Duplex Primary Drive Chain

[re5guy]

Morning everybody,

Does anybody know where I can purchase a new duplex primary drive chain? I've been searching in the UK without any luck. If it's got to be specially made, does anybody know where?

Afternoon Guy,

If there is a "Brammer" depot near you (used to be BSL) they should be able to get you some as they are agents for Reymolds Chain, I got a new triplex chain for my Triumph Bonneville from one of their depots. It helps if you take the old chain in.
I used a split link on my bonneville chain and have had no troube.
If you know someone witha trade account it could save you a lot of money.
I've added a link to their chain brochure.

Regards Stuart.

I would think its a standard metric HT chain that a enginering supplies company could get for you. I have use Bearings, Transmissions and Hydraullics ltd. in walsall wood .Brownhills.
They may help or point you in the rite direction.

Thanks for the replies, but still having difficulty in finding a supplier. I have even spoke to Reynolds UK direct, it's certainly not a standard duplex chain, it's a 3/8ths bush chain heavy duty, roller diameter 6.3mm and the centre line pitch of the sprocket teeth is 13mm, which means it doesn't fall in to the standard category chains.

Has anybody ever changed to a different type of chain, even if it meant changing the sprockets?

Afternoon Guy,

The .375 pitch 3/8ths is standard, the rollers at 6.3mm diameter are pretty close to 6.35 which is standard, what are you measuring to get 13mm.

I can't see suzuki specifying a completely different spec of chain for this bike.

Hi Stuart,

The 13mm is the transverse pitch of the chain. Spoke today with Andy at the chain man company, again, very knowledgable! This primary drive chain was made by a company called Subacki in Japan, who no longer manufacture this type of product, so basically, it's a special chain for the RE5. You can however purchase a mercedes chain but would have to carry out some machining work to the drive and driven sprockets.
This is a split bushed chain not a standard roller chain.

Thanks for all comments. Do hope this information is of some use, unless there is further information to be had.

What is a split bushed chain?

I remember Tsubaki chains well......if you google them they are still a large company and still making chains......you could do worse than send them an e mail?

Spoke with Tsubaki UK and they advised that they do not manufacture chain to this specification anymore.

In regards to it being a bush chain, it means that what you think of the rollers on a conventional chain, do not rotate and it's only the link pin that pivots.

My chain is well within service limits, and it's a good job too! Unless theres a nos chain out there somehwere!
