It depends on your motor and the track. In the 1/10 2WD buggy class, racers gear by final drive ratio: 6T and below near 9.40, 7.5–8.5T near 9.22, 17.5T near 6.48. On the Cougar Classic's stock 86T spur that is about 22T for 6T and below, 23T for 7.5–8.5T, 32T for 17.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Cougar Classic selected.
What is the internal ratio (transmission ratio) of the Schumacher Cougar Classic?
The Cougar Classic has an internal ratio of 2.43:1. Final drive ratio = spur ÷ pinion × 2.43. With the stock 86T spur, a 18T pinion gives an FDR of 11.61 and a 32T gives 6.53.
How many teeth is the stock spur gear on the Schumacher Cougar Classic?
86 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
