2003 RM250: Need help identifying rear spring rate.

I have a 2003 RM250, the bike has a red shock spring installed. The factory suzuki manual only gives four options; green(4.6kg), pink(4.8kg), black(5.0kg) and blue(5.2kg).

I called the stealer, and they had no clue. Do you think "red" got translated as "pink" in the manual?

Thanks, Steve.
