It’s easy. Just get going at a nice rate of speed, 30–60 mph (48–96 kph). Keep the bike vertical, without leaning left or right. Then take your left boot heel, put it on your centerstand tang, and press down, hard! A huge stream of sparks will fly behind you, and you’ll laugh like a maniac inside your helmet. Do it enough and you’ll grind the entire stand into uselessness and discover the high cost of replacing it. Which will be totally worth it.
