I ended up taking the leap on a Kuberg.
I dont pretend to be a trials expert. Ive never owned a trials bike. I learned to ride at age 26 on an 88 CR500.
My boys are already riding on a XR70 (8 year old) and XR50 (5 year old). My youngest isnt getting up on the pegs. So the XR50 was sold and the Kuberg will replace it. My hope is to get him up on the pegs on a lighter bike without him getting distracted by the engine.
We will see how it goes. I'll likely start a new thread to follow my Kuberg experience.
