    if i understand you correctly the corners question is about maximizing traction and power. what you are probably hearing is slipping of the clutch and then dumping as you call it once theres enough traction to power out of the corner.

    on the landing there are a couple of reasons for "nailing" it when you land. one is just racing...the sooner the wheel hits the ground the better as long as you are back on the throttle. other times you "nail" it are to help absorb a hard landing or straighten the bike out.

    you can roll the throttle on but that means you won't be in the peak horsepower range of the power band as well you might lose traction. slipping the clutch allows you to apply maximum power to the ground while maximizing traction.

    also right out of a cornerif you just let go of the clutch you will probably spin out, not good when you are racing there goes first, second, third, all podium spots and you will have to charge and hit every jump perfectly to get back in front

    also if you roll the throttle and have a finger on the clutch it is better than just dumping the clutch and falling

    English please? :)

    By "slipping" the clutch, does that mean that you have approached the corner with appropriate speed and as you are going through the corner, you pull in the clutch and keep the throttle revved as your are going through the corner? Then as you are coming out of the corner, release the clutch (dump the clutch) and shoot out of the corner?

    Don't mean to sound stupid, just trying to pick up on some of the lingo.

    Thanks.

    Yes. Approach the corner as fast as possible with the clutch pulled in. About half way through the corner, start to "slip" the clutch while applying throttle. It's a feel type process. A balance between power and slippage will allow you to exit the corner under maximum power for your particular ability. The better you get, the earlier application of "more" throttle you're able to utilize.

    To answer this part - you actually want to rev the more out just before you land so as to be applying optimal power immediately at the landing zone not to bog it out even the slightest bit. You'll hear a lot for 4 bangers hitting the rev limiters though - this is not what you want to do either. If your bike hits the limiter it is not performing at peak power because it is skipping a ignition stroke to limit over rev and possible engine damage.

    If you wait to land then hit the throttle you can bog the motor or achieve less forward velocity by not being at peak power. You want to be under peak power right from the landing to achieve maximum velocity into the next section of the track

    Also if you land in sand or just a down right poor landing gassing it hard will help carry your momentum an keep you from eating dirt - momentum is the key to racing!!!
