In terms of raw performance, these two are evenly matched. The R18B and R18 Roctane 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 R18 Roctane has a clear advantage. Weighing in 24kg less than the R18B, 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 r18 if you prefer its specific styling and ergonomics, or the r18 if you want the alternative brand character.
