Morning ride to work..

Usually newer riders don't put enough oomph into the shifter and the gear they miss is 2nd , but you can miss any gear. You really can't push up too hard with your foot when you shift gears, and you can't accidently get it into a higher gear until you release your foot on the shifter and the shifter returns to the original position. You can then shift into the next higher gear without ever letting out the clutch if you want to go from 1st to 3rd for example. Same with downshifting. I do that a lot when I will exit the interstate going 80 mph and find myself on a ramp with slow moving traffic. I just downshift from 6th to 4th or even 3rd, bang, bang, bang and let out the clutch. The Gixxer goes form 80 to 40 quickly...even quicker if you use the brakes along with it. There's no slipper clutch on the Grom though, so you won't want to go from 4th to 1st from say 50 mph and let out the clutch. That would cause the bike's rear wheel to lock momentarily and skip possibly causing you to lose control. 4th to 3rd would be fine though or maybe even 4th to 2nd at that speed to get the bike slowed down quickly.
