The three cylinder Triumph Daytona is an incredible motorcycle, but an absolutely horrible choice for a beginner. Its not that a beginner physically couldn't ride a Daytona, they could, but it's too fast.
Our friends at Regular Car Reveiws explain in their latest video that a bike like this requires patience that a young rider doesn't have. They'll inevitably get in a stoplight drag race with someone and that will be the last time they ride.
It's too good of a bike to be entrusted to idiots. It will taunt its rider to go faster and faster and it takes a mature rider to resist those urges and stay out of trouble.
