Welcome,
Has the bike sat for any length of time? You may have a partially clogged fuel injector. Is the air filter clean? Possible clogged exhaust. I'd focus my search on getting air/fuel into, and exhaust gases out of, the engine. You could have out of sync throttle bodies, but that doesn't have quite so drastic an impact on the bike in my experience.
Ignition issues typically span the whole rev range, but it may be worthwhile to change the plugs and wires, although I'd be surprised if that was necessary on such a young bike.
