I haven't had a chain bike for a long long time, but plan on an old model Africa twin or Transalp - what do long trippers do in terms of chain maintenance now?

I believe (from when I had a bike shop) that stiff links are the modern chains main enemy and therefor reason for needing maintenance or replacement, they also produce an annoying vibration on motorways as the stiff links pass the motor sprocket. This to me would imply that over and above lubrication some sort of cleaning to remove dirt and dust occasionally would keep things lasting as long as possible? I've heard of an old toothbrush and paraffin cleans without degreasing.

Would ALL long trippers use a scottoiler or similar as it may not always be possible to find aerosol chain lube (or chainsaw oil)?

Thanks for any incoming wisdom.

Start by going back, read this thread.
Start with my post from above:

Sounds like you've not ridden since the 60's ... when chains were removed for cleaning and dipped in Paraffin. Not how it's done now (hasn't been done this way since the advent of O ring chains in late 70's) We've now got X ring chains (DID chain) Game changing!

Vibration can come from a number of areas. Misalignment of chain, worn front sprocket (most common cause) or worn chain. Also, worn Cush Drive rubber dampers or even worn wheel/hubb bearings ... ALL can cause vibrations. Get everything right, put a bit of lube on your chain ... smooth!

The original Africa Twin used a 525 size O ring chain. This is a good thing ... 525 are very tough, long lasting chains ... but DO UPGRADE to a X ring chain. Buy the most expensive DID X ring you can find. Use quality OEM or JT sprockets.

Bring a spare front sprocket to be changed at 10K miles. This will extend chain life by 5K to 10K miles.

With even casual care, your new 525 X Ring chain/new sprockets will last over 20K miles ... or further. If riding in constant rain (UK) a Scott Oiler is a good idea. But do not use the Scott off road ... just makes a mess.

When on tour clean chain daily with WD40 or Kerosene. Just a quick one minute wipe down. (use your main stand) Easy. No fancy lubes required. In a pinch you can use 90W gear oil. Cheap and available worldwide. Excellent chain lube if a bit messy.

I use Dupont Teflon chain saver when close to home, but on the road, out of USA it's 90W for me. Done over 200K miles on X ring chains. Never a failure or problem. Use a RIVET link for master link, not clip type.

There is a TON of good knowledge on the Africa Twins. Use it to your advantage. No need to bring a spare chain on board, just a spare front sprocket. This should get you over 20K miles down the road. So plan for a complete change at that point.
