[KITACO 535-1083340 Drive Sprocket Rear 40T 420 Size Monkey (6V & 12V) KITACO 535-1083340]
The timing for replacing a sprocket is ambiguous, with no clear standards.
One indicator for this is "tooth wear."
When the teeth become pointed, or the belly or sides are worn down, it's time for replacement.
Replacing the front and rear sprockets and chain simultaneously. If you only replace one of the three, the new part will not be able to perform or last as intended due to the worn unreplaced parts, leading to an earlier replacement. Therefore, considering the long-term, it's recommended to replace all three simultaneously for better longevity.
This is the rear sprocket (wheel side).
To enable detailed settings, it supports tuners with a wide range of tooth counts and reasonable pricing.
Made from highly durable chrome molybdenum high-tensile steel.
Sprockets are consumable parts.
As a general guideline for normal driving, inspect the sprocket every 1000km (regular lubrication significantly improves the lifespan of sprockets and chains).
Rear sprocket tooth count ÷ Front sprocket tooth count = gear ratio. A higher number indicates acceleration-oriented, while a lower number indicates top speed-oriented.
