i have on the bike atm a 520 renthal chain and sprockets.

they sent me a 427-11 front sprocket

i dont think it will work with my 520 chain

or can i use it?


was there a 427 chain stock on the rm 125 from new?

427-11 is just a part number.

There is no 427 chain size..

As far as I know, dirtbikes usually only use 520, 428, 420.

But why would you want a 11 tooth sprocket? that's a bit small..

so it will work?

i wanted a smaller sprocket to get the feel of the gearing before buying a bigger rear one

i looked at ratio charts and with a 11 is just like adding 4 teeth to rear

According to JT Spockets site that sprocket is for a 79-82 RM100 with the 520 chain conversion. Also according to the JT site you would need a JTF 427.12 check this link for both parts #'s http://www.jtsprockets.com/61.0.html?&L=0

hmm not sure if i should even try putting it on the bike

 

[IndyMX]

I'm betting it will..

I'm betting it will..

Given how JT cross references each year and bike a part works for I'd be very reluctant to try, especially since it's a $10 sprocket. I'd chalk it up as a loss or ask the seller to make it right.

That $10, 11-tooth sprocket will stretch that $50+ chain out into junk in no time at all.

well it fit :) the chain is on its way out anyway.. i am just doing this to get the feel of it. if it works ill get a bigger rear sprocket.btw hill climbs like i do will stretch the chain out no matter if it has a 11 or a 12. i am always adjusting slack out of the chain...
