Hey all im changing my sprockets and chain on my 1999 Blue TTR250, was hoping someone could give me a little advice and check out the sprockets and chain kits on Ebay im looking at. I just dont know whats best or what will or will not work, price dont matter as long as the product is good. So what do you guys think is the best one?

I agree that you should check out Brian's sprockets as he only stocks the good stuff wink

If you want to see what fits see this thread

I only use o-ring chains because they last longer. More expensive but well worth the extra coin.

If you sent an e-mail asking for details I think it could all be catered for. confuse

Take a look at his LINKY THINGY and make a list of what you would like TotallyTTRs to send you.

Now write an e-=mail itemising your requirements to sales[@]totallyttrs.com (remove the square brackets first)

For non UK orders it may be best to utilise PayPal to arrange the currency conversion bit. wink

Brian (or Trish) will then give you all the details you need to place and pay for the order and then you sit back and wait.

Simple, painless and rewarding. biggrin

If you email him with what you want and your location he will be able to quote you on the parts including delivery, it maybe that with the shipping costs it works out quite expensive but it will be worth asking. 

Ps. They are very professional and helpful

Hi Jon

Just send us an email with what you would like, along with your address, and we will send you a quote to include shipping to Canada so you will know in advance exactly what your parts will cost in total.

For heavy items, like chains and sprockets, it is often cheaper for overseas customers to buy locally but, in some parts of the world, this isn't possible and we can fill the void. 

However, it doesn't hurt to get a quote smile

See here for full details.For overseas customers, we invoice via PayPal in UK£. Currency conversion information at the bottom of the information.

We have quite a few happy customers in Canada biggrin

Any questions, just ask wink

Regarding what type of chain and sprockets to buy, pretty much any steel sprockets will do the job but we now only stock Renthal R3 chains as they are one of the few types of chain that can put up with the abuse my mates give them on their WR450Fs wink

Similarly, the WR450Fs round off the cheaper steel front sprockets quite quickly and we have found that the Talon front sprockets last longest.

Obviously the TTR is not going to put the same strain on the c&s as a WR450F but we all want the best life out of our gear.

I find that, as a rule of thumb, I get through two front sprockets (and split links) to one chain and one rear sprocket whether it be alloy or steel. A good make of alloy rear sprocket such as JT, Renthal or Talon will last the life of a chain on a TTR250 despite what many owners think and is a big weight saving especially if you are running big numbers such as a 52T.

Hope that helps.

Brian

Thank you very much, only thing is...does it matter if say i have a 13-44T and change to a 13-52T? Does it matter or is it all preference?

It is up to you but the gearing you use should be related more to your riding conditions than your riding style, in my opinion.

These are my views and there is a lot more information elsewhere on the forum.

  • Purely road use 14/44
  • Extreme off road 13/52
  • Mix of 50/50 road and occasionally tricky off road 14/52 or 13/48

Is there a big difference in the 13/52 and the 14/52 or 13/51?

Yep. Changing the front sprocket in particular has a big effect. Proportionally a one tooth difference on the front is bigger.

Sorry about that Jon. You haven't done anything wrong.

Trish and I link our business email - sales@totallyttrs.com - with our private Hotmail addresses so that we can deal with all our emails at once in Outlook. However, Hotmail has got huffy with our business ISP (1&1) for some reason and is bouncing emails.

I have reported this to 1&1 and hope they can sort it out soon. 

We have been getting quite a few emails through to sales@totallyttrs.com today so I am a bit confused about the whole thing.

Perhaps you can send me a PM (Private Message) on here and I will get back to you as soon as I can.

Sorry about the hassle.

Brian

Yah my bike already has a 13/52 so im stick with that, i just drive around my small town and do offroad. I dont plan on riding highways its kinda scary on a 250lb bike LOL i got a trailer if i want to go anywhere far. Just checked my front sprocket and there is 4 teeth missing LOL so i guess its time to change them. Thank you for everyone you all have been nice and informative, i hope all i need to change is the small stuff.

To change the front sprocket is it counter clock wise to take it off? i just dont want to crank on something if i can ask an easy question.

Yes, anti-clockwise will take it off. Beware, though. It may well be difficult to undo.

Stick the bike in gear, stand on the rear brake, socket on the nut, LONG tommy bar for leverage and heave ho. 

Some people have had the same problem! See THIS THREAD

I was reading this and I starting to be curious about what would happen with a 13/52, I have a 14/52. One tooth from a front sprocket would be as three or four from the rear sprocket, probably a 13/52 can be equal to one 14/56 (obviously, there is not a rear sprocket with 56 tooths).

About what have I bought? I added the front and rear sprocket from http://www.jtsprockets.com/  I payed 32€ by the JTSPR-C-0853-D52 and 22€ by the JTSPR-C-0853-D52. The chain was a Regina 520 ORC6 O-Ring and I payed 45€ by it. The Renthal chain can be excellent but I do not think that a TTR250 needs a super chain, with one cheaper it will be enough. I have made by the moment more of 2500 km of offroad use and the chain is very correct. Of course I´m the typical guy who he cleans the chain too much.

13:52 = 4.00

13:48 = 3.69

14:52 = 3.71

For ultimate sloggability your choice for rear sprocket with a 13T front would be 52 teeth giving a final ratio of 1:4
a rear sprocket with 50 teeth gives 1:3.8
a rear sprocket with 48 teeth gives 1:3.7
a rear sprocket with 46 teeth gives 1:3.5
a rear sprocket with 44 teeth gives 1:3.4

I edited my previous answer with some of new information about what I added in my TTR.

13:52 = 4.00 is there any thread when I can read about the attitude from the motorcycle with this option at each gear? with the 14/52, the 1ª and 2ª are short and very good but the 3ª continue being too long without too many resistance. Of course I should test it if I can (a front sprocket is cheap and probably I can test it without cut the chain again) but I´m worried about if it abrades the rest of the piece 10 (look image).

At the end, I have replaced the 14 front sprocket by a 13. Now I have a 13-52. The change is big but nothing very impressive. All the relations are shorter and the motorcycle accelerates faster but perhaps it is not perfect because the 1st and 2st and even the 3st are shorter and a different way of ride is necessary. I hope that I like it more with the past of the time, at the end, I replaced the my 14 because it was deteriorated.
