Hi I have noticed the odd VMX post so have a bit of hope that someone can offer advice. I am fairly new to bike riding but have my heart set on racing in the women's vintage motocross. I am Looking for a first bike and have had a few suggestions but willing to consider further advice. Thinking 125 or possibly 250 and in the later 80's. probably a Honda CR or something similar. Any advice out there on a vintage bike, suitable for a 5ft 8 girl that won't be totally impossible to get parts?
