My 7 year old son is ready for a bigger bike. He has just about outgrown his PW50, and he is ready for a "real" bike with a working suspension. He is approx 48" tall and 44lbs. We have been looking at the KTM Jr Adventure. They are nice but cost too much. I've found some used 50cc race bikes which fit him well for much less. The bike I have in mind is a Polini which I can get for $1200. Sorry I don't yet know the year or model. I understand this is a race bike and is not suitable for trail riding. He will only be riding on a mini race track. Will the bike still cool and run OK if he isn't riding at race speed?
The main question is can I some how detune the bike to roughly 5hp until he gets some seat time? I have access to lathes and mills so I can make restrictors for the intake or exhaust if needed. Also, the bike is 2-3" too tall. Can I lower it somehow?
