Working on a new project. All the guys I ride with constantly harass me about trying a real motocross bike with more suspension and skinny tires. Found a great deal on a barely used 2006 CRF150F. Had sat in a friends garage for years. Those years took a toll and after a lot of bad fuel issues have been fixed, the bike is nearly ready. Still looking for a stock arrestor assembly to put back in the muffler. Gonna have to replace tubes and tires before I can really trust it. Should I go Shinko 241 on both front and rears if I can size them right? Or should I put a knobbier Shinko on the back?
