I just want the motor from the XR/CRF 80/100. The chassis doesn't fit my son. If he was that big I would buy him a CRF150 and shed some CR85 forks on it. He has rode one around our field but its just to big for him....But I can't wait for him to grow into one. He doesn't have my drive to race, but he loves to trail and MX ride and loves the torqy four stroke's. He hated his KX65 and just quit riding. At least the SSR project has him wanting to ride again! I am just tiring of making it jump worthy for his weight. Heres the real kicker. I had a chance to buy a complete 88cc BBR, aluminum frame and all for $1500 and it was cherry!
