We were somewhere around Barstow, on the edge of the desert, when the

Cheap and simple to make, can handle large amounts of torque, suitably
designed. Of all the advantages, none holds more sway for the makers
than the 'cheap' bit.

One of the reasons I got rid of my RS was the dry clutch. Ok it wasn't
slipping and had done 50k miles but I was doing a lot more stop/start
commuting and by what I'd read those clutches don't take kindly to a lot of
that. The BMW clutch is a real task to change, apparently (according to the
people in the BMW forum I used to frequent) BMW would charge something in
the order of �700 + to change it and an independant would be at least �500.

Rusted and ropy.
Dog-eared old copy.
Vintage and classic,
or just plain Jurassic:
all words to describe me.

Dry clutches sound great when they're rattling like a bag of spanners.

I've seen a Ferrari F1 engine dismantled. It had a multi place dry clutch
with carbon fible plates.

Clutch failure on boxer twins is not a big issue, for R-GS owners at least.
Not even amongst the mad sods who go off roading and will give their
clutches a harder time than road riders.
