A quick note to all those with R1 calipers. I fitted my brothers XJR-1300
master cylinder, lever assembly today. The results are amazing. The lever
travel is longer than the Max, but is identical to the XJR. The amount of
braking effort required is so small I feel like I'm riding an R1. It pulls that
big barge up like it weighs 1/2 of its real weight.
In fact I don't think I will ever use the rear brake again other than for the
final couple of mph for stopping to maintain balance, as you would approaching
a set of lights.
This setup brings Max up to the year 2000 in terms of braking technology. I
also have EBC-HH pads which definitely helps, but frankly the Max would now
stop as easily as big bro's XJR. But don't tell him I stole his master. I asked
our Yamaha dealer if there was a new one in stock yesterday. He told me there
was only one in Australia so I told him to order it in case the swap was a
success, believe me it is.
For you guys in Europe with R1 brake calipers, order the XJR master as well and
enjoy braking finally.
You guys in the U.S get the Europeans to get you some of those master
cylinders, it's worth the effort, especially when you compare the price of
those other aftermarket brakes. If you don't believe me that's also cool.
If anyone wants me to research the possibility of buying the master cylinders
here and shipping to you let me know. As a matter of fact you could all get
Charles to fill his suitcases with them if he is only staying a short time.
