pressure on the tire. That is only the maximum amount. Always go by the tire placard on the inside driverside door frame.
50-55mph
230 lbs (dry)

The XR 250 will have more power, however, the SX80 will be quicker off of the line. It's not always just about brute horsepower, but rather useable power and how quick you can accelerate. In many circumstances the SX80 would be faster than the XR even though it doesn't have the most horsepower.
The Honda XR series motorcycles are a range of air-cooled single-cylinder four-stroke 5 XR 250R; 6 XR 250L; 7 XR 350R; 8 XR 400R; 9 XR 500 / XR 500R; 10 XR 600R. They are much smaller in size in comparison to the other bikes in the series and the xr400 had more suspension travel and a longer wheelbase.
it could cause some back pressure issues and blow up the bike...
