Good Tires for an '87 K100RS?

Looking for intel on what the good currently available tires are for an older K100RS with the narrower wheels. Am going to help a friend change his tires, so he can save a few bucks.

Tire sizes are (I think):

front 100/90-V 18 or 100/90-VR 18
rear 130/90-V 17 or 130/90-VR 17

This really cuts down the available selection and seems to limit construction to bias ply. Anyone have favorites in that subset of things? He's not a high mileage rider, nor is he a ricky roadracer type. Some 2-up but not super heavily loaded.

Isn't the rear a 130/80????
http://www.americanmototire.com/catalog/index.php has a provision to list the tire size and it will show you the tires in that size.

With that in mind, I ran Metzler ME880s on my '87 K100LT. The rear was a 140 in the ME880, but posed no problems. Tire life was really good at 11,000 + on the rear and I sold the bike. My research was the Metz Lazertec didn't last too long. A buddy put a set of Avon Roadriders on a R80RT and they handle great. Life?????

I ran Dunlop D205s on my '85 K100RS and my wife uses them on her K75S.

We'd get 10K+ miles out of a rear.

You do have to go up in size, but I had no problems mounting them.

I believe we used 110/80-18 and 140/80-17, I 'll look at the tires on her K75 tonight. My K100RS was sold 3-4 years ago.

Be careful in the first turn however, they will speed up the handling quite a bit compared to what was on there before.

I put some Bridgestone Spitfires on a K75S that I brought back to life. The buyer was in Sacramento so I rode it 1,200 miles down The Cascades to deliver it. Rode it to the point where were no chicken strips on the rear and found them to be more than up to the task.

I put some Dunlop 205s on my K1100LT. The bike would wander all over the lane at speed (to the point of being F'n scary) and they were off the bike in less than 1,000 miles.

Michelin Macadam 50s are pretty good tires for Ks - if they're still making them.

YMMV.

It's been several years but I liked the ME880s on the bike.

I tried a Dunlop once, I think it was the D205, not sure if they still make them. The handling wasn't as good as a sport bike tire but they lasted forever. And by forever, I mean I put several thousand miles on them and sold the bike to a guy that rode it to Alaska and back. He finally changed them because he was tired of looking at them.

Not very expensive either.

My wife and I ran these for years on our K100RSes. Great choice(s)

and in the rear...the Conti Tour

http://www.cruisercustomizing.com/co...TI-02480340000

I never like the 880...too hard. The Metzler Laser and Conti Tour seemed good in the wet, unaffected by rain grooves, and reasonably long lasting. And reasonably priced.

On my 87 K100rs I run the ME88 rear and the ME880 front. Tough to find alternatives and everything I have read says stay away from radials.

Where have you read this? I have radials on my K75 and it flippin' rocks! (Rode it up Hwy 1 last week.)

When I switched my K1100LT from bias ply to radials the handling MASSIVELY improved - especially in high speed sweepers.

I'm building a K100 now that will most definitely have radials on it.

The only caveat is that you need to run a 3 inch wide 3-spoke rear because I don't think there are any radials that will fit on the 2.75 in Y-spoke wheels.

Back when I had a K100RS, highs peed stable handling was very dependent on tire choice and wear.
Back then, the ME33 / 55 came with a heavier ply option that minimized weave.
Academic now, but that choice in 'race' compound gave the best handling and traction for very aggressive riding. I ended going to a Continuous sport tour rear as I can couldn't afford to replace the rear every month.

Given the parameters, the owner probably would be better served by a tire that isn't at either end of the race/tour spectrum. ME880s last a while but don't stick as well as softer compounds in low traction conditions. Maybe a Lasertec front and ME880 rear could work.

BT45s are a good, affordable choice based on usage on another bike, as are Pirelli Sport Demons (bit more expensive).
Lasertecs should also work well, but the mile/$ ratio could be a bit low.
Whichever, look for a higher silica content (Sport Demons) and tread for good rain traction.

All the above is FWIW and IMHO, tires have changed a fair bit in the last 6 years or so.
