Can anyone help with parts numbers please - looking for a used shift assist unit for a 2016.5 GS: is the same part 8543012 used across all WC GS’s from when the option was introduced ie all 1200 and all the 1250 models up to 2023? So I can buy any used unit from any year? They all seem to have the same part number but some A105 or A103 after this?
GSAP quick shift assist thingy…
- Thread starter Max-GS12
- Start date
Not teaching you to suck eggs but have you used Real OEM to check part numbers?? It will show you what parts are used on across all bikes

Not at all - thanks very much. 
It seems to be the same part on all the 1200/1250 and RT (guessing that is a 2019 catalogue so only shows model runs to 2020?):

I don't suppose the A105 or A103 is relevant though - just a batch number or similar?

Also worth just checking with Motorworks as they do second hand stuff
www.motorworks.co.uk

Motorworks stock a great range of parts for your BMW motorcycle.
Thanks again - there are a few on eBay around £200 but Motorworks seem cheaper. Doesn't include the spline/bolt/washer (23418556234) but maybe best to get this new anyway as just quoted £8 for the fitting kit.

If your retrofitting,
ie not replacing factory fitted, most insurance companies see this as a mod ( so should be declared )

Anyone help with a stupid thing that has me stumped - how do you get the cap off the GSAP plug?!! Driving me nuts! Normally there is a clip or sprung plastic bit but lying awkwardly trying to work it out has me flummoxed - there is a grey bit that looks like it should release it.....
Is there nothing in the Service Manual you have??

Some of the BMW wiring plugs have a grey tab. From memory, you have to squeeze these in and pull them up with your nail and then the plug will release.
