1 down 5 up
« on: 09 April 2015, 08:30:29 am »
So why is that then, I know some (i think ) are 1 up 5 down, but why are the gears not all up or all down, is it some sort of throwback from the early engines that has for no reason just carried on to today

I would say it's so you can be sure of getting first first time every time.  Let's face it once we're past 2nd it's often hard to know what gear we are in, so kicking down to first means we know where it is.

There is a neutral position for the selector drum between every adjacent gear (obviously one gear has to disengage before the next engages). They can make it available by putting a detent at a halfway position, thus a full movement of the gear lever will go past the neutral and a gentle nudge will let it settle at the mid position.
You could have a drum designed for a halfway detent below first, but the danger is that you'd change down for a tight bend having misjudged which gear you're in and get neutral rather than first.

It would still be easy to get 1st wouldnt it as it would just be all the way to the top or bottom

Let's say you're hooning it - very tight corner, down to first. And either double tap, or shift twice. Suddenly, you're freewheeling round the corner. Not good. Similarly, if you're on the motorway, and reach for "7th". and you find yourself in neutral? Again, no good.

And the reason to put it between 1st and 2nd is that you almost pull away in first, and nearly always stop in either 2nd or 1st. It's a convenient place for it to be.

Kawasaki's H2 triples were 1 up, 4 down. Horrible gearboxes, but no idea if that had anything to do with it. I didn't really notice any problems I'd associate with the gear pattern for sure.

No you wouldnt as neutral would be next to 1st which is at the other end, going for 7th would be just like it is now-- a dead end

There is no corner in the world that I would need to go from hooning to 1st, maybe a 2nd but not 1st

Just responding to the "what if neutral was at the top of the box" question.

Bigralphie is right, race gearboxes are 1 up, 5 (or however many) down. This is to make it easier to change up a gear coming out of corners. (You just tap your foot, rather than trying to get it under the shifter)

Well no - 1st IS currently at the bottom?

10mph would still be 2nd, there's just too much engine braking in 1st - talking FZS 600 here.

Nope because neutral would be below 1st  ;) :D

On particularly fast hoons, coming up to very tight hairpins, I've used 1st to get round the corner, then 2nd to power out.

That was on a 33hp Fazer though, I'm used to playing the gearbox like a piano, and keeping the revs high to milk out every single pony possible.

Perhaps the question is "where else would you put neutral in a bike gearbox,,as written,not the bottom or you would never find the creep gear.

Get one of these beauties if you can't handle the gears, it's automatic, pretty rubbish for keeping revs up when doing twisty roads (I know as I've used one) but good for touring where gear changes are less.
