How those gear's on a ttr 125 is it one down then the rest up?

Yes, on a Yamaha TTR 125, the gear shifting pattern is typically one down for first gear and then four up for the higher gears (2nd through 5th). This means you shift down to engage first gear and then shift up sequentially for the rest. The neutral is located between first and second gear. Always consult the owner's manual for specific details about your model.
