Hi Guys,
The digression begins... The rear brake was not removed to shave weight, it was removed because I almost killed myself with it... twice.
I've had it off the entire year so far, and I can honestly say that it has been better without it. Say what you want about "training yourself to brake properly in panic situations" but for me, it was hard to resist the urge to mash that pedal when you really need to stop. On a road bike it's fine to lock the back wheel, but it's not fine on a motorcycle.
I would not suggest it as a weight saving measure, and I would not suggest it for all riders, but if you're like me, and don't feel comfortable having it there, then I don't think it's all that bad to go without.
Remember the 80/20 rule? Those guys weren't pulling on the front brake hard enough
Cheers,
Owen
