Only just saw this
Have had tps issue on car recently and sounds similar
Throttle responds to point the no more
This was resistance style tps
This type superseded by magnetic types then by alternative approaches altogether
More pedal does nothing as engine management doesn’t get signal past certain position putting upper limit on fuel flow and power
Actual physical throttle wider than indicated and may decrease output as actual charge leans out
Would indicate tps replacement
With these sorts of things diagnosis can be the most problematical thing and mechanic can be good value money and time wise though it can be frustrating in hindsight how obvious it looks and $$ disproportionate
Basically if bike not worked on before would hope parts like this last the life of bike
Second best is it’s a common issue common symptoms and common fix
