DS250 for a 7yo?

[DerekM]

My son is 6 turning 7 and I desperately need to get him a new quad. He started when he was 3 on a Chinese 110, I moved him up last year to a larger frame apollo 125 but he has destroyed it! I have honestly put this bike back together countless times and all non important pieces have been removed after they were destroyed. He rides it to its limits already and it cant take it. I am looking to get him a quality machine I wont need to work on more than ride. I have been looking at the polaris sportsman 110 but i HATE polaris and honestly feel his skill level is either above it or will be by next year. I am seriously considering a ds250 but worry a bit with the open wheel wells and physical size as my boy is not a big kid. I am wondering if this is a good move or if anyone has a better option for me to consider? We mostly ride rough backcountry trails with some sand pit fun thrown in.

I picked up my 9 year old son a 250 timberwolf.  I think it's best that kids learn how to listen to a motor and shift gears.  He started on a DS90 than moved on to this.  Also that bike looks too big for him as he can barely touch the foot pegs.

Also I think for his safety on a quad he needs to know and understand the potential consequences of riding a too big for him bike at the rev limiter and what could happen if those tires grabbed and flipped the bike on top of himself.  I just don't want to hear of something bad happening.
