RIVE is an entirely new approach to the 4-wheeled motorcycle. The RIVE uses simple linkages to allow the wheels and rider to lean at will, completely independent of the suspension system. The wide stance and leaning technology doesn't allow the RIVE to fall over and you won't go down sliding out in a turn. Plus, it's a blast to ride!!! What you are seeing is the prototype we just started riding. More video's to come. The leaning technology of the RIVE can be easily adapted to a 3-wheeled motorcycle, in either 2 in front or 2 in back configurations.
