All PBT keys have the same chalky feel. Some love, some hate and others, like me, can see the difference but don't make a big deal out of it. If the PBT keycaps from the Race are the same from my KBT Oni, the pad printing also helps for a rougher feel, but I honestly don't even usually notice it. PBT is a lot harder than ABS and one of the reasons people prefer it over ABS is because they don't wear off easily. Model M's have PBT keycaps and I have never seen a worn out one, so you might get tired if you decide to wait for them to wear.
Get some DoubleShot (or even lasered, if you don't care) ABS keycaps to replace them if you hate it all that much. ABS is very common to find and I'm sure you can find pink keys, even if it's through the Custom WASD keyset maker. No big deal.
EDIT: just realized that since you mentioned it having pink keys, I believe it's the limited White LED Race edition? If so, I believe these have ABS caps. Shouldn't feel as chalky as PBT then. Maybe someone can clarify if it has something to do with the dying process Vortex chose, or if it's just the pad printing feel.
