Monster Moto: finding your numbers, your engine and your parts
You own one. Here is what the federal certification record says about who actually built it, what to look for on the machine itself, and how to search for parts when the badge gets you nowhere.

Who built the engine in your Monster Moto
Monster Moto, LLC is the name on the certificate filed with the US EPA. That is the company that brought the machine into the country, not the company that built the engine. Every Monster Moto certificate on the record names one Chinese engine factory: Lifan.
The numbers to find on the machine
Where these live depends on the shape of your machine rather than on the badge, so we do not repeat the search here — the sheets below cover it properly and are free. What matters for a Monster Moto specifically is which number settles things: the engine family number ties your machine to a specific federal certificate rather than to a badge.
- The emission control information label
Carries the engine family number. This is the strongest identifier your machine has and the one most owners have never looked at.
- The code stamped into the crankcase
Survives when the label has not. It encodes cylinder count, orientation, bore and displacement class.
- The VIN
Identifies the vehicle rather than the engine, and its first three characters name whoever registered it for sale.
Engine families on the record for Monster Moto
If the label under your seat carries one of these, it is a Monster Moto and this is the certificate it was sold under.
| Engine family | Model years | Displacement |
|---|---|---|
| EMNRX.080MMB | 2014 | 80cc |
| FMNRX.080MMB | 2015 | 80cc |
| FMNRX.196MMA | 2015 | 196cc |
| GMNRX.080MMB | 2016 | 80cc |
| HMNRX.080MMB | 2017 | 80cc |
| HMNRX.105MMA | 2017 | 105cc |
| HMNRX.2122M2 | 2017 | 212cc |
| JMNRX.080MMB | 2018 | 80cc |
| JMNRX.105MMA | 2018 | 105cc |
| JMNRX.2122M2 | 2018 | 212cc |
| KMNRX.080MMB | 2019 | 80cc |

The other names to search under
12 other US brands sold machines whose engines came from the same factory at the same displacement. When a search for “Monster Moto” returns nothing, these are the names worth trying instead.
How to search for a part
Searching the badge is searching the weakest information you have. These are built from Monster Moto's own record, roughly strongest first — replace <part> with what you need, and add the measurement you took.
- 1EMNRX.080MMB <part>
- 280cc <part>
- 3Lifan 80cc <part>
- 4American Lifan, Inc. <part>
- 5Monster Moto, LLC <part>
The strongest search usually has no badge in it at all. An engine family number plus a measurement finds listings from sellers who have never heard of Monster Moto, which is most of them.

What this page does not tell you
This record covers certificates whose engines were built in China. Monster Moto, LLC filed 27 certificate rows in total, of which 27 — all of them — are covered here.
It also cannot tell you that a part fits. A shared factory is a research lead — a list of other badges worth searching under — and nothing more. These machines are assembled from several component suppliers, and those suppliers change, sometimes inside a single model year. Why that is, and how to measure instead.
