Rear Sprocket
 

Hi Kev (or anyone listening),

I am trying to purchase a JT rear sprocket (45tooth) and the suppliers have nil in stock with no idea when one would arrive (as per the bike shop). Does anyone know if there is one sitting around in stock somewhere or what is the best to replace it with (of the same quality or better), its to go with a JT front and a RK GB520GXW chain.

Thanks

Paul

Hello Paul, I use a 46 (for x wheel) + 48 (for r wheel) Supersprox. It's a lightweight, durable, gold coloured very good sprocket and not to expensive.

Supersprox all the time.

Steel teeth and ali body makes it a real good all -rounder that will last 3+ years on your XT.

ONly sprocket i would use.

The only other alternative is to go to Off the road.de and buy a 45t steel replacement sprocket, but for what you will pay for this and the time it will take to send it i'd go on the Supersprox website and see where your local dealer is...

Have a look as there may be a dealer/supplier in AUS

Paul JT sprocket are great I have used them for years.

I have in Kev's stock a brand new JT 47T rear sprocket or a almost new JT 46T that did 20kms to work & back before fitting a 48T. I perfer the quite throttle responce that the 46/48 sprockets offer. They also give less surging at traffic speeds.

The 46T will fit on a standard chain, the 47T will need one link longer then standard.

Let me know if you want one, I can post one off to you tomorrow.

47T $30.00 + postage.
46T $25.00 + postage.
Postage should be around the $12/15.

Thanks for the help Kev,
I've been running a 46 for the last 20,000Km witch was put on at the same time as the PCIII. As most of my commuting is at 80 - 100km/h (plus that little extra that's needed to keep up with the traffic) I would like to drop the revs a touch, I find that the surging is minimal (for a single) and dont think dropping back a tooth will make much difference to the surging.

You have obviously tried a variety of combinations and if you have a better idea, I'm listening.

Regards

Paul

I have tried, 15/45, 15/46, 15/47, 15/48, 16/45, 16/46.
I would try 16/46, that will give you a better cruise speed. I found 16/45 to tall for me, great if you want to cruise at 130/140KPH.

You can buy 16T in Oz.

Let me know what ratio you would like & I can check stock in Brisbane for you.

Hey Kev

Is that 46t still available?? will send paypal payment tonight if it is!

The standard is 15/45 correct?? and just to make sure i know what i am on about, if i go up one on the back i will have a bit more bang in each gear but have a less top speed, is that correct?

Gone awhile back, still got a brand new 47T if you want it $35.00 posted, they cost $50.00 new from the shop. 47T will not fit the standard chain, if you are doing new chain & sprockets then you will be ok with the 47T, as you can cut the chain to suite.

damn, got a new chain and sprocket about 5months ago, might find somewhere online to order the 46T, does it change much when you go from 15/45T to 15/46T kev?

Not much, I like the 46T rear for riding below 100KPH over that the 45T is better.

kev, or anyone, do u know somewhere i can order JT sprockets online from?

finding it really hard to find an online store to order a 46T sprocket from, and supersprox want $80 for their sprockets, thats a bit expensive i think!!

any links to stores to order from would be greatly appreciated, postage to Aus is also needed

Cheers

Sorry I don't. I order mine through my local Yamaha Dealer.

I used JTs on my original wheelset, and they are great value - however, I would certainly say it is worth paying the extra for a Supersprox if you can afford it - I fitted one on the rally bike, and rode it from Paris to Dakar (that was 8000kms) without any lube, and it still looks almost new...

I've since changed the front (JT) sprocket and chain as the chain was rusty once the bike came off the ship, but am going to stick with the Supersprox on the rear until it eventually wears out!

btw. I can recommend DID 520 VM X-ring chains, again - I used only one on the rally (no lube) and it showed little sign of stretching... it would still be on there if it wasn't covered in barnacles!

Those SuperSprox look good.. but $105 shipped to Aus, that's a bit expensive for a rear sprocket!

Might need to call the local yam dealer and see how much the JT sprockets are. Would think, or hope, they would be half or less than a supersprox...

Rear JT sprocket = AUD$55.00

Just fitted a JT 15T front sprocket and a JT 46T rear sprocket with a 520GXW chain and its really brought the bike to life. Also replaced the cush drive which was rooted. Now just need Kev to go on holidays so he can do the fuel mod and the stage 3 cold air intake.

Cheers Griz

The 46T does make the XT more fun to ride. The stage 3 airbox is the way to go.

I still have a brand new JT 47T rear if anyone is looking for one.

Did you go from a 45T to the 46T? I was thinking 47T but don't want to buy a new chain for that, so I was wondering if one tooth on the rear sprocket really feels any different?

It sure does.

Right, and the wheel would move forward in the swing arm which should also make it a bit more wheelie:ish.

A 46T will fit straight in.

Go 14/50 and hoist a minger in every gear!

15/44 for mine..
 

15/ 44 = Love it.. Top speed junky.. Cruise speed 140-150 with more on tap..
Still works great on single trails and nasty forestry hills.
Personal preference really.
Also makes first gear taller for roll on wheelies ( no clutch) from slow start..

My DR-Z has silly gearing (14:49) on it for enduros (proper walking pace first gear, useful when you're trying to thread a comparitively heavy bike through a tight woods section), which I thought would make it a wheelie monster with the supermoto wheels on it. It actually made it harder to wheelie than when it was on 14:41, because the gears are now so short it runs out of revs before the forks extend fully, let alone the front wheel lifts.

It is hilarious though - you can pull away in 5th with a bit of clutch abuse, and you just ride it like a twist-and-go once it's moving :D

Quoting myself here, I can just say that I have now changed from 15-45 into 15-46 and it was a really good improvement. Some extra punch and better suited to swedish speed limits, and 100km/h + is still working fine for highways. Can be recommended. For me it feels like the optimum compromise.

Oh, the bike did feel just a little bit less stable, since the rear wheel moved forward 1-1.5cm, but the bike is already so stable so it isn't really a problem.

Guys im looking to do a trip to Italy from the UK and wanted to up the gearing a little. Its been suggested to drop 3 teeth on the rear to get a good 80mph motorway cruise. I like the sound of this as i don't "race" my XTX.
Whats on the front and rear as standard, how many teeth on each?
