KNM designs many of our own parts and we have combined them into the most requested and done upgrades on GY6 and CN or CF250 Scooters, Buggies and ATV's.
Each level kit is just a little better than the previous but also a little more challenging to install, in some cases. Although each kit's weight and spring choice is an educated average on most vehicles, (We ride and test them ourselves) your particular needs may vary some. However, all kits should get you much closer to your ultimate setup as described.


If you don't see the parts you're looking for, Please let us know. It's why we have so many of the parts you need now.
Thank you for your support!
