Team Corally Syncro-4

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 published means it exists but no source we could find prints it.

Gearing parts

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 (5 mm on the stock motor). Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

Corally's product page prints a 13T pinion, 46T spur, 3.31 internal drive ratio and 11.71 overall drive ratio, and the manual's speed gear chart (p. 8) marks the same 13T and 46T pair as factory fitted at 11.71.

• The manual's spare parts list names the 13T pinion C-72813 and the 46T cast steel spur C-00180-1261, whose part page lists the Syncro 4; the exploded view prints C-72713 for the same pinion, which reads as a misprint.
• Tire diameter is left blank because Corally prints three figures: 117mm on the product page, 114mm on the showroom page and 115mm in the gear chart.
• The 80+ km/h (50+ mph) claim matches the manual's chart for the optional 17T pinion on 4S (83 km/h), not the stock 13T (64 km/h), so no stock top speed is shown here.
• The manual gives factory diff oils of 20.000CPS front, 50.000CPS centre and 10.000CPS rear, and 500CPS shock oil front and rear.
• Length, height and weight are left blank because the product page (515mm, 185mm, 3400g) and the showroom page (495mm, 175mm, 3350g) disagree.
