What you have failed to comprehend is that nobody but you give a shit about arguing about ABS.
:hehehe
And yet here you are, doing just that
Let's get real simple..............cost-benefit..........you don't spend money if it is more than the value......you junk it!.
Did you actually read my post.
Maybe you go crying off to the BMW spares counter when something goes wrong, but anyone with any sense knows that there are a myriad of used spares specialists who will supply quality, and sometime reconditioned parts for a fraction of the cost of new.
I speak from experience.
I had a beautiful K1100RS before my LT.
The engine went bang.
Cylinder 2 overheated, totalled the piston and knackered the bore.
According to your logic, I should have thrown the bike away, but I didn't.
I found a replacement engine, and all was well again.
I did all that for well under the cost of buying another RS in similar condition.
Is it viable to fix an ABS system.
Well for under 100 bucks (see earlier link), and a few hours in the garage, I would say it's definitely worth giving it a go, rather than just give up, like you clearly do.
