Tires are a must, modified cam sprocket is a luxury.
I agree with your 3 points, but I also factor in how much it would cost to modify. I don't mind spending the money, I just don't want to get gouged just because it's a BMW. Some don't have the means to modify it and don't mind spending the money which is their choice. Being a machinist for 30+ years I know what it costs and not willing to spend that much which is my choice. Don't get me wrong I think it's a good idea, just a bit high on the price. In the end the only person who has to be satisfied with it is you, and what anyone else thinks doesn't matter one bit.
I wouldn't even mind if they were in the $125-$150/ range for a pair, because new from BMW they are under $60 each.

For me, the inhibitions are:
1. Does it really work?
2. Will it decrease the longevity of the bike?
3. How hard is it to install?
