1.) The Kettenkrad is a neuter in German: DAS(!) Kettenkraftrad.
2.) Tamiya wouldn't put an article in front of the designation. It would be "Sd.Kfz2 KLEINES KETTENKRAFTRAD" (https://www.scalemates.com/kits/tamiya-35029-sdkfz-2-kleines-kettenkraftrad--103647)
This error is especially strange, since kirochef seems to know the illustration of the Tamiya-kit (see MG42 on the soldiers shoulder).

I'm oddly curious if the kettenkrad can be useful as a mobile gun platform for the MG42 or a mortar much like how the Kradschutzen employ the motorcycle + sidecar combo
