Make no mistake, these machines are powerful and can catch the new and the experienced out.

Scottish police forces have real concerns about high performance bikes (big bikes) because many people don't have the skill or the confidence to ride these machines safely, and sadly the police and the emergency services have to deal with the aftermath of the death and serious injury involved.

Experience in Scotland suggests that other road users form a very small percentage in causing the death or serious injury of a biker. The riders usually lose control of their bike on bends or during an overtake.
