There once was a man called Matt Capri, and he was a speed merchant. From his, and other engineering workshops he contracted with, came mechanical objets d'art for Beemers of both the R & K variety. He made bikes go fast at exotic-sounding places like El Mirage in California. His ads, printed out in black & white, in club magazines and posted out to performance hungry Beemerphiles like myself, had me longing, nay, lusting for some of these tasty pieces of speed and performance-enhancing metal. Here are a few images for your perusal, all of them in some small way, now pieces of BMW recent-history.


In 1990 the complete four-into-one exhaust system would set you back the princely sum of US$450


For merely US$905 one could eliminate that "troublesome fuel injection" and change it out for some real, practical horsepower a man with tools could actually work on. (Tongue firmly planted in cheek).


US$1595 got you a 12.5:1 piston, 1138cc piston and sleeve kit.


Get cammed for US$695 a pair!


No rev limit, "up to 16 mph higher top speed", US$645...


What good is all of the added power if you reach the limits too soon? US$580 lets you spin it up even higher!


Breathe easier, US$79.95...

I'd like to get my hands on a few of these bits just for some fun. Imagine a warehouse or a closed up shop somewhere with a shelf full of dusty Luftmeister parts...

At one time I had a black ceramic coated Luftmeister 4-1. When I re-fitted a sidecar it would no longer fit with the subframe. I now wish I'd never sold it, irreplaceable.

It sounded horn.

Thanks for posting this stuff. Where'd you find it?

My turbo K75 has the mod'd cams and had (before I converted it to a paralever) the Lufty transmission gears too. I suspect that since it's a turbo it may also have the modded ICU as well.

My K100 has a Lufty exhaust.

Rummaging through some old catalogues I'd had stored away for the longterm, I discovered a Competition Accessories, spiral-bound folder with all manner of OEM and aftermarket flyers and brochures of BMW goodies on offer at the time. The 1990 BMW clothing and accessories catalogue is particularly funny, and brought back some fond and not-so memories for me. In it are slender Euro trash in ghastly red leather and/or textile riding gear, white boots, early system helmets and big hair for the ladies.

Here are some more tasty Lufty bits.

That ceramic-coated exhaler people still want, and pay top dollar for...


Turbo yer Mighty K. He got 'em going pretty fast for the day.




There's a company in So Cal still doing this mod, as discussed here on the forum in the recent past - can't locate the thread with a quick squiz, but it's here somewhere...


Before expert suspension makers WP were called WP they copped a heap of flack in some quarters over their (unfortunate, but likely not intended to cause offence) choice of company name.

My old bomb of a K-RS has no rev limiter, otherwise stock with K11 TBs, Motad exhaust, and 18" radial tyres. Could it be the PO, once a Beemer tech from the Brissy area, replaced the ICU with one of the above-mentioned ignition control units, or fiddled with it hisownself? It might help explain why I can spin it well past redline and it wants to keep on climbing to the moon. I've bounced the speedo needle off 255 k/ph (157 mph) a coupla times now - dialed in using Karamba software. Factor in for tyre diametre & inherent speedo error and that's got to be nudging low 150s, higher than a stock bike but about in the top speed territory Luftmeister claimed it could go.

FYI: That Karabma program isn't the greatest.

If your PC sound card doesn't put out enough amplitude (like on a netbook that has a weak sound card in order to save battery life) then it doesn't work right.

Also, some bikes (like the K1100LT and some K100s) have different final drive gear ratios so just selecting a model/tire sizes isn't adequate.

I find it's best to confirm a properly calibrated speedometer with a GPS.

The drive ratios don't affect the speed reading it comes directly from the wheel speed. I have found that my new laptop wont do the job like the old one.

Now you've gone and done it, made me feel like a dinosaur! I remember all that stuff. In fact, the rear suspension units still on my R100RS are Luftmeister bits.
I would like to point out that Matt didn't just disappear though. He became frustrated dealing with BMW (imagine!) and took up with Triumph. I kinda lost track of him for a while after that, but he did make the news some time back after being slapped with a huge fine for de-comissioning the air pollution equipment on bikes he was selling.
Matt was and is a real character. I found that when I went to his shop, service was remarkably better if I had my girl friend with me. Wink

1989, York, PA MOA national rally, hot, 9,000 attendees. I'd previously bought a chrome two-into-one Lufty pipe for my R90. The headers rattled in the collector. There was no clamp (and the taper prevented one) and no provision for tension springs. I lived with it for a month or so. I rang them a coupla times and got no response. Luftmeister were at the rally, selling. I waited my turn then enquired of Mr Capri concerning the fit of my new exhaust pipe. He listened for a brief moment then turned and grabbed a coupla springs off the table, saying, "weld some tabs onto the pipe for these."

He did a lot of R&D on the backs of his customers. You had to get used to that.
