Does number 41 sprockets work with 420 chain?
Yes, #41 sprockets generally work with #420 chain because they share the same -inch pitch (distance between pins).
While compatible, a #420 chain is slightly thicker and stronger, so it may feel slightly looser than a #41 chain on a #41 sprocket, but they are often sold together and considered interchangeable for many minibike applications.
Compatibility Details
- Pitch: Both chains are inch
- Roller Diameter: Both have a -inch diameter.
- Width: A #420 chain has a wider inner width than a #41 chain, so it will fit on a #41 sprocket, but a #41 chain might be too tight for some #420 sprockets.
- Usage: For high-performance, #420 is preferred, while #41 is commonly used for lighter duty.
On Facebook, users say that #41 and #420 chains are often considered compatible. However, some Reddit users note that while they are generally compatible, the #41 chain is thinner, and using it for higher-stress applications might not be recommended, with other Reddit users mentioning that the #41 chain might stretch faster.
Differences to Note
- #41 Chain: Lighter duty, thinner side plates.
- #420 Chain: Higher power/strength rating, thicker.
- #40 Chain: Heavier duty than both. A 420 chain will NOT fit on a 40 sprocket (too narrow).
For best performance, it is ideal to match the chain to the sprocket, but #41 sprockets are frequently used for both #41 and #420 chains in go-kart and minibike applications.
