In general: smaller volume = higher compression = more pull but better fuel needed; larger volume = lower compression, the engine revs out more freely and tolerates pump fuel. If in doubt, take the standard.
Based on the VHM manufacturer charts.

Exchangeable combustion chamber (insert) for the VHM cylinder head AA33182. Chamber volume 27.50 cc. 🔴 The insert fits ONLY the VHM head AA33182 — it cannot be fitted into the OEM head. For the stock (OEM) piston. Quick to change — the insert simply sits in the head and seals with O-rings. The last characters of the part number are engraved on the insert, so you cannot mix them up. Fits: Beta RR 300 2T (2013–2024); Beta RR 300 2T Racing (2018–2023); Beta Xtrainer 300 2T (2019–2027); Beta Enduro RX 300 2T (2021–2022); Beta Cross RX 300 2T (2023–2025); Beta RR 300 2T X-PRO (2025–2027).
