I should be looking at an R100RS over the weekend. I have an 1100GS, but do not have any experience of the airheads. What are the most important things to check out. It has done less than 40K apparently.

Recommend you take someone who knows about Airheads and not the blonde type either.
It's good to have an objective point of view that will think cost to fix rather than easy to fix.
The first thing I would check for is crash damage.
Botched repairs
Receipts for maintenance etc
Is it complete and everything functioning.
What one are you going to view?

What to look out for all depends on what year the bike is.. You have three different variations of R100RS - pre 81, post 81 and the post 85 monos.

As you say it's pre 1981 and you have no experience of airheads be warned the "brakes" will terrify you.


I have a 1991 XTZ660. Dodgy brakes will not surprise me![]()

Here's a strange suggestion for you; when sitting on the bike see if your knees catch on the edge of the fairing. Mine do, and I wasn't keen.

On a test ride, Do not, repeat Do Not try to change gear quickly.
The correct procedure is Clutch in count 123 and move lever changing up,
Changing down = Clutch, 123 accompanied with a quick blip of throttle when moving lever.....
I've seen many a white face on those who change down without blipping
Locks the back wheel quicker than any airhead brakes do![]()
