A hands-on garage tour with Ustad the mechanic. You can spin, zoom and take apart 3D engines, run the four-stroke cycle in slow motion, follow oil, coolant, fuel and exhaust, compare engine layouts, and put three Royal Enfields on the dyno.
Best on a laptop or desktop. In 3D views: drag to rotate, right-drag or two fingers to pan, scroll or pinch to zoom, click parts.
