Chain and sprocket changes
 

Im wanting to increase the acceleration on my ttr e 600 and its a happy coincedence that my chains dead..so what sizes do i need to increase the acceleration?..any make better than any other?..

I have change to 14:40 from 15:38. Makes a hughes difference, and its now really fun to drive. And i can still drive 120 kmt with out problems.

Does the chain length alter when you change the sprocket sizes?

It dipends. I my case it did change a lot. But you can buy chain kit where it fits with the ratio you choose.

After searching it would appear that a chain and sprocket kit is only available in either standard form.15/47 or14/47 as an alternative.

Anyone know if any of the xt's etc chainset is the same and transferable?..

Buy both sprockets and chain separately.
Both rear and front sprockets come in variety of tooth numbers, and you can lengthen/shorten the chain to your needs by adding (if necessary) a bit of chain, securing it with two master links. Shortening is easier, requires only one master link.
But I don't think you will need to change the length of the chain if you won't go to extremities.

Cheers! bier

unfortuatly im being told by various suppliers that NO alternative rear sprocket is available for the ttr...

Hi Nik ,
Is your TTR the Cush Drive one - if so I think the Sprocket may fit from an XT , double check with Supersprox , if not WR's sprocket fit I think ditto check with Supersprox , by the way did you sort out your carburation ? All The Best Glenn

rear sprockets
 

hi have a look at this site ,http://www.jtsprockets.com/ ,available in the uk ,they make great sprockets hope this helps steve

Go to gearingcommander.com i know the xt is on there. You can put in different front/rear sproket sizes and it'll show how it changes acceleration, top end, bottom end, torque ect ect also will show how many links to add/remove for what ever you decide to go with.

I found it usefull.

Hi Glen..I have just finished putting it back together after a lot a faffing about.I have been putting a ttr 250 back together so I can hopefully sell it.

Its not been out yet but I did change the idle jet,up one size,after advice recieved on here.

I have to set the idle speed air/mixture screw next week and will follow advice from here on how to do it.

I stripped the carb and used a can of good quality carb cleaner on all the jets and air passages including the choke mechanism.I also used a compressor to blow through all the airways. Starts sooo much easier now.

Appreciate ALL the advice given. Saturday morning reasearch time.

BTW I thought all ttr 600's were cush drive?..Dont wana strip the back end out to find out tbh...

The TTR600 did not have a cush drive.

The genuine yam service manual identifies that the ttre does have a cush drive...refers to it as a 'damper'

Yes, the TT600RE has one. But the TTR600 does not. The TTR600 was more of a dirtbike, and did not weigh as much. It did not have the e-start or the cush drive.

edit:
I see you wrote "ttr e 600 " in your first post, if you have e-start you have the TT600RE. It has a cush drive. Please note that you need the front sprocket from a suitable year XT600 and not the ttr600, the sprockt from the ttr600 is to thin. If you order from wemoto you probably will get the wrong part. I did.

If you have a 6-bolt pattern on the rear sprocket you have the TTR600. If you have a 4-bolt pattern on the rear sprocket you have the TT600RE. From memory (please check before ordering) it is the same as the XT600 has. You should be able to get lots of different sprocket sizes if you have the TT600RE.


I had a TT600RE and changed from 15t to 14t up front. The rear was stock, 47t if I remember correctly. I was happy with the change, the bike was a lot more responsive and would cruise happily at 90-100 km on the blacktop. For higher speed (like 120 km/h) I would have kept the stock gearing.

Revival
 

Hi all.
Just got the tt600re back after it had sat in a potential buyers garage for nearly two years..he's a mate and I know its been un used.
Never did the sprockets n chain so im going to do it now. Just to confirm the sprockets are same as the xt range....:confused1:

Yes they are. I just put a 47t TT600RE sprocket on my 2000 XT600E. They are the same except for the number of teeth (47 is stock on the TT600RE and 45 on the XT600E).

The TT600RE and 2000 XT600E front sprockets also are the same. The TTR600 had a different sprocket and so did the early XT's, don't know the exact years.

Thanks..best go count how many teeth I got on my sprockets.
previous advise suggested going from 15/38 to 14/40..

14/47 on mine as is...

Yeah, me to. I went 14/47 on my XT600E when I replaced the chain/sprockets last week. Great around town, excellent offroad but a little buzzy on the blacktop. About 4k rmp's at 90km/h, 4,5K at 100km. The TT600RE is more off road oriented, I liked 14/47 on my 2005, but I was not really looking for comfort on the road.

I will go 15/47 and see how that works out.

I;ve started to use het to commute,18 miles each way and mostly country backroads..making the journey 'fun'. Engine rattles away and im maxing out at 45/50 intentionally.

Not sure what going to a 15 up font would do tbh.

I did an oil n filter change yesterday and have never had as bike that's so hard to check the levels as this one. Royal pita!

Gearing is a very personal choice, and greatly depends on the driving pattern. I've gathered a lot of different sprockes over time (13, 14, 15, 16 cs sprocket, 42, 45, 46, 47 rear) and tried most of the combinations.

I've commuted just over 100km a day, for almost a year, I used 16/45 for that to take the top of rpms when riding highways, interstate ect. I've also tried 13/47 just to test it in the sand, but the gearing was too short for me, couldnt really use the torque of the engine, and the XT will never be a high rpm screamer.

I have a few different sets of wheels, but I would agree for everyday fooling around, commuting in town, and not a lot of riding ont he fast roads 15/47 is nice. If going on some gnarly track, change the front for a 14.

I hated stock gearing the first few years, but now it seems like its actually really good for me. I think I've gotten used to it, and my driving pattern has changed a bit. Perhaps I even carry more speed on the gravelroads ect, to suit the gearing.

Its easy and cheap to play with the front sprocket, the rear aint that bad either when you shop around. A 15/47 combo fits with stock chain as I recall.

Happy hunting.

how will going to a 15 upfront affect the bikes feel?..

15 is stock, together with 45 rear.

1 tooth front alters the rpm by about 500rpm. So going one tooth down gives you 500rpm extra at the same speed.

So if 15/45 gives you, lets say 95km/h at 4000rpms, changing the front sprocket to a 14, will set the rpms at 4500rpms to go the same speed.

You can play with the numbers at www.gearingcommander.com I use the 1990 xt600. I added that one, and its the same from 1990 and up to the last models.

on the tt600re stock is 14/47...I was wanting a bit more go from the off so if I understand this correctly,be a first, going to a 15 front tooth would drop the acceleration whilst effectively lowering the revs at the top end?...

Yes, try it, CS-sprockets are cheap.
