Chain and sprocket.

[Fazerider]

When you say the quieter front sprocket do you mean that it comes with the orange plastic thing as factory fitted. And does anyone know how it makes it quieter.
When I come to do mine this is certainly the way I will be doing it so to re lube the swingarm at the same time

I guess it cuts chain rattle as it cushions the link plates, it probably makes the sprocket less 'ringy' too.
Looking back through my records, I see I fitted mine in March 2012 i.e. 38,000 miles ago. So, no issues with longevity.
