Description
xOverview
The MRELC 420 Jackshaft Chain Kit is built for durability and versatility on a range of popular mini bikes. Crafted from alloy steel, this kit pairs two chain lengths with practical tools to support on the trail and in the workshop. The result is a dependable system that stands up to regular use and demanding riding conditions.
Two chain lengths address different drive configurations. The shorter 42 link chain serves as a compact drive for jackshaft applications, while the longer 90 link chain covers the other portion of the setup. This arrangement helps riders adapt the drivetrain without hunting for parts everywhere.
