So the Yanks can ride in Winter

[Richard]

And here is a very nicely modified BMW to prove it.  I knew that reverse gear was available for Urals but had never heard of a rebuilt Beemer gearbox.

I always thought the main problem was that synthetics are too thin.  Don't have to be I suppose and if I could get a 20/50 synthetic I can't think of a reason not to use.  I wouldn't mind........better off with tractor oil from my local shop.  Many years ago when money was tight I woulod drain it out of my Beemer and put into our 2CV.

If a bike needs synthetic how do you travel in out of the way places ?  KTM anybody ?

The good thing abut synthetic oil ls s that it is thin but don't get much thinner as it gets hot. So you have the best of both worlds little drag when cold and still has some body when hot. The mineral oils are thick but will thin out  a lot under heavy work or hot climates
