I have found that simply changing the lever to an ajustable one corrected most of the 'Wooden' feel.
Anyway, for my short fingers, the travel was much too far away from the handlebar to get any kind of feeling.
I doubt that BMW was afraid of front wheel lock since they use ABS.
I think it was a cost cutting measure, easily corrected through eBay and Chinese manufacturers of ajustable levers.
yes, for sure, adjustable levers are a must. not so much for clutch lever, since you want to open it pretty wide to be able going into the neutral, but for brake side it just a both comfort and safety measure. keeping the brake lever as close to your hand as possible, assuming that the set up is not too soft as for the lever to hit the handlebar, make such a huge difference. luckily, there are many cheap Chinese levers available of very good quality, short or long, which offer such adjustment. however, having this adjustment does not change the general braking feel.
as to the locking the wheel, ABS is the last salvation, which also may fail at times. but the danger of hard, non-gradual braking is that one can lose control over the bike even before the actual lock-up of the front wheel occurs.
I can just share my experience with changing master cylinders. before I had to use three or four fingers to make the bike stop in emergency situation, and now with the smaller MC, one finger is enough and there is much greater modulation. I did that change to Versys 1000, Vulcan S, Tiger 800, CRF 250, and both of my Royal Enfields. If people trust so much manufactures, why the aftermarket companies make so much money? OEM brakes, suspension, seats, and what not, are often produced in lower costs to save money. Well, the bigger vs smaller MC will not make difference in production costs, so it is beyond me (other than the safety measure or the fact that people naively assume that firm lever equals better brakes), why they do that.
the great thing about gs310 is that it is fitted with radial calliper and four pistons. this will no doubt improve its braking capability. sliding two piston callipers are much inferior.
