Could someone please explain gearing to me, I understand the concept, smaller gears = more torque, and bigger gears = more speed and less torque. But there are gears, five of them in the tranny, and the ratios change when you put on smaller and larger gears throughout the tranny range. So for more torque you put a smaller gear where? and more speed you put a larger gear where? and if you put a smaller one in the rear and larger on in the front, or vise versa, does it just counter act your change. If someone could clear that up for me that would be much appreciated, thank you

<< smaller gears = more torque, and bigger gears = more speed and less torque >>


Not exactly true.

It basically boils down to the equation for gear ratios: number of teeth on the driven gear divided by the number of teeth on the driving gear. The countershaft sprocket(front) is the driving gear. The axle sprocket is the driven gear. Ex.: 39/15 = 2.60 ratio. A bigger number in the numerator(larger axle gear) will drive the ratio up yielding more low end torque/quicker to rev out/lower top end speed. Equally, a smaller number for denominator(smaller front sprocket) will yield the same results.

Changing two teeth on the front sprocket is <u>about</u> equal to changing 5 teeth on the rear(or 1 front to 2-1/2 rear)- depending on the range you are running. That would be a good approximation for you to use. That should lead you to understand that the front sprocket should be changed to make a more major difference in gearing and the rear would be used to fine tune your gearing.

It would be close to the same if you went down one in the front and up 3 in the rear.

Hope that makes sense.

 

yes it does, thank you

As far as sprockets go, a smaller front, bigger rear, and smaller rear tires will give you better acceleration and less top end. Changes to the front sprocket will make the biggest difference, the rear sprocket will be noticeable but not like the front sprocket, and the rear tire size will make a big difference too but not as much as either of the sprockets.

Yeah, and if you reverse your front wheels......it's bad for the quad! [img]i/expressions/face-icon-small-shocked.gif[/img] [img]i/expressions/face-icon-small-happy.gif[/img]

Sorry buddy, just to do it!

 

Trout,

Being from Colorado, you must have a Mountain Bike.

Go ride it, and you will get a better understanding on (front/rear) sprockets and how they affect each other.[img]i/expressions/face-icon-small-smile.gif[/img]

I certainly wish my DS had 21 different speeds![img]i/expressions/face-icon-small-confused.gif[/img]


Biggerisbetter.

 

Here let me throw some more confusion into this equation. You can overgear or undergear a quad.[img]i/expressions/face-icon-small-shocked.gif[/img]
