That's definitely on the heavier side. What are the specs on your body and strength?
Be careful with those aggressive sweeps, especially on asphalt. You can lose the front tire or get a speed wobble if you hit uneven surface.
It makes people nervous being that aggressive, so kind of understandable if you're constantly doing it.

The lighter bikes are definitely more nimble though, and turn in easier. Not really a strength issue I would say though, only at low speed like you said.

Just interrupt the ground wire for one of the main relay coils. Either the ECU or ignition switch or something.
