A Note on Specification and Model

For Kid Kart racers currently, the full model designation for competition is the Honda GXH50 UT QXA. In previous years (prior to 2014) there was a model noted as the Honda GXH50 U QXA. This has been discontinued as of 2014. This was primarily done to reduce emissions from the engine, as this engine is utilized in a variety of applications, not just racing.

We note this information as some customers have specifically requested the Honda GXH50 U QXA, and wanted to inform racers that this model is no longer produced. The UT QXA now supersedes it.
