GL1100 Engine2

Those of you who regularly ride in the rain will know just how poor brakes with solid discs are when wet.


THEY ARE TERRIFYING! A Honda GL1000 weighing 600lbs of bike, plus rider(s), just wants to keep on going!


The biggest improvement to wet weather braking is the drilling of the rotors or discs.


You really cannot believe the difference it makes!


Below are the standard patterns I offer. You can specify what diameter of hole you want from a choice of 4, 5, 6 or 7mm in any order. Same pattern for front and rear. I can also do special one-offs to a supplied picture or pattern at additional cost.

"If anyone is looking at making improvements to their Gold Wing the front brakes are absolutely in the top 5 things I would recommend.

Over the years I had been caught in too many heavy rain storms and not had any brakes with the stock system.

When riding in really heavy rain, the stock system can not shed water from the rotors fast enough to provide enough satisfactory braking even for a mini-bike!

Drilled rotors fix that  and combined with the Stainless Steel Lines provide a difference in feedback and feel and authority that is really just amazing.

Operating on a budget as most of us are I would spend the money on the M/C and SS lines then try and find someone local to drill the stock rotors. Strip and rebuild your calipers with all new rubber and build the system up.

Then do a really thorough bleed and the difference may save your life !! "
