My son is 8 years old and has been riding 2.5 years. He now rides a TTR-90 with a Big Gun pipe and modified air box. He does not race, nor has he expressed a desire to race, just ride with his friends and dad. He is not an aggressive rider, but he does like to go fast with caution. We ride on our own motocross track which has several small doubles, whoops, and 2 tabletops. He does not clear the doubles but does jump the tabletops and the backside of the doubles. We also have some fire lanes woods trails we ride. He is ready for a new bike. I don't want to get him a XR80 because it will be too small in a year. The XR100, DRZ125, KLX125, and TTR-125 are too big now and weigh a ton. This is my question. Is a 65cc 2-stroke too difficult a bike to learn the clutch process and is the high revving engine suitable for having fun? I have heard several opinions at the dealarship but if anyone in the forum has been down this road I would appreciate some info.
