Bmw r80/90/100

Not replaced but inspected. It is easy to get to as it is on front of the engine. This is a good site is you want exploded diagrams. For a bike to do mechanics on it is one of the easiest as everthing generally is exposed.

Reason I asked was the R60 I had reached about 75k IIRC when I replaced the timing chain (simplex) and sprockets, the difference in performance was staggering and brought my fuel averages back up from around 44-46 mpg to 50-52 mpg

I get about 45mpg but that is London riding and ragging it on the A2 doing 80-90 so can complain. Only up to 52k so just run in.

Theres a R100S lying at my work, unused since 1983.. its got 1071 miles on the clock... owner thinks its worth a fortune, but it needs a lot of work.

Recommisioned it is worth 2.5-3k. On the other hand you might find an avid idiot collector who will pay what "he" thinks it is worth. At best it is a realy nice R80 thats it. They are not exactly collectable. They are a good usable long lived bike but then so are many other models, so what makes him think it is worth a fortune? I have seen others in better nick with 50-60k on the clock which still fetch 1.5-2k. A bike is only worth what folks are willing to pay and an R80 is still an R80 plenty around so a lot of choice. Just my opinion of course.

shame you didn't get the urge earlier. sold off a r100rs for £800

starters are a weak point on this engine. luckily the earlier (heavier) bosch units are a relatively simple retro fit.

seals on the fuel filler

soft, flexible suspension and an interesting amount of shaft reaction.

i found the ergos of the RS to be very strange tbh, but the guy who owned it previously rode 2 up to Southern Spain in 3 days..........but i don't think he knew any better

that's waay more than mine went for on ebays and that looks like a much bigger screen - which I would have liked, the screen on mine gave wind blast right in the visor, so much I had to get a new lid!

I ran an old R90S up and down to work for the best part of ten years until some collector offered me silly money for it. Lovely old bikes,but not everyone's cup of tea,you need to be prepared to fit with the bike's way of going rather than make it something it can never be.

Only bike I ever owned that almost trebled it's value and yet I did nothing more than get a few stone chips on the bikini fairing touched up. Dead easy to work on,not that I had to do much of that. Pushrod seals was about the extent of spannering required.

This was mine.

Irony, the R90S is collectabe you aren't yet both have aged. Of course the R90 can still "Go" whilst the Skubbers is more last of the summer wine. The R90 is collectable Skubbers is objectionable the R90 has some class, but Skubbers has a big ass. 20 years on and Skub bemoans his loss, but the R90S has kept its gloss.
So if you can buy one under a grand your wallet a loss will not withstand.

I ran an R65 and an R100 as a courier in Glasgow and loved them to bits although the particular 65 had atrocious electrics and would frequently die a death at night at 80 in the outside lane of the M74 till some fiddling under the seat would kick it back into life again. The old carbs were easy to clean out with the tray on the bottom

Cracking bike and would keep on running despite little faults like one of the cylinders sitting a couple of degrees up after being slung along the road, no rear brake and a shaft drive that ran dry due to a leaky seal and lazy owner............. still put 30,000 miles on it in a few months

I borrowed an R65 for about 6 months in the '80s the thing had a terrible vibration in top gear from just below 70 to about 85, murdered my nuts with the buzzing.

Having just come from a tuned RD250LC it felt silky smooth to me

I've had a couple, first one was an ex-cop R80RT twin shock jobby, needed carb diaphragms at a fiver each, sold it on then the wiring inside the headlamp caught fire.

2nd was a mono R80 with an R100R engine in it, stolen from a tourist in Dublin, wrecked and I bought the wreckage from the salvage folk, ended up putting a new shock on it and a proper top yoke, ran it with an S fairing and RS bars, then an aftermarket GPz1100 twin light jobby, then it ended up a gloss white RT.

Always seemed to need something done too it, had to replace the loom, flasher relay, LHS switchgear, couple of clutch cables, and for some reason the arm for the rear drum brake crumbled away one day.





I'd probably buy another, the 800 certainly was a smoother bike, even if it wasn't the fastest thing in the world.

Well I've finally gone and done it!

I've bought an 1981 R80rt, ex plod apparantly. its an already started project from another forum. it came with a Norton Tank and a Ducati style tail end.. which may or may not get used.

Prior to losing the bodywork the engine did run (allegedly) but I'd like to strip it all and have a rebuild anyway..

I'm planning on making it a Cafe Racer.. I'll keep you posted.


why has the sodding pic gone small? Bahh
