Another way to extend your range is to use the 33 oz MSR fuel bottle

They can be carried in your backpack or fastened to the bike

Theyíre available at most sporting goods stores

I bought mine through Amazon

And thereís a handy Tractor Operatorís manual canister available from Agri Supply

The 22 oz MSR bottles will fit perfectly in the canisters with a little room for some padding.

I put the MSR bottle in a thick sock and it still fits in the canister.

The cap screws on tightly for security.

It has tabs to mount it on the bike.


The KLX 250 is geared a little tall from the factory and benefits greatly by changing the 14 tooth countershaft sprocket to a 13 tooth sprocket.

I good place to get a quality AFAM 13 tooth (part number 24502-13) sprocket is from Cogent Dynamics.

Call Todd, Joyce or Rick at Cogent (828)-628-9025 and ask for the 13 tooth sprocket for your KLX250S.


Cogent also has fork springs and shock springs available for the KLX250S

Stop that front end dive with a pair of .44 kg/mm rated Cogent springs

The rear shock also benefits from the Cogent 6.1 kg/mm rated shock spring
