Sound deadening


Recommended Posts

Its not there just for sound deadening, its also there to absorb the impact should your chain, and or front sprocket decides to break and try and smash its way through the cover. A snapped chain will potentially smash a big hole in the crankcase.

It will and if you think a bit of polyurethane foam, that isn't directly in the firing line of a 630 chain travelling at 100mph, will do any good in that respect, you best buy a lottery ticket!

I was thinking the same thing, although I'd imagine that it would have some effect at lower speeds but having said that I'll take my chances and rip it out.
