Hey guys. I am perpetually impressed by the YZ/WR450. I was reading in the Febuary issue of Dirt Bike magazine, I came across a YZ450F flat track bike with 67 horsepower. I know that the WR and YZ are very similiar, excluding the 4-speed vs. 5-speed. I was curious how the owner of that YZ got so much power out of his 450. Since Yamaha doesn't post torque and horsepower numbers, I am curious of how much power the produce stock (WR and YZ) and how much torque. Not many people have dynomometers in their garages, anyone heard a power rating from a manual, or technician?
