New guy here. Great info on the this forum. I'm looking to upgrade the front brakes on my '99 SHawk. Will the front brake calipers and MC from a 2003, 2004 CBR 600rr work on the SHawk? If not what year calipers and MC do I need?
Thanks

but since its a new year, I feel generous. Remember, to gain the advantages of the larger caliper pistons the master cylinder piston diameter & stroke must be sized to the caliper piston sizes. You can go for less lever movement and higher effort and "power" but reduced "feel", or a higher mc to caliper ratio and more feel but less braking strength.

so see below as posted long ago by someone else...

The F4, F4i, 600RR, RC51, 929RR, 954RR calipers are all externally identical, and they need slight grinding to clear the mounting bracket on the VTR fork leg. Other than that, they bolt on and work quite well. The caliper piston and master cylinder sizes vary from model to model and year to year. Here is a little chart I stole from another post with all the data.

2003-2004 CBR600RR mc 11/16” (17.4625 mm)
caliper pistons 32mm/30mm

2000-2001 CBR929RR mc 19mm
caliper pistons 34mm/30mm

2002-2003 CBR954RR mc 11/16” (17.4625 mm)
caliper pistons 32mm/30mm

2000-2001 RC51 mc 19mm
caliper pistons 34mm/32mm

2002-present RC51 mc 11/16” (17.4625 mm)
caliper pistons 32mm/30mm

1999-Present CBR600F4(i) mc 5/8” (15.87mm)
caliper pistons 34mm/32mm

Stock VTR Master Cylinder 14mm
caliper pistons 30mm/27mm

edit: You can see from this list why the RC51 and F4i calipers are the preferred ones. As for the Master Cyl you choose to match it: Larger MC = less lever movement and faster, while smaller MC = more lever movement and strength. (from increased leverage)

I have CBR954 calipers and master what seems the same you ask, and it works great, really big impovement in feel on lever and stopping power. Pads are Ferodo STAC.

Let me know if you want to go that route, I have a spare set of SP-2 calipers (same as 954 and pre-USD 600RR units; 32/30mm pistons) I can let go for a good price.

cheers

I have exactly what you are asking about on my bike. '03 600rr front brake system. I think I used my stock lines though. I don't remember if that was out of neccesity or just because they fit a little better. Get some braided ones if they're in your budget. Oh and you'll have to do a little grinding on either the calipers or the mounting points on the fork leg. I did it on the fork. It's no big deal.

Thanks Guys, for all your input. I apologize, I should have done a search first (I did today). I bought a set of VTR Galfer SS lines and rotors to go with the brake setup. Calipers, MC, and pads should do it. Any suggestions on pads? Vesrah pad seem well liked on the forum.

If you use a 954rr MC will the will the VTR front brake lever work?

Nope... 900RR and VTR levers are interchangeable, 954 and VTR are not...

Thanks Guys, I ordered a set of Pazzo levers. VTR lever for the clutch side, RC51 lever for the brake.
