How many RPMs do you expect?
14k?
I personally am not aware of a 'thump-thump' that could scream past 10k anyway so I see no point in starting a brand new thread about it.
It's hardly a high compression 4-Cylinder screamer with a feather weight flywheel, aluminium forged pistons, titanium valves, ram air intake, huge radiator etc etc...
Duh!
Even KTM 690 Duke; the world's most powerful road-legal single-cylinder motorcycle hits the limiter at 9.5k.
Why we expect superbike like performance from a fuel efficient small displacement commuter motorcycle with a single cylinder engine; I'll never know!
Good Day!
