Final Thoughts

Like previous video (higher capacity modern classics) I tried my best to be impartial but for me personally, the top smaller capacity modern classic has to be the Honda CB650R and Kawaaki Z650RS
So there you have it—the ten smaller capacity modern classic motorcycles that are defining 2026.
