I have a 2006 KLX-250s. I am looking to replace the chain and change out the front and rear sprockets for better torque and hill climbing power.I would like to here what other people have tried and werearesome good places toget parts.

 

One of these in a 48 tooth.

One of these in a 14 tooth.

All tied together with one of these in "Bling, Bling" gold.
You'll need a 110 link chain for the 14/48 combo. It's a 520 gauge chain.

i have an 06, id go with 13/45, and a longer chain.... moose makes a sprocket for the front, and any KLX300 rear sprocket will fit the rear.....

 

Try the search function lots of good stuff.

 

06 running 13-45, oh and welcome to the forums, now get over to the new members area and give us a proper introduction. That's an order.[8D]

 

If your front sprocket is in good shape, I would just get a 48 or 49 tooth for the rear. It will give you about the same ratio as 13/45 and in theory should have less wear on the chain since you are not going around the smaller 13 tooth sprocket. You will also get to keep the rubber dampner with the stock front sprocket.

Either way you still have to get a new chain. 13 tooth only in the front and you can use the stock chain.

 

i used a brand called PBI sprockets both front and rear. they are available from a supplier called western powersports which most shops can order from. i went with 13 front and 47 rear after trying 45 originally. now i'm where i want to be. WestOz, i know renthal makes a rear sprocket for us, but i've never heard of a front. do you have a p/n? i used a longer chain, and went with EK, as the stocker was an EK. the chain corroded immediately even though i keep it properly lubed (and the chain too). i would use PBI sprockets again, however i think i'd try a different brand chain.

 

Take a look at the White Brothers rear sprocket. I just replaced myOEM sprocket with one of these and wasshocked at how much lighter the White Bros. was compared to the stocker. The price is right and the look tremendous. Check ebay for the one you want.

Hey Mike I hope you don't mind but that link was too long and causing the page to be too wide, I made a quick link for ya.

 

Hi all,

I seem to be a minority in that I want to change my sprocket combo for the opposite result as everyone here. I want to go with 15T front and 38 or 39T rear. Does anyone make this, and what size chain would I need to do this? I found one sprocket here in Japan that is 39T but it costs almost $80.00!! Any help is appreciated.

 

Well first of all, welcome to the site and the forums here. I think Dean could probably answer that question for ya. Be patient, he will be along shortly.
