I want to get a new chain for m pit bikes. I know my ssr sr 125 has a 420 size chain. Im unsure how many links though that would help.

I also have a 160 tr that I want to get a chain for.

What size does it take and how many links?

You just need to cut it down

The R1 Works Chain has the following features:

  • Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance

  • Chamfered inner links to reduce the chance of chain derailment

  • Extended bushings to reduce friction between outer and inner link plates, maximising power output

  • Chromised bearing pins for excellent resistance to wear

  • Gold colour side plates help prevent corrosion

  • Most perfectly matched chain for Renthal chainwheels allowing maximum power at the rear wheel.This also extends the life of both the chain and chainwheels420 x 130 links
