Quick on-bike adjustment - with included molybdenum steel chain breaker
Chain breaker is made from molybdenum steel and is suitable for 420, 428, 520, 525, 528 and 530 roller chains. The tool reduces load on breaking tips to prevent premature wear during pin removal.
On-site shortening or re-linking becomes practical without specialist equipment, so chains can be sized to fit mini bikes, pit bikes and go-karts quickly.
Longer wear life - thanks to high-quality alloy-steel 420 roller chain
Chain No. 420 uses alloy-steel plates, rollers and pins with a robust construction described as heavy and durable. The design uses inner plates and rotating rollers to reduce friction at each pin.
Greater resistance to typical off-road abrasion and impact helps reduce replacement frequency during normal riding conditions.

Chain total length measures 59 inches and includes 132 links, pitch 1/2 inch, roller width 1/4 inch and roller diameter 5/16 inch, with sprocket thickness noted at 0.227 inch. Links are removable to shorten length.
Suitable for a wide range of small-displacement machines and straightforward to adapt for 110cc–125cc dirt bikes, ATVs, scooters and go-karts.
