front or rear

Back in Feb, I walked into a Yamaha showroom looking for parts for my bike and walked out a few hours later with a 15 VMAX. I just loved the look of this bike and couldn't resist the impulse! But now that I've blown my budget for the year I think I am going to have to do some of the work myself...

In between two completely independent brakes & modern ABS systems, some bikes have a system that distributes braking on a purely hydraulic basis between front & rear, say 75front/25rear. Would anyone here know if such a system is retrofittable to Mr Max?:ummm:

What is the stock front and rear recommended tire pressures?
