15/47
 

Probably got this in the wrong place !! but hey ho!!

The standard set up for sprockets on the XTZ is 15/45 , please tell me if i'm wrong
But after my last trip to Maroc the 520 chain last 2 mins and i found 45 just a little clutch needy.......................ok i ride like a nutter !!!
My thoughts are a 525 / 15 / 47 set up .....�160 from "OFF THE ROAD" as i want a bit of a compermise off and on for my Balkan trip

So to my Question ....Will the 47 make much differance ?????

Cheers Phil

I had 15/45 in Maroc as well, works fine until you follow Keith up some singletrack where only goats go :toothy9:

I'm running 14/45 now for green laning and short trips and really like it. Bike will finally powerslide in third lol.

I will be soon getting 525 chain and 16/47 for the long haul to Turkey where I will swap to 15/47 for trail work.

So to answer your question ... I don't know:icon_mrgreen:

Hi , sorry can't remember your namebut we rode together for a while in Maroc .....small ugly ****** on a black tenere :laughing5:

A (long) while back I did a comparison of gearing

For what it's worth I ended up going 15/46 as I found the 14 too low for everyday use.

Just finished the 3rd chain and sprocket set in 38k miles which was 15/46 with a Renthal hard anodised alloy rear. Lasted 9k. Chain was Tsubaki O-ring 520, better than OE but not as good as the previous set up which was Supersprox rear with DID VXM chain, lasted 19k miles.
OE chain was the worst for wear.

I like to say thanks Tom, but those charts blew my head up !!!

I've gone for 15:47 : 525 chain set up , i've got a DR650 that i push to the limits and that has a 525 set up and the chain last 3 x longer

We'll see and i'll let you all know :newspaper:

Hello Phil,
I'm Tomasz (blue Tenere)

I should be in Turkey in July, only have 2 weeks there so probably won't get as far as Georgia. I would love to do some of the Transanatolia Rally route if I can find enough info ... Have you got any gpx data already by chance?

Chain Length
 

Hi,

i tried installing a 47 rear sprocket with the original 15 front sprocket and chain. And guess what: The 110 chain was too short. 8o)
Any advise if a 112 will fit, or do i need a 114?
And what if i also change to a 14 front sprocket?

Thanks,
Ralf

I use 15/48.. but I feel 15/50 would be a good set up..
Not being able to find 50 tooth rear sprockets I will go with
14/48.. gives 4500rpm @ 100kph , 500 revs above standard gearing...
I always buy 120 link chains... shorten them as required..

Hey Petenz
Is that 4500rpm when your speedo reads 100kph? Or is that with GPS?
Cheers

As the gearing change will screw the speedo up... it would be GPS
The bike will be traveling forward at 100kph & motor doing 4500rpm
in 5th gear..

Anyone know where I can get an aftermarket 14 tooth front for a z in aus? Thanks

Sorry Tomasz
completly missed your post and don't have any GPX stuff i'm just heading for the hills and see where i end up !!!

On my z I tried a 14 front sprocket with oem 45 rear. Gearing felt great for fast dirt roads, was much better for tight work and was borderline acceptable for hwy runs.
Time for a new set so bought 15/48 525 set which I thought would be same as 14/45. The 15/48 is actually slightly lower geared than 14/45.
So now am wondering if anyone knows if a 112 link chain will fit 16/48 combo?

Thanks SiKa but the calculator is telling me 118 links which is incorrect.
Anyone else use 16/48 and know how many links you have?

One or two extra links will do the job, but that is entirely dependent on whereabouts you're axle is currently sitting in the slot in the swing arm with your current setup. If it's in the middle of the adjustment range, then one link may well do. If it's right at the back (unlikely) then you might get away with the chain you've got. If it's up in the first half then two links are probably necessary. Just make sure you need to leave yourself enough room for future adjustment.

It's also worth noting that the difference between the rear axle being at the front and the back of the adjustment slot has a surprisingly significant effect on the overall geometry and handling of a motorcycle. Ideally you want to be somewhere in the middle.

16/48 will give you exactly the same final drive ratio (1:3) as stock 15/45 - is that want you want to achieve?

You might be better off sticking with the chain you've got and biting the bullet and getting a 47T rear, which will give you slightly lower gearing the stock, but not as low as 14/45. Buy the time you've bought the extra chain links and a new front sprocket, a new rear sprocket isn't going to work out any dearer? Be easier job too?

I don't know for sure (never heard of anyone using 16/48), but problems may arise with a 16/48 setup due to the fact the upper and lower runs of the chain will be quite a bit further apart from each other compared with stock. This could pose issues with the chain running heavily (and for longer) on the upper and lower tensioner rollers at full compression and full extension of the rear shock. As a minimum it would be worth changing the fixed OE rollers for poly versions with a proper roller bearing.

Thanks Pleiades for your response. Good point about the chain being a lot further apart with 16/48. The reason I'm asking is I've just fitted 15/48 and am about to go on a run mainly open tar roads. With 15/48 @ 100k's according to GPS revs are 4500. My actual speedo reads 118kph. Thought a quick cheaper way to give longer legs would be wack a 16 on. Love the 15/48 for open and tightest dirt. A 46 is probably what I should get.
Thanks for helping chew the fat on this subject.
