About Us


The RCM Shop is a machine shop in northwest Wisconsin, where we like to:

  • Make new "old" parts for vintage bikes, including:
    • Mufflers
    • Brake stays
    • Chain defense
    • Triple clamps
    • Spacers
    • and lots more!
  • Repair parts that "have issues"
  • Work on "those special projects" for our customers

Our focus is on twin shock motocross bikes from 1976 through 1980, including:

  • Suzuki RM
  • Kawasaki
  • Honda
  • Yamaha

But we invite projects for all bikes!

We also provide parts for FOX SHOX and SIMONS FORKS, as well as a range of miscellaneous parts, including shafts, bearings, and helpful tools, such as our special fork dampening rod restraining tool. (If you've ever struggled with removing the screw from the bottom of the Suzuki forks, you love this tool. It makes the task very simple.)

The RCM Shop is an extension of work done while racing and running a very small, motocross-focused shop between 1975 and 1979 in the Muscatine, IA area (albeit with a different name).

During that time period, I raced in AMA District 22 (Iowa), plus Milville, MN, Rhinelander, WI, Princeton, IL and St. Peters, MO.

You can find our complete range of current stock on eBay. The following links provide quick access to our current eBay listings:
