Drive Sprocket Front 15T 420 Size RZ50, TZM50R

[KITACO 530-0019215 Drive Sprocket Front 15T 420 Size RZ50.TZM50R KITACO 530-0019215]
The timing for replacing sprockets is very ambiguous, with no clear standards.
A key indicator for this is "tooth wear."
If the tooth tips become pointed, or the belly or sides are worn down, it's time for a replacement.
Simultaneous replacement of front and rear sprockets and chain If you only replace one of the three, the new part will not be able to perform at its full potential or durability due to the wear of the old parts, thus shortening its lifespan. Therefore, from a long-term perspective, replacing all three simultaneously is recommended for longer life.
Front (engine side) sprocket.
Made from S45C (high carbon steel), which offers light weight and high durability.
Sprockets are consumables.
As a general guideline, inspect your sprockets approximately every 1000km of travel.
(Regular lubrication significantly extends the life of both sprockets and chains.)
Rear sprocket teeth count ÷ Front sprocket teeth count = Reduction ratio. A higher numerical value indicates a more acceleration-focused type, while a lower value indicates a more top speed-focused type.
