Hi, I would like to make the big appearance A “unlimited”. I have been driving a 125-inch shadow for years. Which machine is recommended for driving hours/test…Chopper, Honda CB 500, BMW 850…everything is offered?! Are there any advantages or disadvantages with the individual machines? How much horsepower must a machine have at least for the big “A”? Does anyone have experience of how the examiners react when an old boy wants to learn to ride a motorcycle again. experience of any advantages/disadvantages.
