FWIW, I have two guys among the riding acquaintances who don't have a license (and haven't had for years and years) specifically because they don't want to take the DMV riding test on their big bikes and won't ride a little bike.
I too never had a Motorcycle class license, I only got one within this last year when our Governator Arnold wrecked his bike and they made a big deal out of it, saying anyone without the proper license will have their bikes towed.....couldnt imagine my CVO on a hook for some reason. I took the course, thinking, it would help me pass the written test easier, and I was told, I wouldn't have to take the riding test at DMV on my hog if I did, sounded logical enough to me. So I would ride up in my CVO, get off, and jump on those little midget racers, 175's at this school. lol, Im just a litle big for these puppys, Most of these bikes were beat up with broken signal lites, dented tanks etc. It was a full class, so the instructor felt since I was the most experienced rider, that I should take the bike with the wobbily front wheel, and bent handle bars. , lol, someone had smashed this one up good into a wall he said, and pointed out the marks to the class, one girl quit right then. So I got up-graded to the bike with only bent handle bars and no wobbily front wheel. I didnt fit too well, on this thing, my knees hit the handle bars, and was like riding a mini bike for me.
The first day, they did the walking drills etc. I got muscle cramps in my legs , lol, what a joke Im thinking, then the slow speed drills, my bent handle bars made it almost impossible to make a right turn in the s curve and figure 8,... but I did it. I barely passed the test. talk about losing confidense, (Of course, I did get deductions for trying to pull the front wheel off the ground and speeding which didnt help). Im not going to lie, the turning inside a box was hard on this pocket rocket, 1/3 of the this class failed. but I was in a class that had some no experienced riders in it. Long story short, I learned a few tips that help me riding, but after the test was done, and we all got our results, I jumped on my CVO, and did the test course at neck break speed, and aced it including the figure 8 etc. The instructor got pissed at me, yelling that the insurance wouldnt cover me blah blah blah, lol, he rides a honda, so I gave him a break.
Problem with a permit, you cant ride at night Julia, and you cant have a passenger, at least in cali its that way, so ernie zap cant ride with you

Id look on craigs list or ebay, buy a cheap 175, or 250 if I were you, practice, take the test at DMV, (unless you feel the school would help you again?), and after passing the test, sell the little bike. No matter what, in the test, focus on keeping your head up and looking where you want to go!!! Good Luck !!
