Monster Moto used to file "executive orders" to ARB (formerly CARB) annually as required under the Green Tag list (pollution compliant) but stopped.
Their last filing was this model year for their
MM B105 and
MM B80 bikes, but that was cancelled. Why?
They filed for the 2017 model year on the above bikes, as well as their
MM B 212. There was no 2018 model year filing for this bike however.
The requirements are simple. A few emissions tests and a two page form letter.
I have not found where CA made mini bikes illegal, or any evidence of law changes.
If I lived in CA and purchased these types of bikes, I'd have already called Ms. Veronica Longhi, (626) 575-6642 who is the Off Road Vehicle representative at ARB. I'd also call Monster Moto and ask them what is going on, provided I could reach someone who actually did know. Something tells me that answer is known by their corporate investors in Dallas.
Here is the link to the
Certification Program in CA which shows testing criteria, as well as the information above. They would know if Mini Bikes are illegal in California.
