Did they change the pinion gear inside the mono FD?

The shafts were the same for the G/S's and the mono-levers. You can then get a mono-lever final drive (4 lug) and a GS hub ... lace it slightly off center to allow a bit of room for your rear tire ... and viola. FYI - That swingarm looks a bit longer than stock. It wouldn't surprise me if that rear shcok mount was added.

This is a great mod because it allows you to run a variety of final drives that were available in the R80's and R100 monolevers. The R80 G/S only had the one 37:11 which is perfect for dirt, but doesn't have much top end for highway speeds. I'm currently looking for the 33:11 mono final drive to do exactly what is above!

Just be aware, that there's a good bit of machining to do on a GS hub to make it fit a 4 lug mono final drive. Stephen Botcher's site has plenty of pics of what you need to do.

True true ... you have to lathe off a fair chuck of material from the inside of the hub. I haven't yet figured out how I'm going to accomplish that that one ... I do know a fair amount of machinists around here though. We'll see.

At least I've secured the hub!

Nope. Single GS style cap. Don't know what the tank is. I've sent a PM to Tony asking about this, & also what he did re the swingarm. I know he has 2 wheel sets, the 'motard' version & the 'dirt' version. He doesn't get onto ADVrider much.



Also that he is way quicker than me on Gravel...

It's the monolever. ...and the tank.

Imagine BMW nowadays accepting racing sponsorship from cigarettes and porn. Those were the days.

He was/is the local BMW bike dealer where I grew up. Most people considered him nuts for doing the Dakar. There was no GPS or radio back-up when he did it. Once he was lost for a while until they found him with a broken leg, if I remember correctly. Just checked, apparently it was head -injury and he spent some time in a coma. He is in his eighties.

some bike info on Marlboro R80GSGRrr

Hiya, a mate bought a bike with the tank on it,didn't want one that big so i had to help him out.
it had been crashed so took a bit to fix/ fit, and had to cut a second seat shorter by about an inch at the front. i also made new side covers so i didn't have to notch the originals. not quite as big as the plastics but still 40L. i don't have a clue where it came from originally.
Swingarm- HPN stamped on the shock mount and also on the bottom of the WP shock, 100mm longer than normal. it used to flex quite a bit. i notched it to fit the bigger tyre and braced it at the same time (i tested this with the orig wheel and definite improvement). yes it's a 11/33 diff and i got a cam made to flip the lever up.
as mentioned earlier, the centre of hub was machined out and rim moved across in relation to hub. a local legend did this with the original spokes as i didn't want it too far across in case it stuffed up front/rear illignment too much.
*when fitting a new tyre i cut 5 or so mm off the outside knobs to help with clearance - i just ride really slowly around right hand corners!

gotta rest a bit, lotta words for me. i can do a vol 2 if anyones interested but not much else major stuff.

cheers Tony

33/11 - that seems quite high for a dirty bike! No wonder you’re faster than Steve.

Oh, and good job getting that wheel re-laced locally! No-one I asked wanted to know, legends included.
