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 in some cases, also a little more challenging to install.
Although each kit's weight and spring choice is an educated average on most vehicles, (We ride and test them) your particular needs may vary some. However, all kits should get you much closer to your ultimate setup as described.
