Drive ratio

Recommended Posts

Dear all,

I'm riding with 52/13 sprocket ratio.

It gives me nice torque on the bottom low gear, as mostly I ride hard enduro.

This ratio is 4 to 1, my question is, if I change the setting to 48/12, which gives the same 4 to 1 ratio, will the bike behave the same way? What is the difference between settings achieving the same ratio but with different T numbers on the front sprocket?

And what ratio would you recommend for hard enduro ride, slow technical terrain?

I ride ktm 400 exc 2011.

Thanks in advance,

Adi

Since the overall gearing is the same, the engine/bike will respond in the same way.  If at all possible I would avoid using the very small 12T sprocket. 13/52 is plenty low enough for any normal riding condition.

The same ratio will give you the same performance, but the tighter turn of a 12T over a 13T might wear out your chain faster, as well as your front chain guide/block (on top of the swing arm).

The 12T lowers the turn radius of the chain and puts more stress on the pivots.  Don't know if that results in faster wear, but may be worth considering.  My last three bikes have all been 13/52.
