Message: [QUOTE="robwbright, post: 1375544, member: 60515"] A double jump is two jumps spaced in such a way that you are meant to jump from the take off on the first jump and land on the down side of the second jump. If you come up short, you will hit the up side of the second jump and that can be painful as it can throw you off the bike. If you over jump the down side of the second jump you'll "flat land" and that can also be painful if it's a really big jump. A triple has three jumps spaced such that good riders will jump from the take off on the first jump, over the second jump completely and land on the down side of the third jump. A table top is essentially a double jump with the "hole" in the middle filled in. i.e. A tabletop looks like a table from the side - the take off, the flat part on top and the landing. If the take off jump is 3 feet high, then the middle "table" part of the jump will also be about 3 feet high and the downhill landing area will simply run down off the "table". Tabletops are very low risk because you're not really that high in the air - the table portion is just as high as the takeoff. Plus, there's no second jump to come up short and land into. Here's a drawing of a tabletop jump.

(it was the second time I ever jumped a double - almost crashed hard). [url]http://s175.photobucket.com/albums/w134/robwbright/?action=view&current=DSC08768.jpg[/url] That's not a risk on a table top, because there is no "hole" in the middle. Lots of doubles and triples in this video: [url]http://motocross.transworld.net/videos/video-ryan-dungey-450cc-supercross-testing/[/url] And BTW, whoops are a lot of little bumps strung together in a row - they can be really difficult to ride fast.
