Chain and Sprockets
 

Just wondering if anyone has found a particularly good supplier for these yet?
I want to drop one tooth on the back so I'm thinking of a call to B&C unless anyone has any other recommendations?

Here you go TT

One tooth less on the back is going to make it really high geared bigwink

Cheers Ricky, I looked on World's End and found their prices. B&C look cheaper for better quality sprockets at least.
Regarding the gearing, I did a quick search and found a good gearing calculator.
I input the values for primary and the separate gear ratios and then changed tyre size to suit and also tried the two different changes I wanted.
So, stock (15/45)-

-1T front (14/45)-

-1T rear (15/44)

You can see the rev range doesn't drop too badly, and I only get a theoretical +2mph top speed. What I actually hope for is a slightly more realistic speedo readout, and a happier feeling bike for the road work I do.

I have geared mine down, 1 tooth less on the front. It feels alot better more punch out of the bends and better cruising still at 80mph and my fuel comsumption is still in the 50s and that is riding quickly if you know what I mean, not to bothered about top speed.

Some interesting figures there. I notice that that the change up speed in 5th is 86mph as stock which would help explain the number of times I keep trying to change to a not-existant 6th gear :)

I suppose the ideal would be to drop 1 tooth at the front and have a 6th gear as overdrive on the motorway?

Yep I do that as well! I think -1T at the front and a 6 speed box would make the bike a heck of a lot better. Wonder if anyone has done a 6 speed swap from a Pegaso?

B&C are good value, just don't buy aluminum front or rear they will get chewed up faster than you can imagine. I still have the original rear on after 27K miles so it seems very good quality. So I would be the original Yam rear

B&C every time and they always seem to make nextday delivery.

The Tsubaki chain they supplied hasn't needed adjusting in 6000miles and both sprockets are still in good nick.

Unlike the pos original chain.

Would also make green laning at slower speeds more controlable for those of us less able than some. I too look for a sixth on occaisions. Had the same issues with my Africa Twin but that was older and I was supprised that the Ten only had five gears. Mind you I can live with it happily enough.

Hi Tom - if you've not bought one yet, I'd echo what Scottnet suggests and certainly go for steel rear teeth... You might want to consider a Supersprox rear (alloy centre and steel teeth) if you can get one for the stock Tenere hub (I think you can, it's the same PCD as a Yamaha Diversion as I recall) - I fitted one on the Tenere before the rally, rode all the way from Paris to Dakar with it (and with a dry chain), through all that sand and sh!t, and it still looks almost new! Worth the �45+ they now cost unfortunately...

I'd also recommend a DID XM chain - again, top quality and long life...

just bought a C&S kit from wemoto

IZUMI chain and sprocket kit with Heavy Duty O-ring chain, � 77.95

Hi JMo, not purchased as yet. I want to drop a tooth on the back, and although I've seen a supersprox rear for the Ten on the calsport site (from memory), I don't know if they come in less teeth. B&C told me that to go lower that 45T would be a special job, not a problem I've had them do special jobs for me in the past, but I don't know if supersprox would do them. I'll try a few leads on the divvy 600 though, to see what T they come in at. Nothing purchased yet, likely to be an after chrimble job.

Just a quikie, Jenny, did you mean VM chain, instead of XM?

Mmmmm, maybe... VM is the O-ring, XM is X-ring perhaps? I dunno, my brain is fudge at the moment...

I think it was the VM I got (used to use the boggo 520V, but they've stopped producing that I think...

Couldn't find any reference to XM anywhere, but the VM is an X ring. Will give that a shot then. Got a few more leads to chase up as to getting a 44T supersprox, if they don't work out then it's a Renthal for me.
Bought TBM today too, after CM had a pop at me for putting a free manual link up here I thought it was cheeky to just read the scans. Reads well, good work.

Ah sorry Tom - that was me being thick... I was getting confused with the X part... like you say, the VM is the X-ring, presumably the older 520V was/is the O-ring version then...

Renthal do a twin-ring rear sprocket (similar concept to the Supersprox), but not sure they have an XT660 PCD? A good cheap alternative is a regular Talon steel rear sprocket...

JMO, what did you use as front & rear sprocket for the H&L?
Thanks
Giampi

Hi Giampi - the front was a Renthal steel sprocket, the rear a Supersprox steel tooth/alloy body sprocket (similar to Renthal's Twinring), and a DID 520VM x-ring chain. I also took a plain steel Talon rear sprocket, but this didn't need to be used.

We ran all the bikes without lube the whole time (as it tends to increase wear in the sand), and both the teeth and chain lasted incredibly well... the chain is now orange and crusty of course, but not least because the bike spent three weeks on a ship - the sprockets themselves are still in surprisingly good shape.

Running the 18 inch rear wheel meant my gearing/chain length was significantly different to stock - for info, I was running 14/50 with a 114 link chain.
