Ok so, I have a 2010 yz125 coming out of the shop in a few days. I'm so tired of it breaking down on me. I do a lot of maintenance only bike. I guess it's wear and tear. Bt, I'm thinking about becoming more serious about racing. Do I sell my 125 and get a 250? Or keep my 125? I love my bike, it's a blast and you get noticed more because your the only bike that is high pitched and is screaming by. I love the attention too. But, I think a four stroke would be more reliable. What I would really lIke to know is what's going to save me money in the long run? My 125 or a 250f?
