Bigger tires on Honda crf 250 motard?

I'm writing from Italy and i would like to ask you one thing about my Bike Honda crf 250 m. The original back tire is 130/70 r17 and it is not so nice to see, given that the bike could look better with a bigger tire. My question is if it is possible to change from 130/70 17 to 150/70 r 17 whitout changing the wheel. Or at least if 150/70 is too much, till which size i can use bigger tires without changing the wheels. I don't care about police, i mean if it is feasible. Thanks in advance for the answers, any suggestion is welcome.

What would be a good bike for me?

I'm 15, about 5 6-ish and 125lbs, so not very big. I'm wondering what kind of bike I should get, I want something with good speed and for it to be comfortable. I'm just starting out, so nothing insanely fast. My dad has a 99 ZX-11 which I like very much but it's far too much bike for me to start on. I can lift it off the kickstand fairly easily but I'm not really comfortable in doing so as it has a heavy weight of 600 ish lbs. What should I start on? I'm in to any types of bikes, Honda CB series, Ninja 250 s, Ducati Scramblers, etc. Recommend me something.

Walking a motorcycle home?

So I'm buying this bike on craigslist and it doesn't ride and I have no trailor or truck to get it home. Its about a mile walk from the sellers house, is it legal to walk it home and is there some secret method other than putting it in nuteral and pushing it. It's a 1986 Honda rebel 250 if that helps.

Added (1). I've only ridden rockets my entire riding carrer but I would like to start getting into cruisers. I know I like the look of thicker forks like what's stock on the honda phantom but I would like other ideas as well. I know I want fuel injectiong for sure, where I live about 50% of the time its under 40 degrees and I don't want to deal with a long warm up time. I also need it to be under $4500. I'm not quite ready to give up all the speed of my rockets but I need to be more comfortable on long rides.
