Q. Is Burgman Street or Access 125 better for a female beginner rider, 5.2 ft tall?

Yes you can, but you'll have to tilt the Scooty almost at every moment on any side, due to short height, My sister is 5'1 and she is handling Burgman good, I'll not say excellent, but as we both loved the styling of Burgman, she compromised on ultimate comfort, and chose Burgman over TVS Jupiter, Access 125 was never our option.

Due to big seat and long footboard, Burgman in very comfortable than access 125 however for short height people it can be little disadvantage as feet find it difficult to touch ground

TVS jupiter will be a good option for short height compared to burgman 125
