Well, you guys have confused me.
There's a whole heap of 2nd gen owners who have chucked the radial MC, along with calipers as well. I replaced my m/c on the 2nd gen with a 'Braking' radial m/c and there's been a noticable improvement. I wouldn't waste my time on the 2nd gen m/c, considering it also had a recall from Nissin (although you had to push it to get them to replace it). I.e. if you buy a 2nd hand one, it might be one of the shit ones, it might be one of the good ones, it's a lucky draw.
Yeah, the 2nd gen brakes are better out of the box, but not by much.
1st gen = super shit
2nd gen = reasonably shit.
Why upgrade from super shit to reasonably shit, when you can just go to reasonably good with an aftermarket m/c, then super good with different calipers.
Ok, so that's my than 2c, but hey ... opinions are like assholes, everyones got em.
