i am told to brake my bike (rear) like ignition retard says.
2 strokes for life said:I gust remember a disscusion about hitting the brakes in the air and most said it does slow you down.
Papakeith said:yet another rumor beat down by a ruthless gang of facts! :)
The simple fact is that you begin slowing down the moment your rear tire leaves the dirt, regardless of the accelleration decrease on the face of the jump. You will also continue you to slow down to the apex of the jump and then slow down more(at a lesser rate) on your downward turn towards the landing. Aerodynamic drag is a huge factor in overall distance achieved but tapping the brake is miniscuel(spl?).ignition retard said:Come to think about it, you might slow down a little. The bottom of the rear knobby is subjected to relative wind whereas the top is not, therefore stopping the tire would create more aerodynamic drag . Of course this effect would be pretty minor
1st one is correct! Good job.High Lord Gomer said:For an instant, the part of the wheel (is that the right term in train-speak?) that is in contact with the track is not moving relative to the track surface (otherwise it would be sliding or spinning (LOL...smokin the tires on a train).
The linkage that drives the wheel at times is moving in a direction opposite to that of the train.
(Am I close?)
ignition retard said:I've found that when seatbouncing, the farther back I sit the more it throws me forward, sounds opposite I know, but I'm serious. Also the effectiveness of rear brake tapping in the air is related to how fast your wheels are spinning on takeoff. Too get a little scientific: The potential energy in your rear wheel is greater when it has greater rotational velocity, by hitting your rear brake you transfer that energy first to your brake caliper then the swingarm then the whole bike rotates the same direction the wheel was spinning.
as you increase speed u scoot up on the bike....if ur hauling and seat bounce on the main back of the bike...it katapults you and you endo...
