My Brembo front and rear caliper modification

Today arrived the goodies allowing me to fit front and rear Brembo calipers on my Duke 390 .
I was able to buy brand-new 100mm front brake caliper , rear caliper and the Brembo MC to go with it . As I have already upgraded my front brake MC to a 17mm Frando with the matching hydraulic clutch MC / slave , I will not need the Brembo MC which is a " plug and play for the 390 as all parts were originally for a Duke 690 .
I will offer the MC up for sale on the forum .

The rear caliper is a straight swap from our stock rear caliper and I managed to fit it in just under an hour .

On Thursday I will take my bike to the specialized center that already fitted my Andreani fork cartridges where they will machine an adapter in CNC to fit the Brembo 100mm caliper onto the 80mm spaced fork ends .

Congratulations, Yves! Another ground-breaking push forward! You are really catching a serious case of Pioneer-itis!

To be honest, I have been thinking about something similar. However, my current front brake setup works so well at the moment that I wonder how much benefit there would be from fitting a bigger Brembo caliper. I think it could be easily done using an adapter plate, as you are planning. My rear brake is so inconsequential and activates the ABS so quickly that I think, Why bother to upgrade it? But you will undoubtedly have a superb braking setup! Very, very, nice. I look forward to photos and ride report.

I have some other projects in mind....

Cheers, Will

Hard for me to argue that your current front brake setup is not great .. as you know I have the exact same setup at the moment : Having said that ; would you be interested in having the Radial Roadlok with machined to measure CNC spacers and the actual lock adapted to your setup at an unbeatable price ; Let me know . Yes , I will have to sell mine once I have the 100 mm Brembo caliper fitted I will need to buy the Duke 690 Radial RoadLok version to be able to fit it on that caliper .. another 300 USD down the drain !!

Indeed the stock caliper is 80 mm with M8 for the bolts where the Brembo caliper is 100mm with M10 for bolts . So they will machine a CNC adapter piece where the top fixture will go direct onto the fork stem by using a M8 to M10 bushing within the caliper bolt holes and bottom part will be countersunk to allow a shorter M8 with 1,00 mm thread to attach the adapter part onto the fork stem . Pull M10 x 1,25 mm thread directly on the lower part of the adapter to bolt the caliper onto . There is roughly 1,6 mm of adapter thickness , but of course this will only be possible when you fit a 320mm rotor .
Cost ? ... I will know exactly when all that is done . Guess once we have found the right setup it will be easier and cheaper to reproduce these adapters would there be more people interested .

yeah.. i done something similar.. i use a 320mm disck of a ducati monster, a 6 piston r1 caliper and made my own bracket adaptor.. trying to find a M8 in any size in titanium or anything else for that matter was a nightmare.. so i just drilled out the two holes on the for and tapped them out to M10x1.25mm which much more common.. a lot of work tho.. but the girl now stops with a 100kg+ guy sitting on it.. hehe

Same here , I couldn't source a M8 x 1,00 mm thread long enough to fit my 320 mm disk with stock caliper and Radial Roadlok . No way was I going to drill into my fork ends : Just needed to cut off M8 x 120mm with 1,25 mm thread and pulled 1,00 mm thread on them .
