Okay let me cut this short I'm 14 5f 4 and yes i know, I should be getting a 125 but the issue is there are no 125s for sale in the area at the price range I'm limited to. Basically my brother and I have been arguing he's 17 and wants to become a motorbike mechanic he usual services our bikes, hes okay with the Crf250r but not with the Rmz250 this is due to the fact the rmz has a big bore kit with 15ccs, the crf250r looks a lot bigger then the rmz. The old owner of the rmz i was taller then and they could touch ground in the bike, so personally i think the rmz is more safe because I wont be speeding on it at all probally not even past 3 gears for a long time. Thanks!
