I was invited to visit the seasons opening Sidecar MX in Holland by a friend, because his 2 sons (10 and 13) were racing their TT-R125. They really struggled in the deep sand, and the field was everything from full 450's to aircooled 125's so they knew 1st was out of the question. However, there were a few other Yamaha 125's, a 225 and some Honda CRF230's that matched their speed. It was really fun to see these kids go round!!
