"upgrading" calipers on 999R
I've thought about changing out my stock radial calipers a number of times on my 03 999R. I'll be the first to admit I like the looks of a monobloc set like the less expensive Brembo M4s and that is one reason for the upgrade. My stock radials are basically silver in color and the word "Brembo" are raised letters also silver in color, while the M4 Brembo name is recessed and painted red, I like that detail. The second need is the possibility of better braking performance, paying particular attention I like to trail brake so a brake that gives a softer feel on initial compression and then bites harder is what I'm most looking for. I know the master cylinder plays a role and also the pads, so I'm looking for some advice or recommendations to what kind of pads I should consider.
About nine years ago I changed out the brake and clutch masters to Brembo billet 19x18 brake and forged 16x18 clutch. They aren't the high end ones and I also installed Rizoma reservoirs. If the M4s/MCs are compatible, they should be, if not, I have no plans to change them out and will pass on the caliper upgrade if the clutch and brake masters aren't a good fit. Another consideration afterwards (I just changed the brake and clutch fluids) is to update the reservoirs with Rizomas that have the bigger fluid level windows.
A used pair of M4s is a good possibility if the condition and price are right. I'm pretty anal about the bike, so the looks of the M4s plays a big role when considering used.
1. Looking for better initial compression feel when trail braking.
2. Recommendation on pads, if I buy the calipers new, are the supplied pads optimum or is there something better?
