AFAM 428 Ultra Reinforced Racing Chain for Dirt Bike, Pit Bike
This chain is intended for heavy use on motocross tracks.
It guarantees you a chain of High Quality, lighter and called "Ultra Resistant" over time, allowing you to maintain your chain tension up to 10X longer than an original chain.
Used by the MXLABS Team and by Mini MX Amateur Riders. We highly recommend this product for all users of Pit Bike motocross tracks.
Number of links : 120 links
Chain pitch: 428 (See additional photo)
The AFAM Chain has a 428 pitch and comes with its quick link.
Compatible with all brands Apollo Motors, Bastos, CRZ, Gunshot, PitserPro, Mini MX, YCF, RSR, Bucci.
Reminder:
Chain pitch 420 = approximately 6.5mm
Chain pitch 428 = approximately 8mm
Advice:
- If you lengthen your transmission, you will gain top speed but lose torque/responsiveness of the engine.
- If you shorten your transmission, you will gain torque and lose top speed.
- Regularly check the chain before or after each ride.
The chain tension is done with a person sitting on the motorcycle; the chain must be tight enough to allow a finger to pass between the Teflon slider on your swingarm and the chain.
If it is too loose, adjust your chain tensioners to move the wheel backward; if it is too tight, adjust the tensioners to move your wheel forward.
