Why doesn BBR do steel frame conversions anymore?
Over the years, we’ve modified hundreds of CR80 frames to fit the CRF/XR80/100 motor. Because of the steel frame design, several compromises must be made to fit that motor. Our aluminum frame doesn’t have these problems. As a result, we have completely stopped doing the steel frame conversions. When you add the cost of all the extra parts (that don’t come with the other guy’s steel frame conversion), the cost of the aluminum frame is quite good.
