Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor. Not published means it exists but no source we could find prints it.
How these numbers were settled
A 1/10 electric 2WD buggy kit released in June 2024.
- Kyosho's Technical Data gives an 8.23:1 gear ratio and a rear tire of 86.5 by 42mm, while the front measures 84 by 28mm, with a weight of about 1,450 grams.
- The kit includes a pinion gear, but Kyosho does not print its tooth count, and the spur count and transmission ratio are not published.
- The motor, speed controller and battery are sold separately.
