2005 Yamaha TT600RE – a few questions
Hi all.


I am new here, just bought a 2005 TT600RE. Love the bike so far, I have had it for 10 days and ridden 1000 km. Great fun on and off road, it is a fine do-it-all bike.


I have a few questions:


1.Does the TT600RE have the same engine as the XT600E? Or does the TT600RE use the same engine as the TTR600, only with the electric start added? The TTR600 (non-electric start) engine is supposed to be 30 mm. narrower than the same year XT is that true? Why?
2.There seem to be two different engines in the recent TT600 and XT600 models (see picture). Can anyone tell me why that is? Different engines for different models? Different years? The clutch actuation is different in the two engines. And the engine casting is not the exact same.
3.I have some sort of a snorkel-thingy in the airbox (restricts airflow). Should I remove it? Must I rejet if I remove it? The bike has ample torque/power but there is a flat spot in the powerband just before the second carburetor opens (I think). How can I get a better and more “seamless” powerband?

Hi
On the TTRE engine the generator cover is about 30mm wider as there is the starter clutch under the flywheel.
The cdi is differnt on the TTR and the TTRE
The TTR and TTRE have differnt gearing as the rear sprockets are 44 on the TTR and 47 0n the TTRE.
Not sure about the snorkel on the carb.
I think the engine with the clutch lever on the right (circled) was the last of the XT600e engines.

The gearbox with the clutch lever on the right is the(better) later one which doesn't have the 5th gear wear problems the earlier ones had.

Thanks guys, great info.

Bobmech, can you please explain the 5th gear wear problem? What happens? Does the engine get noisy or will the gearbox brake?



My bike is a TT600RE 2005, I read somewhere these bikes are made in Italy, but using Jap engines. Does anyone know if that is true?


Are there any known weaknesses in the TT600RE 2004-2005 that I should address now or keep a close eye on? Gearbox problems?

Ive got the same bike as you and very happy with it, there have been many Threads on here about 5th gear problems as long as you are aware of it it should be OK just dont labour the engine in 5th, just adjust your riding to suit, I'm not expecting any 5th gear problems on my bike now.

On my TTR VIN plate it says made in Italy
I also heard the engines come from Japan and the bikes are built in Italy
Not sure if all the TTRs are built in Italy or just the 600s

I'm interested to know how Italian my Bike is because as soon as I got it though a nice bike I didnt think it was Japanese quality ?

Ive tried checking online but there doesnt seem to be too much info on TTR600RE's except on here.

the ttr's are jap reliability with italian style/finness so just enjoy the fact that it was probably built in or close to the belgarda factory where the moto gp bikes are developed and built.

TT600R 1997 on and TT600RE's were built at the Belgarda factory, Gerno Di Lesmo, Italy. Hence Paoli forks, Tomaselli bars, Regina chain, Domino grips, Acerbis plastics etc. The engines are from Japan. This caused confusion when filling in paperwork on the Pan American borders as all the officials would try and insist that the bike must be made in Japan as it is Yamaha!
There are a number of differences between the R and the RE. The RE has electric start, no kick. Sachs shock instead of Ohlins and sits approx 50mm lower. Forks on RE are adjustable for pre load only, R for rebound and compression only. Different gearing and cush drive on RE. Lights wired on and cheaper swichgear on RE. San remo rims on RE versus Tagasako on R.
The ride is harsher on the RE due to less plush suspension, but the magic button is nice when you are sweating your arse off in the middle of nowhere.
I have 2 TTRE's and a TTR in the garage, still room for a new tenere i reckon.

Guys, thanks for the help. I really appreciate it.

So the “weak point” in the TT600RE seems to be the 5th gear, and I may expect problems after 30.000 km. I don’t know if a rebuild at 30K qualifies as a problem, most of the bikes I have had for the last years (RFS’s and two stroke enduro/MX) will not make 30K before they go to the scrap yard :-)

Seriously dont worry about it just use 4th gear until you are going a certain speed.

My previous TTRE had about 50000km on it with no discernable problem. Keep it at 105kph plus in top and don't let it too much.
