Just one tooth

Recommended Posts

Talking gearing is like asking "what's the best tire?".

Even so let's go there into the quagmire. I changed my gearing - I went from 16/43 to 16/44. Ya, I gave that torque-kee wheelie machine a little more jazz (but not for wheelies, just the opposite).

For those who don't know I yanked the stock suspension out of my bike and slipped in Ohlins NIX 22 and STX 46. That move transformed everything, it's not the same class of machine that rolled out of the showroom. The bike is PLANTED, confident, capable of things most stock bikes can't deliver. It's another world, but that's a different story.

So I slipped on a 44 tooth rear sprocket. One more tooth. Here's what I ride now.

A bike where 6th gear is not "way out there", no it's been invited back to the party the rest of the transmission is having. And that transmission wall-flower 4th gear - wow it's suddenly discovered all kinds of things it can do.

That one tooth pulled the whole transmission together in a way that amazes me - I mean that totally. I never imagined the payoff I got. One tooth has made everything disjointed about that tranny come together like a great rock n roll song.

One caution, you know how the stock suspension when you launch at an intersection, those few ripples in the transition cause the stock forks to pogo cycle then loft the front wheel and you cooly carry the front wheel across the intersection. Ask yourself, is that a suspension operating outside its capabilities?

You all have an amazing motorcycle, so capable but held back by one item Yamaha neglected intentionally, they threw 1990 forks in an 2020+ machine.

You can fix that, then add a tooth, and have a planted racebike that will probably be the best handling machine ever owned. And you don't need Ohlins. I think emulators are about $500.

I wish that for you all, because it's like getting another new motorcycle

But adding a tooth increases your acceleration or speed? Can you explain it better to us

With just one tooth on rear sprocket, the seat of your pants won't notice the very slight increase in acceleration. What it will notice is a more uniform cooperative transmission

so we can talk about being smoothness overall?

The act of physically shifting, the effort required remains the same. Be assertive in all your actions just as before.

What changes is the whole dynamic of how well matched each gear ratio is to another, and the rpm where shifting is taking place.

And gears you would normally shift right thru and on to the next higher, suddenly you find them very useful. I rarely had any use for 4th gear, and now is a powerful useful gear for cruising in certain speed zones.

And 6th, was always "out there" from 5th, quite a jump, an overdrive, is now a ratio close enough to 5th it's as natural as shifting from 2nd to third. No longer a shift into overdrive, it's tight and close. There is no overdrive.

There's just a tight, coherent tranny. Yamaha should have released this bike with a 44 tooth.

Definitely the setup for aggressive street riders, without taking a thing away from my long cruises on wide open country roads. 6th still has plenty of legs so the motor remains relaxed even when your cruising at a pretty good clip.

It just works better everywhere
