Himalayan 450 vs Scrambler 400X for the odd track day, worth the swap?

Been eyeing the Scrambler 400X lately just for occasional track day fun, keep the 450 for touring and photography runs. Saw the spec sheet on BikeWale, Scrambler is about 11 kg lighter than our 450. On paper that should matter more on a tight track than the extra torque the 450 has.

Anyone actually ridden both back to back on a circuit, not just highway? Does the lighter weight actually show up when you're chucking it into corners, or is it marginal once you're already used to the 450's ergonomics. Thinking out loud here, not sold on either side yet.
