I want a fast motorcycle with nice looks and prefer 2 lights on the front like the Yamaha YZF R1. I also don‘t want too big rear tires.
The MSF course is designed for complete beginners and often has idiots teaching it. Braking is different with different bikes. Is it a cruiser, sport bike or something else that you are riding?
You might enjoy doing your own research. Check the statistics on the top motorcycle makers websites.
I suggest you learn how to drive a motorcycle before worrying too much on how it looks. All motorcycles look like the same when they go skipping across the pavement on their side. You mentioned an R1 bike, which is a 1000cc super sport. Then you talk about not too large of a rear tire. Well if you name off one of the most powerful race bikes on the market, of course you will get a large tire so it has a sliver of hope of transferring some of its power to the pavement. Also a fast motorcycle is a very relative term. A Kawasaki Ninja 250R is plenty fast if you are comparing it to a car. While it may be a weak motorcycle relative to the field of motorcycles, it will still beat just about any car in terms of acceleration and speed. (When I had one, it could get a 6'0 210lbs male up to 95mph.) Go take an MSF course so you can learn how to ride properly and live to tell about it. It will also get you some experience on other types of bikes so you can make a more educated decision later. Sport bikes are fun, but if you are entering the field looking for a fast bike you are looking at it all wrong. All motorcycles CAN be fast.
