Hi guys!

I dont write often on the forum but I look at it everyday and I know I'll get good answers to my questions here.

I already changed my front sprocket to 13t last fall to gain force in the low gears and now I wanna change the rear one too since I dont do any high speed. If I read correctly, I should switch to a 47t in the back and a 108 link chain to accomodate the change. First, can you confirm this.

Then, do you think that I need the more expensive chain (dealer mumbled something about o-ring)? And, do you think I should go with an aluminum sprocket or stick to plain old steel?

Thanks in advance for the response.

Go 45 on the rear, and yes 108 links in the chain. You'll then be able to up gear to 14/45 very easily and the 108 link chain will work here too.

Go with what you can afford.
I run the Renthal R3 520 'o' ring chain with a Renthal 'ultralite' rear sprocket (45 tooth) and have not needed to adjust the chain in 6000 km. The KLX isn't a powerhouse and 520 chains can be found on 100hp bikes of 750cc or more. As we ride a lot of sand it's nice having the 'o' ring chain and knowing that not lubing isn't wearing it prematurely. (Sand and chain lube' = short life on your drive chain and sprockets.)

Steel or alloy sprockets, it's your choice. They both have their + points.

 

I run a 14/47. Since you already have a 13T, I agree with WOZ's suggestion on the 45 for the rear. A 13/47 would be too low for my taste, even for aggressive, technical, and tight terrain...and pavement use would have your engine screaming in 6th gear. Other's preferences may vary. WOZ is right on the issue with your ability to flip back and forth with a 14T front for times in the future when you might want to do more pavement or open terrain. My 14/47 is right at the extreme margin for what I feel comfortable with when having to hit a decent stretch of highway as far as rpm's go.

 

See!?! that's what I mean by quick response and good advice! Man I love this forum!

Thank you guys, order is now placed.

Marco.
