Hi Bob,
Zitat von "bobgass"
SO, my question is, does this shaking/buffeting/oscillating occur behind the fairing(s) of the K75 RT, K100LT, or K100RS for the average-sized rider?
I'm interested in all of your opinions, even as it may relate to the weather/climate/temperature where you live and ride.
Now, what is the average-sized rider? The one with the fat belly?
OK - I'm 190 cm for 95 kg and ride a K100LT in, say, "Central Europe" - link to more details in my signature.
On my previous full-fairing bike, a R100TIC (RT), the fairing provided excellent weather protection but caused a lot of buffeting at highway speeds.
On the K100LT, the upper part of the fairing is even better than on the R - almost no turbulences behind the fairing, and no buffeting (for the "but", see below). I have even observed that flies can stay on the gas tank at 80km/h ...
As far as I know, three different versions of the windshield were available from BMW:
* The "german" version, 430 mm, p/n 46632303660.
* Installed on my LT: The "non-german" version, 565 mm, p/n 46632303565.
* The version for "official vehicles", 625 mm, p/n 46632303608. I want to buy that one, one day ...
The 565-mm screen causes a lot of wind noise, since I receive a stream of air directly "in the the face". The big difference to the R-RT is that this is "just" noise - no turbulences, almost no buffeting (except behind trucks).
Weather protection: The protection for the rider's feet is less perfect on the K (compared to the R). The LT fairing is just perfect in cool/cold weather, less funny in summer ... even when I just ride for 10 km in summer, I'm drenched. No air. Legs will get very warm - it's not supportable in Jeans, so yet another good reason to ride ATGATT.
