In terms of raw performance, these two are evenly matched. The 500SR VOOM and ZX-4RR produce nearly identical power figures, meaning the real-world difference will come down to gearing and torque delivery rather than peak horsepower. When it comes to agility, the ZX-4RR has a clear advantage. Weighing in 5kg less than the 500SR VOOM, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: It's a close call. Choose the 500sr-voom if you prefer its specific styling and ergonomics, or the zx4r if you want the alternative brand character.
