I have been looking at the different conversions that people have been doing with the TTR125's. Has anyone seen a TTR125 engine put into a YZ or CR 125 frame? My son is getting a little to tall for His TTR. But the power is good enough for trail riding that he likes to do. I want to get him a taller bike with adjustable suspension, disc brakes and a four stroke. Any ideas or info on this kind of conversion :thumb:
