4 Hours is probably a lot especially if you're new to bikes. I would find 2 or 3 spots along the way to stop and rest a bit. Be ready for one hell of a nap after the ride. Keep in mind that you spend more energy riding than driving a car. Constantly balancing, etc..
I drove my bike 34 miles to get it home. I had 0 prior relevant riding experience. I knew how a manual transmission works, but on a bike it still takes just a little practice to get the hang of. Hard to always remember what gear it's in when I'm used to just knowing in my car.
I had to do a little city driving which made me sort of nervous for the first few miles, but then the last 30 miles was back country road. Nice and easy! I could've made it 4 hours driving on the roads I was on, but I would've looked for a country store or two to stop at along the way.
Good luck!
