Ratios for gearboxes and bevel boxes?

[DrAlf]

Does anyone know of a URL that shows the different ratios of bevel boxes and gearboxes fitted to the various different models of 8v boxer engined BM’s? If so, please post it!

Thanks in advance.

I remember someone posting them on the ADVRider site a while back. Try searching over there.

I can send you an article written by a close friend who has an 1150GS and worked out the various ratios of the different bevel drive options.

The upshot was that he bought an 850 bevel drive complete and swops them over depending on where he's going. I personally know 4 people with 1150 GS's that have done this option. To a man, they are all extremely happy with this conversion.

It's in word format.

Mick.

That would be great – exactly what I was after. I’ll send you an email now.
