Hi all,
Took my 2011 MC titanium tdci in to get the convers update at Lynford in Osborne Park.
I was told they could do it, but I would lose certain features and I would not be able to revert back. They could not tell me what those features were of course!! Could someone who has done the update tell me what I will lose in the process and if it's a problem?
Apparently a few people have not been happy with what they have lost?

Thanks!
