The stock or replacement lines will bolt right on to the gsxr calipers.

Finally finished my front brake mods. 01 RC51 MC (19mm), already had SS lines, and F4i calipers (34/32mm). Hand milled the calipers to clear the lower mount and epoxy coated the cuts. Everything went together well though cleaning the wheel (with kerosene) and then the rotors with red scotchbrite pads (first with detergent and a bit of ammonia and then with 91% isopropal alcohol) took the longer. Lever feel seemed a lot better than the RC51 MC and OEM VTR calipers, as the F41 calipers properly match the 19mm MC. Trouble is I don't know when I can road test everything. It will be interesting between my new bar mod (about 1.25" higher and 1.5" rearward than Helibars), my reshaping of a custom 1.5" taller Sargent saddle (this is the 3rd time I've wacked at it over the years) and the fully moded front brakes. The new bars and saddle are designed to mate with 1.25" lower pilot pegs for a true sport touring stance.

Still waiting for the Superbrace from the group buy!

 

I did the same upgrade early fall '07 but used the '01 RC51 calipers instead of the F4i and the slowing/stopping power for this combination on the SH is tremendous. I am pushing 290# with gear, not fat just a big guy, and the first ride was impressive.

Regarding the SB, you and Hotbrakes ordered the same black anodized brace and for some reason SB is having a hell of a time gettting these made. MFI spoke with SB about this matter and could not get a conclusive answer from SB. Hotbrakes cancelled his order. If you want to call MFI, here is there # 1-866-583-9600, anyone in Parts can assist you.

Good luck.

 

Thanks man but I've been in recent contact. I DID NOT order a Black one, just the regular old Clear finish. Chris promised me something and I'm waiting a bit more to see if he comes through...

The F4i are identical to the 01 RC except they are Black. Hopefully it will be a nice change and hide brake dust, or the old Goldies are going back on my fast 98. I try things progessively, first the 01 RC MC, which increased pull and decreased sensitivity so the jury is still out until I can FINALLY ride! And its only the end of February.

 

woooo woooo my head is spinning. brake overload! Thanks for all the great info. Im in need of this mod and now just need to sift thru all the options. Id like to reuse my aftermarket levers and my ss lines. Any of these mc's fit this with a remote reservoir?

 

Certain levers fit certain MC, check the thread(s), its been covered. Most lines will fit but the angle of the dangle on the cal varies. Just remember not all cals are true bolt on, like the RC51 and F4i which need a bit of milling to clear the OE VTR lower cal mount bracket.

 

Thanks. Anyone have pics of F4i or RC Caliper after being trimmed to fit? There are alot of options it looks like and may come down to availablitly. superbling pointed me to an F4i setup I may look into.

 

Thanks guy for all the awesome advice XLSR-VRT1 I am in your shoes to much goodness to choose! I will be posting up some pics of my upcoming mod soon enough before my track day here in about two weeks. Hopefully all will go well!!

Hey XLSR My bro lives in ballard and rides a VFR you got alot of guys you ride with up there?

 

I don't have photo's of the trimmed area on the calipers, I do have mounted shots though. I included stock caliper photo's for size reference. The F4i's/RC51 Calipers are a lot more potent that they look!

 

Not my milled pics cuz I also forgot to shoot my black F4i calis but these gold RC51 are milled the same. 00 & 01 RC51 calis are the same as all the F4i but after the reduced the RC51 pistons a bit. Note very carfully where the cut is and how deep, its not centered and they are opposite hand left-right. Do not cut too deep and touch up with 2-part epoxy paint the bare aluminum. The installed pic is my work.

 

I installed the six pot GSXR calipers and have an 07 GSXR1000 Radial Front Master cylinder and lever assy. on the way from Ebay.

I am excited about trying the Radial Master cylinder with its improved plunger location.

I most likely will need to buy new SS lines and sell my existing SS lines as the Radial MC has different line connection angle over the older traditional MC's
