So I fitted my 13/52 gearing today and had a bit of a ride down the back firetrail
this combo seems to work really well, I can go down to almost stopped, and move so slowly in first gear that it doesn't even register on the speedo
I normally have my Idle set so the motor is just above stopping so you get a really good slow engine brake down hills but have now turned it up a bit this gives me a better response right off idle when I crack the throttle
It will also lift the front wheel quite easily without having to pull on the bars to get the wheel up
I'll give an update soon to give the maximum speeds I can get in each gear, I don't really care much though as I spend most of the time off road anyway As long as I can cruise at 100kph that's as fast as I want to go on the road.
Also 2nd gear take off's are going to be the norm now with 1st gear for really tricky terrain and tricky up-hills etc....
I got my new sprocket from "The Chain Gang" There in Brisbane I think It was expensive but is suppose to last 3 times longer than normal sprockets
Here's an overall shot, I need a new tab washer, I hate those thing, 2 uses and there buggered, Oh well I guess I won't be changing the sprocket any time soon though
I removed the chain guide and replaced it with this 3mm aluminium shape to protect the chain and sprocket from rocks
what a pity yamaha don't make an alternative nylon rear chain guide for the 52T.
the US model has 52T I believe, but unfortunately a different attachment point for the guide.
Yes, anyone that owns a ttr250 here in Canada would have recieved the stock US 13/52 gearing. Personally, I switched to 13/46 for the best of both worlds. But that 13/52 is some appealing for the very tightest of woods.
I've heard great things about the chain gang gear wears really well .and well worth the money
they claim its due the use good materials and the sprockets are machined to much higher tolerances than the usual run of the mill ones ensuring the best possible chain and sprocket match maximising contact area and longer wear is the result
only problem I have a case of short arms and deep pockets and don't spent the extra to get the benefit
and I run 13/48 find it good all round

My USA bike came stock 13/52 and I love it. Im a big fat American (260lbs) so its perfect for me. Its not street legal so I dont need it to go fast. Im perfectly happy with its top speed. I wouldnt want to go any faster.

LOL, at least your honest !
Hey I like the B&W TTR, maybe I'll recolour mine in a grey scale look
where I live I have my local loop, it's about 15klm long and it goes from:
fast open fire trail twisty fire trails really steep uphills an downhills really steep uphills an downhills with rocks and ledges thrown in shallow rocky creeks tight twisty single tracks just wide enough for the bars
In short everything I like in a ride and the TTR takes it all in it's stride, easy
At last it's the Weekend, here anyway, can't wait to give it a good test tomorrow. Oh ****, it's already tomorrow, 12:15, off to bed now

i recently fitted 14/51 gearing (couldn't find the 52 rear sprocket)...plus a new (cheap) chain..
compared with previous 14/48 gearing im happier now...bike moves as i like at low speeds on tricky dirt passes..
also top speed on highways back to home, not changed dramatically...so its ok for me...
Fwiw, I've used 13/50 gearing on my TTR for 70,000 km, and still use the stock chain guide. OK, the chain has to run up and over the bottom slipper, but I've had no problems with this setup at all. I've had a Chain Gang rear sprocket on my bike for so long that I can't remember when it was fitted (geriatric comments can be left at the door, thanks people). I have had a front Gang (13T), but found it didn't last any longer than anything else. Things may have changed since then, of course.

Today I have tried to fit a (new) rear JT 52 rear sprocket with front (old) jt 13 and 110 links chain (old) just to try the bike..... and....fail.
In my ttr it is not possible to fit the rear wheel axis.
Tomorrow I will try to fit a new set 13/52 112 (new sprockets and chain). Hope I can take out the old front sprocket because today it has not been possible .
[offtopic] I lowered my ttr 4cm with totally ttrs lowering link, feels great .[/offtopic]
That is the one I've got... but perhaps it will be a better choice go to the shop and change the chain for a 114-116 links one, since my 112 links chain is sealed in it's box and has not been opened.
Or as you say, petenz, buy a 120 links chain and cut it

Sorry, sorry sorry... it was a 108 links chain not 110, I think 110 will fit ok, because 112 links chain looks quite loose even with the chain puller in the last position (13).
Will be fitting 13/52 this weekend - that rear sprocket looks big! I'm hoping I still have 100kph capability for the roads but with the original 14/44 it always struggled to stay at 100kph in 6th so this migh give it the extra revs to stay there! Will post a pick when its up and running.
