Hi Jeff,

I must have a picture somewhere, but ont a digital one. My 75/5 was some sort of curry-coloured and it had a toaster tank. Beautiful bike at the time, and a wonderful ride with its short wheel base. The 750 engine was the best boxer engine ever made by BMW.

best wishes

Alfons

Hi Alphons - welcome from another new person here.

Its no wonder we like our Airheads here........

Welcome Alfons.

Hi Alfons

Welcome from down under. I have a mate (Mal/7) who I know would love your /7. His /7 is a 78 with single disc. He is in the process of converting to twin.

A sign of relief when I read your quote above. In a recent accident on my 78RS I damaged both of my Staintune 40mm headers. They were replaced with Staintune 38mm headers swaged out to 40mm at exhaust port and muffler (Staintune cannot source 40mm SS tube anymore). I have been concerned about loss of HP, not that I have noticed mind you. You have eased my concerns somewhat.

Oh no! BMW participated in marketing hype, back then? Colour me disillusioned.

Gidday Alfons from far away Oz,

I love the bikes with red being always a good looker on an old beemer, so well done with them both

So Germany hey, at last I can finally get someone to source me a good secondhand final-drive for my RS, box it up with special beemer care & send it off to a far away land well I thought I'd ask, no use beating around the bush here

Welcome into this mad house of twisted souls & pull up a comfy chair somewhere around the table......Enjoy

Willkomen, schön Maschinen!
We need more Germans. Please help us find more of your kind.

I'm just trying to imagine a Harley Club in Deutchland without chap wearing, leather vested Americans in it.
