I would agree with Sonreir, when you compare the stock disk brake setup with the stock, dual leading edge drums brakes. In fact, I'd say the drums might even be better.
However, I put stainless braided brake lines on my 360, and it improved the disk brake tremendously. I can actually lock the wheel if I want to (don't want to, but there was no danger of that with the stock hoses and setup. In fact, the stock setup with the disk might even be called Honda's first attempt at anti-lock brakes.. ;D ).
The feel and application pressure really improved.
I bought the lines from Slingshot Cycles, they did a very nice job.
