MOTO-MASTER V2 420 gold Drive Chain - 130 links

The MOTO-MASTER 642001 drive chain. The chain transmits power from the front sprocket to the rear sprocket. Off-road, it works in mud, sand and water: a quality chain, correctly tensioned and lubed, keeps the drivetrain smooth and makes the sprockets last.

When to replace it?

• Chain that stretches quickly: you have to adjust it more and more often.
• Tight spots or stiff links when you turn it.
• Chain that lifts away from the rear sprocket when you pull it rearwards.

Replace the chain when the adjusters reach the end of their travel or as soon as it has tight spots, and always together with the front and rear sprockets if they're worn.

Fitting tips

1. Check the pitch (415, 420, 428, 520…) and the number of links of your original chain.
2. Shorten the chain if needed with a chain breaker, cutting at the end opposite the master link.
3. Fit the master link: the clip goes on with its open end facing away from the direction of rotation; a rivet-type link is riveted with the proper tool.
4. Set the tension as per the manual, with the wheel aligned, then lube with a chain lube.
5. Recheck the tension after the first ride: a new chain beds in a little.

Why MOTO-MASTER?

In motocross, Moto-Master was working with the Red Bull KTM Factory Racing team as early as 2010, and it backed the MXGP world championship in 2015. On the technical side, the Flame profile of its discs is designed to improve cooling and go easy on the pads, and its Racing GP sintered pads use a backing plate with hooks (NRS technology) that stops the friction material from coming away.

Frequently asked questions

Sealed or non-sealed chain?
An O-ring or X-ring chain keeps its grease inside and lasts longer. A non-sealed chain has less friction and is still popular in motocross, but needs lubing more often.

Should the sprockets be changed?
If they're worn, yes: a new chain running on a worn front sprocket and rear sprocket gets damaged very quickly.
