How to gear it

[Todd JacksonMember]

Guys,
Thanks for the help, so what I’ve picked up is the ratio equals rear sprocket / front sprocket.
ie 14/47 = 3.357
14/39 = 2.787

And if i’m correct the higher the ratio the more grunt/wheel stand capabilities but less top speed
The lower the ratio less grunt but more top speed (longer legs)

And a smaller front cog increases wear to the front cog. 2 fronts to a rear?

BUT, I thought I had to change both cogs and chain at the same time?
I thought I saw it straight but now I’m confused :blush:

I’m only new on the tools.

Yep.

Generally, yep.

And a smaller front cog increases wear to the front cog. 2 fronts to a rear? Yes, dependent on riding style and sprocket/chain quality.

BUT, I thought I had to change both cogs and chain at the same time?
In an ideal world yes. Practically, no. If you change your front sprocket before it gets too worn (teeth look like a wave shape) you avoid damaging the chain enabling you to run another sprocket with the same chain and rear sprocket.

It’s okay, it’s very complex. Some people make it that way anyway….

Better than being a new tool

Just my opinion, I’m probably wrong as I don’t have 30 years experience.

Thank you for the response. Going off some of the earlier posts I thought we may have lost you.

Have a great day!

I made a special concession for you

Is a 12 tooth front considered too small?

What negative affects, aside from quicker wear, could be caused by the smaller front?

I ask, because I have just put 12/45 gearing on my DRZ400. It came with 14/45, which I found far too tall for the tight stuff I like to ride. 12/45 feels good, and I reckon 13/50 would be perfect.

Cheers,
Glenn

If I have this right in my head, what you have done is effectively put the equivelent to 6 teeth on the back. Which is 14/53 which is also equal to 13/50 if my sums are right.
No doubt someone will correct me if I am wrong.

Here have a look at this and try and make sense of it.
