About Niche IndustriesNiche Industries has been in the ATV, Powersport, and Outdoor Power Equipment parts market since 2011. We specialize in designing genuine OEM compatible parts at an affordable price and guarantee their quality as a replacement for your original parts. Don't Know Your Part's OEM Number? Did you know that using your machine details (year, make, and model) may not necessarily mean that the part will be compatible with your machine? It is important to ensure that our parts will fit your machine and to do so you need the right OEM number handy. To obtain the OEM replacement numbers, refer to the VIN (Vehicle Identification Number) details located on your ATV (typically located on the frame of the ATV with 17 characters - not to be confused with the engine number). Once you have located your VIN number, call your local authorized dealer and they will run your VIN number in their system to provide you with the exact OEM number for the parts you wish to order. Once you have the OEM number, please ensure that it matches one of the OEM number sequences listed in our 'Technical Details' section on our Amazon listing or in the bullet points mentioned on the products. Once the match is confirmed, click 'Buy now' with confidence!
