Wanted: Rear sprocket 48 t for 690
« on: August 02, 2016, 04:53:45 pm »
Hi,

I am looking for a rear sprocket, decided to try 48 tooth, must be steel.
Usually I buy at Conrad at offroad cycles, but they dont have any stock, and I need one by the weekend.
Does any one know of a shop in PTA that will have stock? Or any Vendors that will postnet - postnet..

Thanks.
Werner

You can also try a 14T front sprocket, will be the same and you will not need a new chain.

Something to think about...

Thanks for the reply's.

Bill, I was told that fitting the 14T front, creates more wear on the swingarm chain sliders and front sprocket, as the circumference of the front gets to small?
That and my rear is starting to look like waves...thats why I decided to change rear.

Does anyone know if the OEM chain will work with 15/48 combo? will it be long enough?

Thank you,

Whats the reason that it is suggested to stick to incremeting the rear by 3 teeth? Is there some negative aspects going from 15/45 to 15/47 instead of 15/48?

I ran a 14T front without seeing any slider wear, however, it tightened up the gearing too much, making the bike feel slower rather than more lively.  If you are presently right at the back of the adjustment range, a 48 might still work if you flip the spacers.  I would rather go 47 for the reason stated, but again I'd rather go 14 front for the experiment.  It is cheaper as well as easier to swop.  If I remember correctly, any 520 pitch KTM rear sprocket will work, so getting a 49 or 50 should be real easy.  47 or 48 might be tough.

Thanks Bill. I tried most places in PTA, unable to get a 46 or 47 in steel, and you are correct, shares with most KTM models. I dont want aluminium, I think the 690 will eat it a bit quicker. And I checked, there is not enough chain for the 48, need another 6mm to adjust, but the axel is already against the swingarm....
http://www.gearingcommander.com/ is a good place to get all the questions answered.
So, going with the 14 front....
Thanks for all the replies..

Just check when you guys run the bigger sprockets on the 690, if have the chain set all the way to the front the brake line tend to rub against the swingarm, fit a rubber sleeve to keep the line from chaffing.
