ozn3 Posted June 21, 2020 Share Posted June 21, 2020 Has anyone done this on the GT? If so, how's your experience? I believe, you'd need four 11mm spacers for the calipers and longer bolts. Would anyone know the exact bolt specification needed? Planning to use sintered brake pads with bigger front rotors for better braking power.

Supporting Member roadrash83 Posted June 21, 2020 Supporting Member Share Posted June 21, 2020 @ozn3 I had some spacers made up and changed out the rotors and changed over to the Spiegler brake lines. I feel the biggest improvement was the line change. The bolts that I used are M10x1.25x90mm. 1 1 He who dies with the most toys wins. Link to comment Share on other sites More sharing options...
Supporting Member texscottyd Posted June 21, 2020 Supporting Member Share Posted June 21, 2020 There was a really detailed thread about this 320mm brake conversion topic, but it seems to have been removed. It had part numbers for rotors, spacer specs, install tips, lots of personal experiences, etc... I’m thinking it was in the Forks By Matt forum area, and was removed since he’s no longer a supporting vendor. @Cruizin - Is it possible to find that thread and move it into one of the active technical forums? 2 Link to comment Share on other sites More sharing options...

Yeah, I saw that and was looking for it too. Sorry if I had to post this topic again 😅 1 Link to comment Share on other sites More sharing options...

ozn3 Posted June 30, 2020 Author Share Posted June 30, 2020 Does anyone know the exact specs/dimensions of the spacers? Will just have them made in a machine shop. Link to comment Share on other sites More sharing options...
BBB Posted June 30, 2020 Share Posted June 30, 2020 IIRC they gave an 11mm spacing. The diameter is the same as the calliper mount. Mine have a step/recess at each end so they insert in without wobbling, but I’m sure that’s not essential. 1 Red 2015 Tracer, UK spec (well, it was until I started messing with it...)

Would anyone be able to verify these dimensions? please forgive my sketch haha actual photo of spacers for reference which I got off the MT09 forum. 1 Link to comment Share on other sites More sharing options...
Supporting Member roadrash83 Posted June 30, 2020 Supporting Member Share Posted June 30, 2020 @ozn3 I have one more set of 11mm spacers left but the shipping to the Philippines would be cost prohibited.

All these check out, except OD. Mine measures 25mm, but it is powder coated. The OD is a little larger than the mated caliper side, but just right on the fork side. If you already have these or can source them easily... I think 24mm will work fine.

SuperMax Posted June 30, 2021 Share Posted June 30, 2021 Has anyone installed 310mm rotors so far, or only 320mm ones? Asking as I do have a pair of 310mm YZF-R1 rotors (that were used in the 2007-2014 models), but since 2015 the R1 has 320mm ones. My concern is that I have the 11mm spacers and the 10mm difference will actually require different spacers and probably M10x1.25x80mm bolts, instead of the M10x1.25x90mm bolts used with the 11mm spacers and 320mm rotors.

Premium Member 2and3cylinders Posted June 30, 2021 Premium Member Share Posted June 30, 2021 I have I thought the 14 rotors which are 3 twenties and fit fine I don't know about the 3 tens though Link to comment Share on other sites More sharing options...

Are you sure they are 310mm? from an R1? I dont think R1's ever came with anything other than 320mm rotors. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
SuperMax Posted July 1, 2021 Share Posted July 1, 2021 (edited) Absolutely sure they are 310mm! All R1' from 2007 to 2014 came with 310mm discs. It's only the R1's from 2004-2006 amd 2015+ came with 320mm. Funny thing is that some rotor manufacturers specify the 320mm rotors for all R1 generations. The only downside would be having the pads not touching the 310mm rotors for about 5mm on the outer edge of it. PS: curious if the 320mm rotors made it a pain removing/installing the calipers, as the distance to the rim would be leaving very littile room for it Edited July 1, 2021 by SuperMax Typo 1 1 Link to comment Share on other sites More sharing options...
