Is this still performance riding 101 ? ? ?

Just kidding!!!
Power up shifts without using the clutch...

It is infinitely easier with GP shift...
Down shifts on the other hand... Must use the clutch to be smooth...
If you still want to try to down shift without the clutch, shift after doing most of your braking...
Or get a slipper clutch, if your bike does not come with one...

PS: Or you guys can get a quick shifter and never worry about letting off full throttle...
