How hard would it be to ride a motorcycle when I've never rode a bicycle in my life?

So my friend recently offered me to ride his Honda CBR250RR the next time I see him. But, the thing is I've never rode on anything with two wheels before. Not a scooter or a bicycle. The only experience I've had with anything similar is on my ATV. Would it be harder to ride a motorcycle? I've heard that going fast is much more stable than going slow. Any other tips from you riders out there? If so, thank you very much!

Added (1). The bike is a project bike so it's not like it's too bad if I drop it. My friend himself has even said that it's fine if I drop it. I'm helping him fix it anyways. We're also going to be on a private road so traffic obviously isn't an issue. I'm a beginner that's simply practicing, not riding on the road or anything dumb such as that.

It will be hard at first may seem overwhelming but just start slow don't do anything you don't feel comfortable doing. Always nice to have guide to help you your first few days and that's a great bike to start on remember all the gear all the time look where you want to go hug the tank with your knees and become very comfortable with counter steering (push left go left)

You will crash with 10 seconds. Learn to ride a bicycle first and stay off your friends bike

It will be faster, safer, and cheaper to learn first on a LESS than 20 pound bicycle than on a MORE than 200 pound motorcycle!

Going fast in a straight line is *easy* -- turning it the tricky part. At walking speed you steer left to go left. At higher speeds you try to steer right to go left -- counter steer. I figured out when I was 2 years of age on a girl's pedal bicycle (the seat was about head high.) You need to ride a pedal bicycle until you no longer try muscling it around and riding becomes instinct -- then you can try riding a motorcycle.

My tip?

Don't do it.
