A stock CBR150R throttle body can be used, as many vendors are selling in the US and all over the world, but it’s really hard to get your tune right, certainly with the stock ECU installed.
With the Yuminashi 31mm throttle body, the stock MSX125/SF - Grom 125/SF ECU can be used because of the special installed Yuminashi sensor block!

The main reason for the Yuminashi R&D to start with an improvement on the 35mm, and also on this Yuminashi 31mm throttle body, was to solve the issue of tending to run very rich while running lower RPM's on a stock ECU and this with about any injector type.

It was very hard then to pick up the RPM's if you suddenly open full throttle. The formal generation 35mm throttle body was also tended then to run quiet lean in the higher RPM region where we want to see the opposite actually with a well balanced air fuel ratio engine, so the use of the newly developed sensor block is utmost recommended!...

The set includes the matching B-Type intake manifold set, CNC machined high grade aluminum spacer, injector housing, manifold insulator, adapter harness, and O-rings to fit the stock 125 head intake port!
