I have a very good condition 2014 CRG RX28 chassis for sale, this chassis is designed for use in junior Rotax, it is extremely easy and forgiving to set up. It has never been crashed and the frame has never been bent.
With it is a 2013 Rotax FR125 junior engine. I purchased the Evo upgrade and am including this at cost. Separately I am looking for $2400 for the engine and $2900 for the chassis. Together I will sell for $4700. This is a true bargain.
