I picked up an 85 500cc Honda Magna back in June. Rode it with a friend for about 2 months and now its been in the shop almost a month getting tires, chain and everything refreshed on it because it had been sitting a lot.
I'm only 5'7" and about 125lbs and the 500 fits me quite well. The V4 motor when tuned right is pretty fast, though its meant to be a cruiser. I'm license now which is a relief, the tests are harder then your day to day riding.
