Sam, must have missed the MX reference in your bio. Yes, MX is good training for karting. A few people claim karting is a step down. A lot of TaG and shifter guys seem to be MX guys who got tired of breaking bones.
Brandon, a “MY09” is just the designation for the most recent version of the Leopard (model year 2009). The revisions are reliability oriented and performance between the years is the same.
