I bought my first motorcycle exactly a year ago, it is an 1991 honda shadow vlx 600cc. I put about 3000 miles on it last year and don't have any problems on the highway or anything. I want to get rid of my cruiser and get into something like an older gsxr 600 or maybe a cbr 600 f4i. Everything I read has been saying that 600cc sport bikes are to much for beginners. I've only driven a few of them so I definitly wouldn't consider myself experienced on them. I don't know which would be better a gsxr or a cbr? Also am i just putting to much thought into the size, or would a 600cc bike be ok? I know it would be faster than I have now, but I don't think it's necessary to drop to a 250cc. Any Advice would be really appreciated.
