Relatively level superslab, rider and tank bag only, Avg speed close to 70 mph (w/out the occasional run up to the ton for kicks) gives me mileage between 46-48. On a very good day, I'll get to 50. Loaded with gear, avg speed closer to 80 mph (with the occasional speed rush), I slide down towards 42-44. Around town, commuting, riding the twisties, or any other time I give my wrist a workout, I hover between 37-40, with dips as low as 35. Oh yes, it does tend to get better mileage after being serviced, and worse mileage if I neglect it.

Would be nice for in town but terrible at 60 mph. Question: What can be done to get good wind protection on the K75. Still looking for a K75. gerry barton Parabellum Scout. It will put the airflow at about the top of your helmet. Also, air will hit the shoulders. Sounds like you are looking at a "C". I have one which I installed a Scout. Much warmer in cool weather, Adequate airflow to keep cool when hot. You will need the optional turn signals if it is the C since they are integral with the C fairing.

(i am 6 feet, 0 inches). it just seems to be the perfect balance. of course, if its very cold, you will be cold. if its very hot, you will be hot. but there is a lot of room in between. the windshield was designed to be bolted on(i assume you are talking about a k75c in your posting) so adding it should be no problem. it may be a bit pricey from a dealer, but you might be able to get one used. on the other hand, maybe you just want to buy a k75t. i have enjoyed mine for years.

I know it will require a spacer between the wheel and the drive unit, but CC products says the spacer doesn't affect handling. I guess the main thing would be the bolt pattern? Thanks for any input! ==== The front is problematical; the rear straightforward. The front has an entirely different mounting arrangement and will require almost a complete graft of the newer forks so as to allow the new brakes, etc, etc, etc. You get the picture: $$$!!! The rear is easier, but problems persist. Here's what I had to do to mount a 4.5" wide KRS wheel on my K75S: 1. Bought a bend wheel and trued it out myself. 2. The KRS wheel is offset .375" to the left of a normal early K wheel. I had a machinist remove .250" of material off of the mounting face which centered the wheel nicely in the swingarm. 3. Then, with the material removed, I had to shorten new lug bolts also by .250" and thread them .250" deeper along the shank. I also installed the center (5th) lug bolt just to be sure! 4. Finally, the centerstand needs to be modified to clear the wider tire. I removed the stand and brought it to a friend who has an acetylene torch. We heated up the left leg and did a series of bends that allowed enough tire clearance. That was it! I mounted Sportmax's front and rear (110/80-18 and 150/70-18) the first time. I later mounted bias ply BT35 Battlax's (100/80-18 and 140/70-18) which worked VERY well and performed much better than the radials. It really IS true that bikes designed for bias ply or radials really should not be mounted with the opposite construction! regards, Rob Lentini Tucson, AZ (520) 790-8865 (H), (520) 295-6411 (B) '94 R 1100 RS Three Flags 97 #205 MSF, BMWMOA, BMWRA, IOC, AMA BMWMOA Board Member "Elect" "LET'S RIDE MORE AND POLITIC LESS" From ibmwrNoSpam@NoSpamworld.std.com Sun Jul 6 18:25:45 1997 Date: Wed, 22 Jan 1997 20:03:16 To: bmwmcNoSpam@NoSpamworld.std.com From: dbyker Subject: Re: BMW: K75s windscreen buffeting fix?

Your >comments/experiences are welcome. >Tom Maszerowski (tommaszNoSpam@NoSpammacconnect.com) As a 5'11" former K75S rider, I may have some bad news for you. I loved my K75S, except for the wind noise at my helmet level. I tried stock fairing, stock fairing with Saeng edging, Aeroflow windscreen, Aeroflow with Saeng edging, different helmets and different ear plugs. Everything I tried quieted the wind noise down, but nothing made that bike remotely 'quiet'. After 14,000 miles, I traded it in for a K75RT. The RT is still not 'silent', but it is much quieter, and I can usually get a combination of earplugs, helmet, face shield, and adjustable windscreen height to make the noise level acceptable - something I finally came to accept I was never going to do with my K75S. If you're 6'4", I don't know how you've taken the noise this long - you may even have some permanent hearing damage, depending how long you've ridden that bike. I don't mean to disparage a fine motorcycle (the K75S), but for some people, including me, it will never be an acceptable bike to live with because of the wind noise. This is a pity, because otherwise it's a really nice bike. In my opinion, you're best bet, if you want to keep your K75S, with your height, is to look into a Parabellum windscreen system. It will detract from the appearance of your bike, but it might quiet the wind noise on your bike enough for you so you can continue to ride it. If that doesn't work, your only other options might be to remove the S fairing completely (not simple, but a 'clean' bike generates less noise at the helmet level, I believe), put a Pichler or similar aftermarket fairing on it, or trade it for something else (expensive, but perhaps the best solution). Because I've been there, I sincerely hope this helps. Good luck.

I rode a K75S for 9 years. They're quite different from airheads, some find them too appliance like, but I liked the smooth mechanical presentation. The C means the bike comes with a small, fork-mounted fairing. Mechanically, it is the same as any other K75 machine, although the S models had a siffer front fork with a bit less travel; the stiffer fork was incorporated into all K bikes around 1991. Mechanical problems are possible, but unlikely. Ham-footed shifting can wear the shift drum, which is aluminum. On the K75 bikes, there is a spring which provides tension between two gears on the intermediate shaft. If this spring gets soft, the motor will buzz at lower rpms. This is moderately common; the motor will run happily anyway. Finally, the two sets of splines at the driveshaft will wear (expensively) if they're not lubricated. If you don't know the bike's history, you might consider pulling the rear drive, withdrawing the driveshaft, and inspecting the splines at both ends. There ought to be some lubricant, and the splines themselves ought not look worn. It is quite common for the bikes to go well over 100K with no significant difficulties. __________________________________________________________________________ David Brick Santa Cruz CA dbrickNoSpam@NoSpamarmory.com 96 BMW R11RSL RA MOA BOOF etc Date: Tue, 28 Oct 1997 07:46:57 -0500 (EST) From: RKMorrowNoSpam@NoSpamaol.com Subject: Re: BMW: K75RT storage compartment under seat > Fellow Presidents, > I recently purchased a '94 K75RT and their was not a storage > compartment under the seat. However, a friend of mine who has Do you have ABS? If so, look in the cubby behind the dual seat for a silver box an inch or two deep. On the police version of the K75 (which has a solo seat) the ABS computer is mounted above the fuel injection computer, which in turn is above the battery. Do you have a converted police bike? Or did BMW put the ABS unit here on some ordinary production models? - -Bob
