It depends on your motor and the track. In the 1/10 2WD truck class, racers gear by final drive ratio: 7.5–8.5T near 10.14, 13.5T near 8.27. On the YZ-2T's stock 80T spur that is about 21T for 7.5–8.5T, 25T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the YZ-2T selected.
What is the internal ratio (transmission ratio) of the Yokomo YZ-2T?
The YZ-2T has an internal ratio of 2.6:1. Final drive ratio = spur ÷ pinion × 2.6. With the stock 80T spur, a 16T pinion gives an FDR of 13.00 and a 30T gives 6.93.
How many teeth is the stock spur gear on the Yokomo YZ-2T?
80 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
