Chain 428 ProX MX – 130 links, unsealed (motocross)

Chain without sealing rings. It has the lowest friction and weight of any type, so it doesn't rob power — which is why most motocross riders run one. The trade-off is maintenance: nothing holds the lubricant in the pins, so it needs regular greasing and won't last as long as a sealed chain. Size 428, 130 links, ProX MX series. Supplied with a connecting link. From the workshop: always replace the chain and both sprockets together. A new chain on worn sprockets destroys itself in a fraction of its life. SKU: 07.RC428130C.
