It probably just comes down to if your patient or not. I personally wouldnt pay 800 for the 125 because I watched a few auctions before I bought and I saw a lot of 140xr's go for around the 900 mark at auction. The 140xr is a WAY better bike, Better suspension, faster, better tyres. Just to buy the suspension alone would cost hundreds of dollars. I heard a story that 125's wernt on ebay at the moment but I could be wrong. I only bought a 125 cause i wanted the same size as my bro in law so I can race him. When I was researching on here I found that people had good things to say bout dhz and pitpro and it really came down to personal preference in looks. I say if you want a pitpro be patient and get one at auction, you'll save money that you can spend on mods. It only took me about a week to get one at my price even if you only save $100 its better in your pocket than someone elses.
