Hi I'm a new guy ready to get his first bike and pretty much set on getting the CBR125R. Just a quick question about it though if anyone can answer me. The wheels are awfully skinny and I think the bike would look much better with some fatter rims and tyres. Is it possible just to get some fatter rims and slap them on or is there some modification involved? I don't really wanna mess with the handling or dynamics of the bike however and not sure if changing the wheels will offer better grip or maybe make handling really bad? Any suggestions would be appreciated. Thanks.
