No doubt about the positive effect of this gyroscopic force on lower weight 
machines. The term 'panic rev' applies to a motocrosser that gets (too) out 
of shape in the air. The blast of throttle will help to right the bike.

Also, when the 4 stroke mx bikes came became competitive in ' 98 &' 99 much 
was made about the effect the higher weight of the reciprocating mass had 
on handling, both in the air and in turns. Previous 2 stroke riders 
initially had difficulty getting the big 4 strokes to turn well because the 
higher reciprocating mass/gyroscopic effect tries to right the motorcycle.

Obviously the same principles apply to our ST/RS's but the physics at work 
here have less of an effect since our bikes weigh 2.5 x more.

FWIW,
