You may not be Batman, and Fido may not be Robin, but that does not mean you cannot speed into adventure together. In fact, a sidecar is one of the safest, most practical ways to transport a pet via motorcycle. Or if you are craving some much-needed storage space, a motorcycle sidecar is a convenient way to increase the footprint of your bike. Fans of big, American choppers can find universal models that fit both large and small Harley-Davidsons. Those who prefer Japanese engineering can match a Kawasaki or Honda sidecar to the sporty Japanese bikes. There are branded sidecars built to pair with a specific bike or brand of bikes, and there are universal options made to fit nearly any road hog. You can find a large selection of new and used bikes, sidecars, and parts on eBay. Remember that the rules of the road in some states require passengers wear helmets too, and outfitting your guest in comfortable motorcycle clothing is a kindness.
