85 Bmw K100 Rt.

I'm interested in getting one of these for a long distance tourer. What are the Pros and cons? Should I get a later model?


Yes I did look through a lot of threads using the search function. Figure this would make it a little easier for those that are interested.

I had a 1987 BMW K100 RT from 2001 through 2006. I thought it was a great bike. I sold it to buy a 2003 1150GS only because of all the ranch roads out here in Oklahoma City. The K bike is very good for the touring mission. Maintenance is minimal and it never left me on the side of the road. I have found BMW owners usually take care of their bikes and garage them.

During the summer the heat builds up behind the fairing and can be a bit much. I used to move my knees out into the slipstream to cool down. In fall and winter that's a great feature. For the money...mine was $3500 from a dealer it's a good buy.

Another issue with early K's are noisy brakes. The only thing I found to quite them down was Mercedes brake grease. The brakes are flawless but they do talk to you.

All in all I miss by K bike, The big GS and I are still dating but I will fall in love with her. By the way don't crank the bike on a low battery charge...you will blow the starter relay...found out the hard way. I'm not the only one....the dealer had them in stock.

I put a power plug on the bike to use a battery charger. Parts are no problem and there is a whole sub culture out there, just do a google search.

If I had the money I may look at early 90's K1100, but if you have one in sight I wouldn't hesitate. One more thing....I may have bought a K100 RS if I had to do it over again. If the bike is a straight tour bike fine....if it's a daily driver or weekend tour bike the RS may be a better choice.

Again lots of info out there. Hope this helps

This one is going to be purely for cold weather and long distance rides.

I've got my eyes on an '85. What should I look out for? Wasn't there something special about that year?

There was lots "special" about that year.

It was the first USA year for the K-bike and there was lots left to do to perfiect this bike.

Muffler falls apart
Fuel boils, i.e. vapor lock
Incredible heat on rider
Intolerable vibration in hand grips (see muffler falls apart)

It was the first and last K-bike I ever considered.

It's not surprising they're cheaper on the used market than Airheads the same or even a couple years older.

I understand, however they were improved over time, as is to be expected from BMW. I'd look for a 16V over an 8V.

I had an '85 K100RT. The bike had heat issues. Namely, on warm days the heat buildup behind the windshield was quite bothersome. On hot days, it was almost unbearable, with persipiration dripping down inside my helmet. I did have a tall windshield on the bike, though.

Ugh. Just thinking about roasting on that bike makes me sweat.

Other than that, and a nagging issue with a poor electrical connection (eventually solved) it was a solid, reliable bike that rode well.

I traded it for a ZX-11 in 1990 and speed's been the game ever since.

Wasn't the 16v only in the RS?

I believe the early 90's were all 16 valve. The first K's were 8 valve. I kind of agree with the other poster....later is better. Having said that it really depends on how much you want to spend and want you want.

As far as the buzzing goes the early k's were buzzy. That's why the K75 were so successful. They were 3 cylinders and had a counter balancer. The 100's did not. My bike had aftermarket foam grips so the buzz didn't bother me.

If you ride loooong distance think about heated grips. I have heated grips on my GS and they extended your time in cooler temps.

If you get a good deal on the 85 your looking at you wont be sorry, the bike will serve you well. By the way in 2001 on my 87 I paid $3500 with 32,000 miles, repainted the fairing (it was used hard), took care of it, replaced a bent rim (that I bent), battery, and when I traded it in the dealer sold it for $4000- $4500 (don't know for sure, but he gave he $2300 on trade in).

What i liked about the K bike was for 1985 it was fuel injected, electronic ignition, shaft, water cooled, double disk front brakes, etc...pretty good for mid 80's.

Yeah. I'm looking for a budget machine. I don't really want to spend more than $3500.

I just read the link from the other poster and it's good advice...I read that when I had my K bike. The advise is good because people who owned the K bike rode the shit out of them.

On a 22 year old bike the rubber will need work.....I lubed my rear spline and it was fine.....I think BMW said to do it every 10,000 miles. I also remember the issue with the speedo....I think they used plastic gears...but the speedos were an issue. My gas gauge was not accurate....but it was inaccurate within a 10th of a gallon all the time. I could be 150 miles before my low fuel light came on.

Bottom line.....I've heard about a lot of K bikes getting over 100,000 miles, of course so did R bikes. The reason I ride BMW is they make good stuff. When I bought the K bike I was looking at the Kawasaki Concours (My brother rode one for 41,000 miles). The BMW just had a soul.....the Connie was great but.....just.....mechanical?? Best way to describe it.

My car is my car...my bike is ME.

I'm not afraid to use a wrench. Matter of fact, I want to have to put a little work into it. Otherwise I'd look at a newer japanese machine.

I rode a K100RT for a season in the middle of a bunch of seasons with airheads. I think if I'd bought a K100RS I'd prolly still have it.

Pros:
Killer reliable motor with more than enough power for anything you want to do on a public road. These things are bomb-proof. The vibes never bothered me.

Not a bad chassis, either. With sorted suspension they track pretty well for a full on touring bike.

Fairing works great in cooler weather. Good wx protection and reasonably aerodynamic for high speed running etc.

Between the motor and the fairing you can devour HUGE miles of highway with minimal effort.

Cons:
As noted, the fairing will roast you alive in hot weather. This is NOT an understatement.

The stock seat will completely emasculate you. On a really hot day the fairing/seat one-two combination will make you wish for an airhead.

Stock suspension is pretty poor. They cry out for a good quality shock to improve handling and rideablity. Tuning the fork with quality springs is a good idea, too. In stock form it's horribly undersrpung.

In Conclusion:
A solid machine that's worth sorting for long term high mile use. But it WILL need sorting (works shock, Corbin seat etc) for long term usefulness. A real bargain, too, imho. (my buddies old K75 with 250k kms still rides better than his Oilhead RS).

Fit, finish, build quality etc are miles ahead of a Kawasaki Concours. My nieghbor just got rid of one of those and I really couldn't believe just how shoddy the thing was.

fwiw,

I found one with 54k miles and they only want $2500. Makes me wonder what might be wrong with it. They're not responding to my emails so I think I'm going to give them a call.

They're only 8 hours away from me.


Thanks for the ad. That guys a lot closer to me. I'll check that one out as well.
