tt 600 re sprockets
 

I know I've asked but Im wanting to increase acceleration..I have gone down to a 14 t front but want to try and gain some more.

Im struggling to find a smaller front sprocket but am able to get 45/42/41 T rear sprockets...

ANY opinions ??

Yes, buy a Yamaha R1! If you like offroader how about a turbokit?

I've had other people ask about stuff like this, To go so low for acceleration(usually to brag about popping wheelies in 2nd or 3rd gear) but then have it screaming at high rpms down the road. For offroad and not needing topend speed not so bad. Go with the 45 rear sprocket and the 14 front, if that's all you can get it's as low a gearing you'll get. I thought a 13 could be gotten along with 47 and 48t rears but maybe that's just over here.

Next up : big bore and high comp plus carb increase.

I should have said more..I had a balls out ccm r30 with a 710 big bore kit which I sold last year.Tbh it was too much.

I have a ZRX 1200 Kawasaki which was my 40th birthday present to myself.Im now 52.

I don't want to go fast or pop wheelies but I do want to be able to pull away from traffic lights etc ..

It only feels so slow because you have others that pull away, it will never be the feeling you want swapping the sprockets. I think maybe a KTM would be better bike for you, never had any problem pulling away with my xt with stock 15/45. It is what it is...and i quess you like to have some top speed aswell.

as said I GOT RID OF A SUPERMOTO THAT HAD TO BE RIDDEN BALLS OUT EVERYWHERE..A 1200 FOR SPEED ETC. tHE TTR IS FUN IN A DIFFERENT KINDA WAY BUT DEFO NOT FOR ANY KIND OF SPEED

Ok it must be something seriously wrong with your tt if you cant pull away from traffic lights, good luck with the sprockets....

A different rear tire that's a little smaller diameter and lighter does help on takeoff. An FCR carb would help in throttle response. There are a few things to get more of a hit from takeoff, just the more a person wants the more it costs.

Try to double check some other Yamaha models , there may be sprockets that will fit just not spec'ed for the tt. I've run into a few things from other models that fit.

Well he dont want the bike to go to fast.. not to slow.. and suggestion about KTM is all wrong, LC4 have 60hp same maintence and are pretty much the same as the TT. Maybe magic is done with sprockets i dont know..

I'm assuming it's an assumption that a 600 dirt bike will have equal performance as a 600 sport bike. Don't know.

For the xt600e you can source 13, 14, 15 and 16front, and just about anything from 40 to 50 in the back.

Thanks for the reply. I have tried to follow the link you posted and although it said it was translated it remained in german.

is the xt 600e sprocket set the same sizes as the tt600 re?..I have no idea and would even know if the chain will need shortening or making longer:helpsmilie:

There should be a flag on the upper right corner of the website, so you can choose between german and english.

I dont know if they're the same, but I would guess the front should be the same. My friend has a kick only tt600s belgarda, and we can change sprockets between us.

Or just look at the number on your current sprockets, and change the number that matches the toothcount with a smaller/bigger, and use google.

I would think they're the same in the front also . They had 2 different splines, the older course and a newer style that has about twice as many grooves/lands.

The 660 will be different though , at least ours is in the US.

ok..do I go down to a 13 on the front or up on the rear.currently running 14/47...:helpsmilie:

You already have a 47t rear with that 14 front ? Might as well go down to 13 front. Each front tooth difference is equal to 3 teeth in the rear.

This will officially be the lowest geared bike I know of, at 90kph the motor will be maxed out on the rpms. Sorry just can't figure this one out. I've always noticed when something is geared too low, it makes first gear worthless so you have to shift right away,and then again, which is slower takeoff than proper gearing.

4800rpm at 90, not too bad...

Its great for woods riding, especially on the xt600e, with the huge gap between 1st and 2nd gear.

Even with that gearing ? You sure on that ? I have 16/42 on my 3TB motor and it still is 3600 at 55mph (90kph), was 4200 with the 15 T. The newer ones must be really,really internally geared high. With 13/47 I'd be somewhere in the 5800-6000 range

As a comparison , one of my kicker xt's has 16/38 and it runs only 3300 at 55 (90kph) a little lower. These are just highway commuters, not real good offroad.

I understand you 100%, the 600 XT/TT yamahas are excellent bikes but a little soft in the engine department.

Your TT600RE has the exact engine as a 1990-1994 XT600E. So when you order front sprockets do NOT order front sprockets for the TTR600, they have the same spline pattern but are way thinner. The rear sprockets patterns are the same on the TT600RE and XT600E (but the TTR600 has a different pattern)

I, like yourself, ended up with 14/47 on my old TT600RE. It is a good ratio if one is riding below 100 km/h. I now have a XT600E and have tried a few different combinations of front/rear sprockets. The fact is that if you go too low you wont be using the torque of the engine effectively. You now have gearing close to perfect IMHO. Go one up on the rear if you want to change.

I have a USA model 1986 XT. Stock gearing is 15/42. I like to use either 14/42 or 15/45. This is the same 3 to 1 ratio. Unless you are hi way causing at lower elevations then I think this is the perfect ratio. Good around town and good in Colorado at over 14000 feet.

Thanks for the reply. Im guessing my 2003 tt 600re is a similar engine although stock gearing is 15/47.

NOT wanting to stress the engine,it already sounds like a bag of nails!

If its geared like the E model, it will do aorund 4000rpm at 100km/h (depending on tire) So theres plenty of room to gear it down.

Im running 15/47 for street with a SM tire, so going down 2 tooth in the front for the woods, with a taller rear tire isnt that radical at all.

Some where along the line I think that what I was originally asking has got lost.
To recap.
Im running a 2003 tt60re with a 14 front sprocket. Standard gearing which is,according to the owners manual 15/47.
I would like a bit more initial accerleration. Im NOT interested in top end speed and don't want to go offroad.

I appreciate ALL the advice already given.

Thank you

Did you manage to find a 13 CS sprocket?

I bought mine on the german ebay, its made by PBI.

Front sprocket is called "ritzel" cant seem to find anything just now, but they're there from time to time.

TBH I haven't looked as I didn't know w hat I was looking for. It's tonight's web mission. Thanks.:thumbup1:

I cant find a 13 tooth front sprocket ...whats the rear equivalent??

1 front equals 3 in the rear.

treat me as a thick bugger..if I was to want the equivilant of going down to a 13 tooth front on the rear what rear sprocket size do I 'want?...

47 + 3 = 50 :scooter:

Tank You..on the hunt..:D
