SIDECAR, ANYONE ?

Posted on by
Darcie spotted the sidecar the moment I brought it home in the back
of the pickup truck, and proudly informed us that it was her car!

A reader asked about the sidecar I attached to my Shovelhead back in the mid-’80s, which sent me off on a daylong squirrel hunt. As I didn’t have access to the interwebs way back then, I had a hard time learning anything about the sidecar. I knew it was a ‘Zephyr’ brand unit, but after that my search for info hit a brick wall.

I nicknamed it ‘Moon Unit’ because it looked kind of like a space capsule, but it was actually pretty well-built, with the rollbar-style cage around the body, a weatherproof roof and windshield, comfortable bucket seat with seatbelt and legroom enough for most adults, storage space behind the seat, and room for a dashboard-mounted stereo if one was desired. I personally consider a sound system on a motorcycle an abomination – I mean, who needs a stereo when they have the sweetest music in the world echoing out their exhaust pipes? – but I might have made an exception for the sidecar, if it would make Darcie happy..

However, in the course of researching the sidecar’s provenance and history I did come upon the United Sidecar Association, and founding member Hal Kendall. I joined USCA and purchased a couple of sidecar manuals Dr. Kendall had published. Looking back, I know I could not have gotten the sidecar safely and properly mounted on my Shovelhead’s OEM Harley-Davidson wishbone frame had it not been for the good doctor’s manuals, which are still available, as downloads, at the USCA’s Sidecar Tech page.

Another essential to my task was the assistance of a motorcycle-savvy welder named Bill Mading, who owned BG&T Welding in Austin, just down the street from the cop shop. Bill was a dirtbike racer, which meant he understood the stresses and strains motorcycle frames must endure, and how to compensate for them. However, he was also a skilled enough artisan that he could weld aluminum and aluminum-alloy engine and transmission cases – not an easy trick, as those metals tend to warp from the heat of the welding process. Warped cases means uneven gasket surfaces, less-than-perfect seals between case halves, et cetera. Bud (Bud’s Motorcycle Shop) used Bill for all his delicate welding needs, and we never had a problem with a part Bill repaired.

Bastard applications call for bastard engineering. Between us, Bill Mading and I designed the lower mounts for the sidecar. At the rear we installed a vertical plate near the frame’s dovetail, which included a pin-style electrical connector for the sidecar’s lighting. Up front we replaced the OEM mechanical brake foot-pedal mount with a larger plate that could accommodate the mounting tabs we’d devised.
NOT PICTURED: The top front mount was the OEM Harley-Davidson clamp assembly. I also replaced the standard front-fork triple trees, shown here, with Harley’s OEM adjustable rake trees. For added stability and handling I added an OEM steering damper, as well.

Between the manuals I’d received from Hal Kendall, and Bill Mading’s dedicated assistance, we were able to devise a bastard set of mounts for the sidecar. They weren’t pretty, but they by god worked! See the photo below for more information.

Everything one needs to mount an off-brand sidecar to an OEM wishbone frame.

I didn’t have the interwebs back in the Dark Ages of the 1980s, so finding out what I needed to know involved scouring magazines for any mention of sidecars, writing letters that were often ignored, calling long-distance (remember those days?) and running up my telephone bill, et cetera. Today? Ten minutes with a mouse and I had already gleaned scads of information! In fact, the first site I visited told me where the Zephyr was manufactured, and by whom, and even had a photo of a pretty snazzy brilliant yellow Zephyr sidecar!

ONE FINAL NOTE: If you are at all interested in sidecars, please consider a membership in the United Sidecar Association. It’s money well spent, IMO, and support for a great organization.
