14T TTR125LE 2004 countershaft sprockets

Who has and where can I get 14T TTR125LE countershaft sprockets ? I can't seem to find any to order ?

Cher'o,

Dwight :)

They didn't have them listed on their website but did on the dealer side of site. It seems the XT125/200 82-83 front sprocket is the same. So Parts Unlimited has them.

Thanks,

Dwight

I found the TTR sprockets on the sprocket specialist website. I bought a 16 tooth for mine. Final gearing 16/49. Makes for a little more relaxed ride on the pavement. Pulls it surprisingly well. :)

You could fit a 16 tooth on the front? My 15 would BARELY fit.

Yeah a 16 sounds awful big for the front.I know my buddies 03 125L you cant even get a 15 in there because of the white plastic piece between the sproket & the engine case.I asume this is a cushion in case the chain comes off so it wont crack the case but im just guessing.

Yeah, pull the chain buffer and there's lots of room. :D I run a good 428 O-Ring with the BBR chain guide. I'm pretty confident that I won't throw a chain. If I toss a chain, I'm not sure how much that plastic thing would do anyway. :) Its a bit of a risk, but what the heck...

Whats the stock gearing? I dont know what I have on the rear or front and I have a Moose sprocket on the front, which I dont know how many teeth are on it. 16/49? Wow, that seems high. :)

13/54

And it sure is wierd how you can read and write but can't friggin' count! :)

It IS high for sure....we use it on the street only. I have an extra set of wheels for it... I run 14/54 in the dirt. the 16/49 definitely doesn't do too well up hills, especially with my fat *ss on it, but the wife can cruise along pretty well on flat ground and the motor isn't screaming its guts out ....she only weighs about 100 pounds.

Well, I tried the 14T this weekend with a DID 428V o-ring chain. Mods include minimal airfilter mods, slightly enlarged carb ( hogged out 3mm taller bore ) , 110 main jet, 20 pilot jet, FMF pipe.

This thing flat chugs up hills in 2nd gear. Sometimes third. I would say it needs a 15T sprocket. It runs great. I need some stiffer springs though. This is my wife's bike but I find it really neat.

Why are you running an o-ring chain? You know they rob power on these little bikes, right?

WRONG, a modern broken-in O-ring chain, that has been warmed up, has no more drag than a non oring chain and lasts so much longer. I have only about 5 miles on this one and can't tell I have an oring chain on the bike. You primarily use yours for Super Motard and it sees little or no dirt. I can see why you might go non oring. But I have been using O-Ring chains on my bikes since my days with Team Suzuki Enduro. I had one on my PE125 ( prototype ) and it took then about 50 to 75 miles to break one in. You could tell a big difference back then. These days break in is probably less than 10 miles. Modern o ring chains are very good. You could probably tell about the same difference if you ran a different brand spark plug.

Donkey,

For your road race application it is common knowledge that O-ring chains have considerably more rolling friction and cause more HP robbing drag than high quality non o-ring chains.

For those of you who disagree, consult the sportbike roadrace & drag race communities.... Schnitz Racing, Brock Racing, even DID's 415 exclusive race chain does not employ any form of lubrication rings, and it can handle nearly 50HP. DID even makes a non-ring 520ER chain for 100HP bikes!

I think even BBR states that these 7HP+ bikes only need an O-ring chain if you continue to "ride under water."

I don't care what they say, Prove it on a dyno ! I bet a used standard chain on a road bike will have as much or more drag than a good used O ring. Thinking that O and X ring chains have more drag is a Folk tale and nothing more. I can see how a drag racer may not want to use one as there is no warm up time. Go take a look at a modern O or X ring chain you will find there is very little drag. ESPECIALLY when warm. I have on on my bike and can't tell difference in power. So that is a good thing. I was a factory rider and we used O ring chains for reliability, because there wasn't anydifference in power. You will get more of a difference in your viscoscity of your engine oil.

I did say if you are road racing that you might not use an O-Ring chain but it ain't worth it for off road.

IMHO

I actually had several chains in my hands the other day. The 428 o-ringers were considerably harder to move around. The links were VERY stiff in comparison to the 428 non o-ring chain. The 520 o-ring that came off my buddies CRF150 was absolutely ridiculous. Warm up may help a little, but on a 7-10hp bike I feel like you need to take advantage of every opportunity to conserve power.

I have been watching this thread with interest. I have dyno runs with a TTR with a used but good "o" ring, a top line new 428 and a new 420. The 420 is the least power robbing but not much over the 428. The "o" ring took power very noticably. I have also done a XR100 (my CRF100)with 420 compared to 428 and same outcome. Lighter chain is better. I used JT sprockets on front and Sprocket Specialists aluminium on rear. DID chains. On a bigger bike it might not be important but for a TTR / XR100 IT is important when trophy hunting :)

Awwww, Come on now. You know I said a cold O-ring chain is stiffer. A warmed up one is not noticable. Now the CRF150 is made in Brazil isn't it ? It uses a very cheap made 0-ring chain. It may be stiffer until well broken in . I will drag race anyone of similar weight and mods. I will bet there will be no clear winner . BUT the O-Ring will last 10 times longer. Your sprockets will last 4 times longer. The chain will need very little adjustment throughout it's life.

Reliability is greatly enhanced. What more do you want ?

If you can measure .2 hp difference I will be surprised. By the seat of my pants I can't tell difference. If I can't tell difference then there isn't enough difference to tell.

Cher'o,

Dwight

PS: ( I will concede you may get an additional 1.3865 mph on top end )

Renthal claims a 3lb unsprung weight loss and 2hp gain with the 428 non o-ring conversion for the CRF150.

Ever think it was possible that you may not know it all, Dwight?

Where are YOU getting these figures about chain and sprockets lasting 10 and 4 times as long? As long as what? Who did the study?
