You want to consider a weird partial trade? How about this;
It's a BBR frame, CR85 components and a KTM 105 motor. Work is mostly complete but the carb-to-airbox duct needs to be fabricated and the engine mounts were built temporarily to be sure the motor was placed correctly.
It has a 2.9 gallon CRF250X gas tank and all carbon guards. The frame alone is $3200 !!! Weight is about 160...
