:dunno
Hi all,

I've been reading your posts on tires with great intrest. I have a set of Metzeler M33 & M55's on my K100rt right now and they need to be changed. After reading your collective wisdom, I've decided to look for the 880's but can't seem to find the correct size for the rear anywhere. Any ideas of where to go? (be kind with the response, my wife tells me everyday where to go) I can find the front size but they are rated a H tire verses the stock V. Is that a big deal? Will other 17" sizes work? Web references would be very welcome.

Thanks in advance

BTW, I have a new rear brake rotor on the way. It seems to look alot like the slotted front one but the supplier (cyclebrakes.com) assure me it will work on the rear. There on sale right now.

I dunno what size you need, but Southwest Mototires (http://arizonamoto.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=SWMT&Category_Code=ME880) has THE best prices on tires, with free shipping if you buy two or more.

Ditto on SWMotoTires. These guys seem to want to compete too:

I've never tried 140X80X17 rear on the K100 bikes. The 100X80X18 should fit just fine up front. Your stock rear should be a 130X90X17 so there should be no problem going down one profile step and going up one width step. Swingarm clearance is your only question.
I run this combo on my K1100LT and love 'em!!!:clap

Thanks for the replys. :thumb

After a few days research, it appears the metzeler ME330 and 550's match up size wise to the OEM. They also are shown to be a little more into the sport riding area. I have 33 & 55's on the bike right now and this may be the best alternative for around the town and touring. Thoughts anyone? :dunno

I run an ME 880 up front and a Michelin Macadam 50 in 130/90-17 rear tire.
This combo seems to work well for me on a '85 BMW K100RT.

On cyclebrake's web site they are advertizing a rotor for $164.99. This is a front rotor. It will not fit the rear. Aside from the offset being wrong, the bolt pattern is also wrong with too small holes and lacking the two holes for the rotor screws.

:thumb Thanks Bruce, I didn't think it would work but was assured it would. Any ideas where to find one?

The BMW price list quotes the non-ABS rotor at just under $200.00. Chicago BMW offers 20% off all parts so that puts it around the same price that you would pay at cyclebrake. I would ask for a shipping cost quote though. Some dealers will match Chicago's prices.
To get prices go to Bob's BMW web site (download all of his pdf catalog) or Max BMW parts fiche.

85k100RT, I had the best mileage from an Avon touring tire on the rear with a Metzler Laser on the front on both a K100 and K100RT. I was very pleased with this combination for touring the slab. I seemed to get the best mileage from the Avon on the rear (18K) out of any other. I cant remember the Avon number but I do remember it is designated "Touring" and they guaranteed it for 15K mi. (if I remember correctly). The Metzler Laser (ME33) on the front was outstanding. The ME33 Laser got 30K (imagine that) Nuff said. This was my combination for the best mileage for tires and the pocketbook on my flying bricks. The only pitfall I noticed was the rubber compound on the Avon is hard. That needs to be taken into consideration when cruising in the rain and in the corners. You could also talk with Rob at Arizona Motorcycle Tires :type www.AZMCTIRES.com :brow From me to You, He would be able to give you the best opinion/advise on what tires to run for the type of riding you do (after all he sells all brands of tires for all types of bikes). I have been buying tires from him during Bike Week and Nationals since I can remember. Bottom Line (pun intended) be "anal" about checking the pressure in your tires (while they are cold). This will also help you obtain the best mileage out of your fun tickets and tires. Keep the rubber side down :thumb
