I have a 9-1/2 year old & he's almost 70 lbs. He started on a 50cc quad when he was 5, then moved him to a PW80 dirtbike about 1-1/2 years ago. He wants another quad & I'm having trouble deciding on what to get him. I think/know that the current 90 4S that are out will make him bored quick. He's not a racer, but is a good responsible rider. I was thinking along the lines of a mid size 2WD quad. From my searching I kinda narrowed it down to a Yami Grizzly 125 or a Susuki Lt160. I have posted elsewhere & have got alot of responses for Trailblazers & Blasters & other 200-250cc rides, but think he's not there yet---or maybe I'm not, LOL. I watched a lot of vids posted on YouTube to get a feel for both machines. Most vids actually have teens or adults on them, so I'm comfortable with their power. Anyone got any good or bad about them or another comparable model to look at? Not looking for a racer. Something that has enough torque to play in the woods & hills & is reliable. These look like they'd top out at 40ish...which is plenty. Thanks.
