Hey Y'all, I am a buck 60 wet and an intermediate (yet semi-agressive) woods/trails rider, and I am looking to get off the XR250 and into something faster. I have narrowed it down to the YZ250F and the CRF450. My experienced riding buddy thinks that the CRF (or any 450)might be too damn much bike for my weight/experience. Anyone out there who fits my profile that can help? Thanks!
