My boys were both under 2. They worked the throttle (gover'ned down), & I had a rope on the ski loop to keep control of them.
By the next season they both were able to manouver the yard themselves.
Now my oldest (6) runs a 200cc mod (ski doo mini) with pipe, gear, clutch & jet kit. He is pulling about 25 miles per hour.
My problem now, is that his little brother (5) can't catch him (ZR120 pipe only).... Do you think the mods will ever end????????????
