This 1961 McCulloch R-1 go-kart underwent a refurbishment completed in 2021, featuring a yellow two-piece steel frame and a black vinyl seat. Power comes from a pair of rebuilt 87cc McCulloch MC-10 two-stroke singles, delivering power to the rear wheels via twin Hortsman Rev Grip centrifugal clutches. Notable modifications include a transistorized ignition, single-ring pistons, adjustable throttle linkage, a splined steering shaft, a 3/16" brake disc, and custom headers.
