Can someone who knows stuff about gearing explain to me the advantage of the 18/46 gearing over say 16/41 that has the same ratio?

I remember reading that when racing teams settle into the best ratios for the final drive they are more likely to change the gearing in the transmission. The only problem I see with going down to a 16 up front would be if the diameter is too small for the chain. But if it fits and doesn't bind, than you get a little weight savings. Then again, would smaller gears survive the power that this bike produces? Yes, there are a lot of questions.

The reason I ask is my old 98 model ZX-9R had a final drive ratio of 16/41, I m just wondering why they have gone with this gearing which, according to a drive ratio chart, delivers the exact same final drive ratio as 16/41, and was hoping someone could explain the benefits of it.

I am happy with the OE gearing and, for my intended use, have no need to change. I enjoy the explosive acceleration and can live with the amount or revs when cruising at hwy speeds.

I've got the h2 swing arm fitted and run a 44 rear sprocket 4th gear is my favourite gear 😁, the swing arm came with a 41 which I felt would b no good so I bought the 44 couldn't get a 46 at the time, anyway I've kept the 41 as when the flash available the 41 might b the one 🤷‍♂️
