first 3 wheeler/ whats the shift pattern
Nope, neutral is all the way up.
Then you have 4 gears down (fourth is all the way down).
If it's an atc 125M, it should have a green neutral indicator lamp.
I know this because my first ATV ever was an atc 125m.
Then don't forget that down below, next to the left rear tire, you also have a switch which gives you the option for switching between H (hi) and L (lo) range. (for normal riding, I suggest you keep it in the H position).
Enjoy your machine! (I loved mine...until I outgrew it).
