Are you going to ride mx? Dessert?
If mx here are two different methods...
AIM and shoot! Not the fastest way though...
You line the bike up for the straights and go wot...
Or tried and tested method of throttle control, Keep it in the meat of the pwrband use the awesome power available to get up over the bumps and ruts early coming out of the corners, let the bike work for you don't try to wrestle it around.
Back in my 125 days I was pretty fast, but I wrestled the bike around the track, when I switched to 250 I wasn't strong enough to do that and had to adapt to a different riding style, I switched to the 500 after 2 years and had to refine my now soft riding technique even further, back in those days I was 5 ft 4 in and weighed around 125 lbs, someone said I was the smallest 500 rider in Sweden... Sadly I'm no longer that light... Pushing 200 lbs nowdays but I can still move a 500 cc bike around a mxtrack pretty fast making the young guns look foolish when they get beat by an old fat guy on a bike thats obsolete....
