I am parting out my Mod 110 to start a ttr project, and I want to buy a YZ85 and a TTR125 and mix them. So obviously it can be done and I have seen a lot of TTR's with YZ85 forks, but I am wondering if anyone has used the swingarm, shock and rear wheel setup. Or, if it might be easier to just put the TTR motor in an 85 rolling chassis and make some motor mounts. I want to build a bigger bike that I can race in 4 stroke unlimited, but I want it to feel like a play bike/pit bike. Also might motard it. What do you think?
