Just saw a show on Speed where a guy said "Monkey Butt" was caused by riding long distances at higher RPM. (He was selling his 6 speed tranny conversion for a Harley BTW.) If you ask me you can get Monkey Butt sitting on your ass drinking beer! I don't think it has anything to do with RPM. It is in the gear your wearing and how well it wicks moisture away. How much ventallation your seat and gear provide.
