Needing Advice... My son just turned 15 and is wanting to get into Road Racing. We have sold our Sprint Cars and are looking to go 2 wheels. He’s started in Karts at 4 years old. He weighs 165# and stands 5’11” he works out everyday and is very strong for his size. He knows his way around the R6 and GSXR 600 engines since we ran them in our Mini Sprints. He does ride Mx bikes so he is not unfamiliar to 2 wheels. He is prepared to put in all the class time and practice time to get licensed. We are firm believers in seat time. I’m needing to know what size and class of bike do y’all think is a good starting point. Thanks
