At Neff Design and Engineering, we are devoted to design and custom crafting of fine products. Nestled in the Dragoon Mountains of southeastern Arizona, our quiet, secluded workshop provides us with an environment and pace conducive to maintaining high standards of quality and integrity in all our endeavors. We stand behind every product we create, and your complete satisfaction is assured.

We currently offer four products/services:

1. Manufactured forks and sidecar subframes for both R-Series and K-Series BMW motorcycles. We can install a custom crafted leading link fork or do a complete sidecar conversion and installation.
2. Custom wheels: a line of 15-inch wheels utilizing automotive radial tires for both the R-Series and the K-Series.
3. BMW/2 final drive conversion: converts your 1955-1969 final drive to the more durable (and parts-available) version used on the 5/6/7 models. Ideal for sidecar installation or anyone who wants superior reliability for their classic BMW.
4. Universal electric shifter kit: converts motorcycle foot shift to thumb control for all makes and models.

We continue to develop new products and services to make riding safer, more reliable, and more enjoyable. Please contact us at the address below to hear about our complete line of services.
