In this one I’m basically starting a slightly ridiculous mission: can I upgrade my 2019 Kawasaki Z900RS enough that it’ll hang with (or even beat) a 2026 Z900RS—if and when that bike shows up? I’m not asking you lot to wrench for me, I just want your opinions. What would you change first, what’s a total waste of money, and what mods actually make a difference on the road—not just on a spec sheet or an internet argument. I talk through the idea, the plan, and the reality of chasing “new bike” performance with smart upgrades instead of just trading up. The big takeaway is that I want this to be a proper real-world comparison, not a bench-racing thing—so if you’ve got a 2026 (or you’re planning on getting one), I’m genuinely up for lining them up and testing them back-to-back. And yes, hit the like button if you enjoyed it—apparently it pleases the gods of YouTube, and I’m not here to anger the gods.
