13 tooth CS sprocket for xt600e, availible?
 
Hey gang...

I've been messing a lot with the gearing on my 2003 xt600e, as I use it for every possible way to ride. (everything from enduro/singletrack to interstate)

Ive got 14-15-16 cs sprockets, and a 47 at the rear, and a 140/80 tyre.

The 16-47 is nice in general when on the street, and can handle some big gravelroads aswell, tho its more fun with lower gearing.

The problem is that the 16 tooth takes som "effort" to change, as I need to take the chain apart (I have clip-type link) but it still takes some time. The 14 to 15 swap takes no time, as my CS cover/guard doesnt require the gear lever to come of, and the chain doesnø't have to be split.

So heres the question, almost:

I would like to use 13-14-15 together with a 44 rear. That should give me the same gearing as now, but without having to split the chain. Just remove the cover, the big nut for the sprocket, and loosen the rear wheel and the brake caliber mount, and im practicly done with it.

So do anyone know where to source the 13 tooth sprocket? Perhaps other models fit with a spaccer or something?

The 13 is only for when I know im going to tightass enduros, cross circuits and so on.

Thx in advance, Jens :scooter:

maybe GYTR makes them for the raptor660!

Cross reference between JC sprocket website and the Yamaha GYTR performance parts for the Raptor!

check all raptors, grizzlys and rhinos!

For example, I've cross referenced that the GYTR rear sprocket for a raptor 660 fits on my 1990 XT600E so... you get what I mean?!

Hey Jens.


I am curious, when you run 16-47 aren’t you straining the engine at low rpms most of the time (as in danger of the fifth gear problem)?

I’m just curious since my TT600RE is supposed to have the same engine as the XT’s. The bike had 15-47 gearing stock and I found the gearing too tall even on the blacktop. Maybe I am too focused on keeping the rpm's up on my bike..

Jens Eskildsen 15 Aug 2010 19:17

Its only the older ones that have 5th gear problem.

I've opned up mine, and rejetted it so it has some more upmh and low end pull......cruices at 90km/h at 3500rpm. 110km/h is around 4300pm as I recall.

I've used 15/47 for the most of the time, could live with that also I guess.


I found a 13 tooth on the german ebay, dunno if it fits, but i've made an offer.

If that doesnt work, Ill find my 14 tooth, look at the numbers, and google the hell out of the internet in search for a 13 :D

Hi Jens

I think the post from GS600 above has a lot of sense in it. Additionally, I can just remember an article, long ago, on sprockets. It was said that those who use sprockets in an industrial context don't ever use sprocket of less than 17 teeth, because of the enormous stresses which act on the sprocket and in your case and mine, the engine.

I wanted to use a bigger front sprocket because of this article (and compensate at the rear) but there is no space on my bike, because of the gearchange shaft. It's very close with a 16/17 tooth sprocket, and It cant take a bigger one.

I suggest some online research for general articles on sprockets... not only for bikes, to get info.

Will be no problem for me, but thanks.

A lot of dualsports uses 12-16 so I cant see the problem.

You cant just stick a 18 tooth on abike, even if it fits, it will not interfer properly with the chain"sliders" on the swingarm and such.

The 13 and 14 sprockets will not be for everyday use, just roosting around the tracks.

But thanks anyway :thumbup1:

Theres still a day left on the auction, and havent been ablo to gogole me to a 13 tooth, using the productcode for the 14 as a guide. (the 14 is jtf577-14)

The closest I've been is something like this: Front Sprocket Yamaha WR 250 91-97 13 Tooth: eBay Motors (item 220569830644 end time Sep-06-10 14:36:42 PDT)

But the collar isnt big enough. One could probably saw/grind of the existing collar from a known-to-fit sprocket (like an old one) and use that as a spaccer. Dunno if I would eb able to saw og grind in the c45 steel :S

The search continues.

Please do keep us updated…

Also, If you contact them I'm positive they'll have a solution for ya!
They'll either tell you which other sprocket models have the same design pattern (JTF577) or even make one for ya!

G600, Thanks, really....Nice to know :thumbup1:

Bacardi, yeah, but still cant find one from JT.


But I've won the auction, hope the guy will ship to me in Denmark, it only said Germany in the auction, I knew that......What a bad guy I am :innocent:

13,83 euro, withouit shipping, not bad at all for a sprocket I cant seem to find elsewhere. :clap:


The story goes on

bacardi23 18 Aug 2010 13:42

Good luck then =)

I'm still dealing with the swingarm, what a b:censored:ch...


Vando :cool4:

Jens Eskildsen 25 Aug 2010 21:37

I got the sprocket, and it sure looks like it will fit =)

It says "441 13 P.B.R." stamped into the sprocket. Does that ring a bell for anyone? I cant manage to find anything on uncle google.

bacardi23 26 Aug 2010 00:45

Just try it on then and report back!

The sprocket should have 22 splines...
=P

Jens Eskildsen 26 Aug 2010 08:23

Yeah yeah, but I would like to find a source to buy more =)

bergman501 26 Aug 2010 16:36

google PBR sprockets===441 looks like it the right one
