For those of you who have seen some of my pestering questions, you know how I have been interested in making the swap. I really never like the m4.32 calipers - either for aesthetics or performance. The best bang for your buck is an RCS 19 and pad change, but I went a step further. Brembo M50 calipers Brembo Z04 pads Brembo RCS17 master Spiegler custom brake lines Ducabike righthand switches V4Evo titanium safety wire drilled caliper bolts (not installed yet) Cost: $525 brand new M50 calipers $255 rcs17 $175 Z04 pads $120 custom lines, banjo bolts plus motul rbf600 brake fluid $260 right hand switches (arguably optional) $50 titanium caliper bolts with safety wire (optional and still shipping) -$545 sold stock calipers, master and brake lines I would say I am $840 into this project, but if you wanted to reuse the stock switches and caliper bolts it would be around ~$500. Hell, if you went with the cheaper Brembo pads you would be closer to $400 flat. Install: Not that big of a pain in the ass, truthfully. I am a 4 or 5 out of 10 in mechanic skills at best. I have never done a brake job in my life, always paid to have it done for my track bikes. All you really have to do is take the seat and fairings off (just a few bolts and they pull off easily with velcro). Then you need to disconnect the gas tank, unscrew two bolts and lift it off. From there you need to snip off the zip ties for all the wiring on the airbox, loosen a ring clamp on the front and back of the box and lift it up. I actually never fully took the box off, which made life hard but I was trying to remove as little as possible. From there you have access to the abs box and I used clear tubing to measure the lines (measured about 90 times). Drain the fluid, remove the old line, run the new line, bleed the brakes and voila. Really not that bad, honestly. A few things to note - I tried to reuse the stock master cylinder bracket and snapped it in half contorting it. I ended up getting 1/8" thick aluminum, cut it down, drilled a few holes through it and bent it with a vise. I will look to make something prettier in the future. It is mounted to the handguard via the top screw. Also, not having a service manual makes everything way harder. That was really the hardest part - I ended up looking at this parts guide frequently to reverse engineer it. 2020 Ducati Hypermotard 950 SP OEM Parts Diagram Ducati Omaha You can totally reuse the stock switches but you have to reorient it to the left side of the master vs the right, and you would have to shave down the little nub that goes into the bar. Financially the wise move, but I like the ducabike look The abs to front caliper line is 47 inches, and the buddy line from caliper to caliper is 17.5 inches. I think it came out pretty perfect. I 10000000% recommend using a compressor assisted bleeder, because even with that it took a long while to get it right. Verdict? Pretty dang awesome. Stops like a monster and totally looks the part. I am very happy with my mod. Hope this helps anyone else who decides to follow my path.
You should be very happy with that! It’s something I quite fancy doing at some point. Just out of curiosity is the tank fuel hose fitting just a squeeze and pull? I’ve removed my tank a few times to change the exhaust and airbox etc but always just left it connected and put it on a bench next to the bike.
Thanks! That sucker actually took me a bit to figure out. You twist it partially counter clockwise and then it pops right out.
How do you like the M50 performance? I never like the M4 either. I do plan to change to Stylema or .484 at some point. I switched the brake pads to Brembo SA pads but the improvement is fairly negligible.
I have been really impressed! Hard to tell if it is the master, pads or calipers, but something is stopping it way better than before
Great set up. I’m a big fan of the RCS masters. Pulls up very well. I have a set of Carbone Lorraine pads to try next season. I plan on tracking the hyper next season so it’ll get the full extreme test then.
@dynastyss Sorry to jump on your thread btw. Does give the audience a good illustration of both M50's and M4's fitted
Why did you need new brake lines? it seems the standard lines would work as the calipers mounts are on a 45 deg like the stock? RR
I should have took photos but the m4.32 calipers and m50 calipers have different line mounting angles. Stock would have needed a very stressed position and most likely failed pretty quickly
I thought if you flipped the lines the opposite way? I ahve a set of GPX calipers and to run new lines is a nightmare ? I want instant gratifiaction is all ... Lols RR
The stock lines didn't allow for the head to rotate like my aftermarket ones. That said I'm not familiar with the line mounting position of that caliper.
they are horizontal so I need 90 deg bends so saw this post and thought I could use a set of M50's as they are on the same 45 deg mounting boss and the stocxk lines would work? esp the left to right caliper line just bent the other way, but im sure this cant work as that would be way to easy... RR
Honestly can't hurt to try I guess but you'd be the only person I've seen do an m4.32 caliper swap and retain the stock lines. All the guys across the numerous bikes these calipers came on had to go aftermarket as well. I wish you luck though
I use 07BB38SA. Brembo only recommends either SA or LA for performance upgrade anyway. SA feels more gritty. I think it might eat the brake disc much faster. I might upgrade it to 484. Cafe racer calipers later.
