So you don't think steel with hold up better to sand than aluminum?

I have ridden dirt bikes and four wheelers in sand most of my life and
have not seen the rapid wear I am seeing on my 18 month old bike.

 

Have you done a similar mileage off road, that you do on a Harley, your money, your choice.

 

super helpful...thanks for continuing the discussion in a meaningful way

 

I only ride my Harley on dirt 10 miles out and 10 back to my house the rest
of the time is spent on asphalt.My dirt bikes and wheelers lived in the sand.

I seen a thread on another forum talking about which is better chain or belt
and someone mentioned sand being harder on belt drive pulleys,so I walked
out to the shed to inspect mine and was horrified at the amount of wear I
have already.

 

It appears by your tone, you've already decided a chain is better.

 

literally laughing.... pot meet kettle

my tone means I don't think your answers are addressing anyone's questions.

I honestly want to know why sport bikes never use belts. I understand why they would be better for traditional cruiser applications, and would think they would be for sport bikes too, but clearly they are not.

It think its obvious why chains are better for dirt bikes and the like.

 

Someone posted this earlier, did ya see it?

Ok, add in gaskets, bolts, beer, time, etc.

 

I didn't... thanks for the link...

So belts are maintenance free and last forever(ish), but rob a bit of power
Chains are efficient, provide more wheel clearance, but are dirty and wear out quicker in road applications.

That would explain why dirt and crotch rockets use chain and cruisers use belts..

 

So, how does a belt "rob power"?
