They are incorrect. YTX-14BS is the correct size , only 9BS is used in the GV Aquila 125 due to their smaller battery.
“Some” GT125R bikes in the past came in 7BS (scooter) in the UK as that’s the cheapest battery a dealer can fit to save his money and push the bike out the door!
Get YUASA in my opinion. Powerline and chinese makers are rubbish, not good for your charge system or avoid lithium at all costs (Hyosung doesnt support lithium)
If no YUASA , get VARTA (German) , i used it in the past with no complains and sometimes UniBatt but that’s only if i can’t get the prior 2.
Good luck!
