Is the S4-01077BA suitable for all YZ-4S versions?

This dog bone is intended for the YZ-4S family and is compatible with related chassis like B-YZ4SF, B-YZ4SF2-1, MOR-010 and MOR-020. Always double check your chassis reference.

How often should I check the dog bone?

Inspect the dog bone whenever you service the front end or notice play; early replacement prevents secondary wear to cups and pins.

Any setup advice for race days?

Carry a spare dog bone and basic tools, check coupling points between runs, and keep lubrication fresh to avoid unexpected driveline issues at the track.
