Actually, no, it's a sport called motorcycle "trials".
Enduro is a sport that features mostly offroad type riding - not quite motocross, but in the same style, and one that features some on-road type racing as well. Sometimes enduro racing events take several days to complete.
Motorcycle trials negotiates barriers, as we've seen, and is definitely a non-speed event. Riders are deducted points for each time their feet touch the ground. The more difficult the barrier, the more potential points are at stake. The bikes feature no seats, are extremely lightweight, and have other elements (like large rear sprockets) that are designed for low, low speeds and less fork travel, unlike motocross bikes.
