MS will also change to titanium pistons. Since I always use only slick tires on the circuit, I will listen to your advice and use it because it is a course that requires extreme brake clamping. Because RR is expensive to use on frequent cleaning and public roads. Thank you very much for the...

It was the answer I really wanted and wanted to know. Thank you very much sir! I will use it for both competitions and public roads, but if I use it only for the race, is the GP4 RR the right answer then? If it's going to be used on general roads, MS is the answer, right?

Big caliper pistons aren't good! I thought that if the piston was small, the braking force would be weak. Because the master cylinder also has to use 17 pie. There was a lot of discussion because of this. Lastly, what do you think is the big difference between a 2pc caliper and a monoblock?

Thank you for the really good advice. But according to my common sense, isn't the bigger the Piston Pi the better the braking? For RX, it is 32 Pi. Stylema or ms is 30 pie, but is the smaller 30 piston pie better for braking?

Sorry for posting in Korean. If so, don't you adjust the presence or absence of 330mm, 320mm disc size according to the normal piston pie?? Would there be any difference in braking even with 330mm?

안녕하세요. gp4 ms 구매를 준비하고 있습니다. 다만 ms 피스톤이 30파이라서 330mm 디스크 사이즈로 가는게 맞는지 궁금합니다. 제 개인적인 생각으로는 320mm를 쓰는게 맞나요? 피스톤이 30파이라서 마스터실린더도 17rcs 코르사를 쓸 예정입니다. 현재 hypermotard gp4 rx+19rcs corsa를 사용하고 있습니다.
