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 RB7 SS's stock 72T spur that is about 20T for 6T and below, 20T for 7.5–8.5T, 29T 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 RB7 SS selected.
What is the internal ratio (transmission ratio) of the Kyosho RB7 SS?
The RB7 SS has an internal ratio of 2.6:1. Final drive ratio = spur ÷ pinion × 2.6. With the stock 72T spur, a 18T pinion gives an FDR of 10.40 and a 32T gives 5.85.
How many teeth is the stock spur gear on the Kyosho RB7 SS?
72 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
