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.

Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft.
How these numbers were settled
Sand rail version of the Baja EXT, rear wheel drive with a 45cc two-stroke, so motor KV and cell count do not apply.
- Rovan RC names a 17 tooth pinion and a 57 spur gear and the same 220mm x 120mm Baja EXT tires as the EXT 5T.
- The rear diff tooth counts are not published, so the ratio after the spur and the final drive are left blank.
