I heard about an option for the oilheads (GS or GSA ???) with a different gear set providing a slower 1st speed.

I will change my clutch next (Canadian) winter and will have the gearbox removed. If it's possible, I'd like to change the 1st speed pair (If the price is reasonable) to have a 'crawl' speed.

Thanks for any informations.

Found everything I needed to know here : MAX BMW Motorcycles - BMW Parts & Technical Diagrams - R1200GS ADV 08-09 (K255)

The option was available up to 2008 on GSA. I'll check if the gearbox is the same as the 2009 GS and I might be able to do that. I also found that some police model have a 'walking pace' 1st gear.

I seem to recall some options on final drives too, ratio is stamped on them. Gearbox would be better for a wide ratio to help at low end and interstate speeds.

One of the benefits of chain drive.

Found another option, replacing the gearbox by one from a R1200RT-P (police version). They are remored to have a very low first speed for parades, allowing to follow a marching pace without slipping the clutch, it makes sense but have to be confirmed. I should also find if it's standard police issue or an option.

I have found one on eBay at a reasonable price. If I can confirm the information, I'll get it.

I'd love to know the answer to this question!

A call to your local friendly BMW shop should be able to confirm. I do know the GS/GSA ratios are different and the transmissions are a direct swap. Much easier than and probably more cost effective than an transplant.

If the R transmission works that good news too as the entire R bikes go for cheap. Buy it for the transmission and sell off the rest for parts.
