This was mythird custom vehicle, and my last custom for nearly 3 years until I made v1.0 of the Fish Bone Ferry. Just like the early versions of the Jet Bike,Balancer was used to reduce the poly count of the full detail model. I haven't touched v1.0 in over four years, so I can't recommend using it.
v2.0 is a full remake using the mid/low-poly models from Mario Kart 8 Deluxe with a custom model for the Cyber Slick tires.
v2.1.1 added an alternative download with custom textures for each character. This was done because of the mod's planned usage in Mario Kart Wii: Limitless.
