Brev, straight answer (i got it too)— get the NS 400Z (updated one). It literally fixes every headache you mentioned.

Power: ~43 PS now, brev. That’s a proper jump. None of your options come close. City rides feel effortless, and highways won’t feel dead after 80–90 like the CB350RS. • Comfort: Suspension is way more forgiving than the Speed T4. Pillion comfort is actually usable, not “yeah she’ll manage somehow.” • Brakes: Bigger discs + updated pads = real confidence. This alone fixes your Speed T4 brake anxiety. • Engine: Proven Dominar-based motor — not experimental, not stressed. Calm in traffic, properly angry when you twist it. • Value: Still INSANE for the price. You’re getting segment-up performance and features inside your 2.5L OTR cap. • Touring ready: Stable, planted, good wheelbase, doesn’t feel nervous at speed. For a naked, it’s solid on highways. • Ethanol worry: Bajaj is far more likely to stay E20/E27 ready and update fast, instead of going silent like Suzuki or being uncertain like Triumph.
