Ktm-mounted sidecar motocross rider Jänis Sedlenieks and monkey Girts Indrijaitis roost their way through the dirt in Stelpe, Latvia. Sidecar motocross requires an unusual combination of athleticism, teamwork, and daring that set it apart from motocross riding. The forces that allow a sidecar rig to slide and turn would just as soon send it flipping over in the dirt. An active counterbalance is needed, which means a sidecar monkey is never just along for the ride. Similarly, sidecar motocross machines have evolved to be distinct themselves. Note the specially developed tube frame and the leading-link front end. It’s unusual, sure, but just like its single-rider sibling, sidecar motocross jumps are hairy and the on-track action is intense.
