Polarity location is determined by the letters H or HL.
Yuasa has 2 heavy duty batteries for the Rocket Roadster which uses the HL version. If you need the reversed terminals, get a Yuasa battery GYZ20H, good for 320 CCA and reversed terminals or the YTX20H, good for 310 CCA with reversed terminals. The original only puts out 270CCA. (PS, I'm not sure if these will fit the new Rocket 3)
