What pinion gear should I use on the Yokomo RO2.0?

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 RO2.0's stock 84T spur that is about 23T for 6T and below, 24T for 7.5–8.5T, 34T 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 RO2.0 selected.

What is the internal ratio (transmission ratio) of the Yokomo RO2.0?

The RO2.0 has an internal ratio of 2.6:1. Final drive ratio = spur ÷ pinion × 2.6. With the stock 84T spur, a 18T pinion gives an FDR of 12.13 and a 32T gives 6.83.

How many teeth is the stock spur gear on the Yokomo RO2.0?

84 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

Out of the box the RO2.0 runs 300 cst front, 250 cst rear (Yokomo oil), on 3-hole front, 3-hole rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.

What springs does the Yokomo RO2.0 come with?

The kit springs are Front (#Z2-FRST) front, Rear (#Z2-FRST) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
