Grunge brush ok for 6th Gen Chain?

Recently while reading my owners manual (2003 VFR800), I noticed it said not to use any sort of brush to clean the chain as it will damage the o-rings. Is this true? If so, how is it recommended to clean the chain?

 

The only reason to avoid a stiff brush is that it could potentially inflict damage to the o-rings by wedging between the o-ring and its mating surface.

Presumably this could result in either physically damaging them or by allowing solvent in and hence washing out the grease.

I cannot comment as to the validity of this idea- I'm more of a premise guy

I suppose its possible. So there.

If you're concerned- which you seem to be...

Try what I did:
Spray solvent such as Motorex or kerosene on the chain. Use an old toothbrush and follow up with rags.

I'm thinking the softer bristles are less likely to cause damage. It is possible one of those fine little fibers to get wedged somewhere and fall out- but I cannot recall that ever happening unless I felt a snag- and never while cleaning an O-ring chain

No missing bristles- it's just a splayed ex-brush afterward... And my mouth tastes like blood. I think that means I needed it or its just a horrible flashback. Anyhoo...lol

In using a grunge brush I would say just apply less pressure down between the links- but scrub away on the side-plates.

 

You could use a stiff bristle paint brush with kerosene. Or just liberally spray pn some chain cleaner and wipe with a rag

 

The chain on a 6th gen VFR800 is pretty much the same as any 530 gauge o-ring chain on any other road motorcycle. Personally I am comfortable with using a properly designed chain scrubbing brush on my o-ring chains in conjunction with a rag and some kerosene.

From the Regina web site: "When the accumulation of dirt on the chain (sand, mud, asphalt particles or other foreign materials) is excessive, the chain must be washed with a brush and kerosene."

Brushes are safe as long as the bristles are fairly soft.

 

For what it's worth I've been using a chain brush made for modern chains for years and my chain is in good shape. '09 6th gen. I would say avoid using a brush if you don't have to, but if you get a really nasty chain for some reason I'd say the above advice to just not go too crazy with it is good.
