Hi guys.


My 2005 TT600RE will need some new sprockets and chain soon. I may lower the ratio a little from the standard 15/47 it has now, but that is another story.


I am a little confused though, since what I have read is not consistent. Please tell me if:

1. The front sprocket on the TT600RE is the same as on recent XT600/TTR600 models.
2. The rear sprocket is unique, and only fits the TT600RE. The rear sprocket from a recent XT/TTR will NOT FIT?
3. The TT600RE was only made for two years, 2004 and 2005. The rear sprocket on the 2004 TT600RE is unique for that model. (I read this somewhere on the HUBB). If so, has the 2004 TT600RE a different rear sprocket from the 2005 TT600RE?

I did look at the WEMOTO website tonight ( Yamaha TT 600 RE 04 Replacement Parts at Wemoto ) and they only list spare parts for the 2004 TT600RE (and not the 2005 TT600RE). If I order some sprockets from WEMOTO for the 2004 TT600RE, will they fit my 2005 TT600RE?

BTW, have you guys had any problems with WEMOTO? Should I order from someone else? Who?

hi, yeah the TTR has a 44 rear sprocket, and the TTRE has 47.
not sure about XT tho, and if the TTR / XT sprocket would fit on the TTRE,
but if I were you I'd stick with original set ups (the TTRE also has a cush drive).

i have a 2003 TTRE, so they've built them from the end of 2003 to 2005.
as far as i know, there is no difference in the models.

I have always bought parts from Motoward and they are great, very knowledgeable, very helpful on the phone and very efficient.

hope this helps a bit.
and congratulations for the TTRE you bought.... it's a great bike!

Wemoto have always been fine for me. I have a flasher relay on order with them at the moment. Last time I ordered something from them, they sent two smashing little loop things to act as key fobs. One is used as a key fob, the other replaces the broken tab on my right boot zip and is performing brilliantly. Clunky website, but a good company IME.

I recently bought a rear sprocket for a TTRE rear wheel I think it is the same as an XT rear sprocket.
The TTR rear sprocket has no cush drive and the mounting holes are differnt.
If you can get a Kedo catalouge there is a section that shows the differnt type of rear sprockets for differnt model XT/TTR
If I need advice on what fits or will work on what XT/TTR I usually ask Dave Lambeth.
I have delt with Wemoto and good if you are sure of the parts you need.

Thanks guys.


Bolla, you are right. I took a look at Kedo’s website and they list the same rear chain wheel (part number )for various models:


“91524 47Z Kettenblatt Stahl 17.90 € XT550,TT600RE,XT600/Z/E+K,XTZ660 (passt nicht für TT600R)”


This is great news since a “special” item is less likely to be kept in stock, and I need a sprocket now. I went for a 2-300 km. ride today, mainly gravel roads with some off-roading in between. The wear on the sprocket was just silly, I could see some glittering metal grindings on the fork. The sprocket was bad before the ride, but it was totally ruined when I got home. The chain did stretch like rubber, I did adjust it before the ride and had to do it again mid-ride. Boy, this happens fast….

I am confused as to why you want to change the ratios. I find them to be spot on as an all round set up, Yamaha do look at these things when they design a bike, so if I were you I would buy the genuine Yamaha chain and sprocket kit from a dealer (£110 I think). You get a nice new Regina chain and two new sprockets which will last at least 10,000 miles if you look after them. Once a chain starts to wear it will go rapidly downhill, allways replace the chain and sprockets as a set.

Leigh, when I bought the bike two weeks ago, I thought it was a heavy dualsport similar to a ’93 DR650 I once had. I was going to use it for traveling and for some fun and easy dualsport rides after work and on weekends. The only off-roading I planned for this bike were some easy jeep trails. For the “real” offroad riding I was going to use my KTM EXC400.

To my surprise the heavy and short-suspended TT is also pretty good off-road. It is stiff and stable, tracks well and is not wobbling all over the place (like most of the heavy dual sports I have ridden) in the loose rocks and sand. It is not as comfortable on the road as I expected (harsh), but a lot better off-road.

The main limiting factor off-road are the street tires (avon gripsters), they are good on the road but horrible offroad. So I got thinking… maybe I should get a second set of wheels with some knobby’s on them, and give my KTM a brake this summer?

The TT600RS will never be in the same category as the competition level offroad bikes but I do not care, I do not compete, just ride for fun. My KTM requires a lot more maintenance (both work and money) and I also will need to buy insurance for the summer.

So now I am considering what to do. Maybe I will buy some new wheels for the TT, maybe I will adapt the wheels from the KTM so they fit the TT, maybe I will just get the plates for the KTM… But If I go for a second wheel set with knobby’s for the TT I would like a little lower gearing for the more serious off-roading…

So that is why I am looking at the possibilities regarding a different gearing………………

I can recommend www.offtheroad.de for sprockets etc, they list a range of sizes for TTRE's. If you use the Yamaha kit you will need a Regina 520 o-ring split link (forgot to mention on previous post).
