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?

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)-

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...
