I need advice from experienced riders, I bought my first dirt bike a 1997 cr125r last september. It runs great, the only thing is I'm 6'3" and 190lbs. It sags so low when Im on it, I feel like its not big enough. So this is what I wanted to ask, 1. What spring rate do you think I should buy? 6.3kg? 6kg? 2. Should I just sell it and save up to buy a bigger bike like cr250/yz250? 3. Compared to cr125, are the cr250/yz250 bigger in overall size? Do you think for my size I should just get a bigger bike? Thanks, I'm very new dirt bikes and I don't know who to ask about them.
