Another thing I noticed is that a friends' 2008 YZ85 is a lot lower (completely stock)! I can't imagine that the factory setup on the CR would be that much higher. There must be something I'm overlooking.
In general, do you believe that the average (a bit on the tall side) 10 year old should be able to ride a 80-85cc MX bike?
My son started on a PW50 when he was 5, then a PW80 when he was 7 and then we upgraded to the CR80. He was basically destroying the PW80 so an upgrade was really necessary. Maybe the CR80 was too much? I must say, not because it's my son, but he is a really good rider (very smooth, like his dad). And honestly I believe he can handle the bike on the track very well. It's just the stopping part where he literally falls short (haha..). Except for an FMF pipe, the bike looks completely stock, so I find it hard to believe much has been modified on it. Anyway, any helpful thoughts are appreciated.
