I was just looking at the new 3 series. They have bolted on a turbo and are getting over 300 HP. The tester says there is no turbo lag at all. I wonder if BMW has ever thought of adding a turbo to the LT? To my way of thinking, the biggest negative of turbocharging in the past, was the lag. I remember counting to three when I used to boot my old Saab 9-5 before the boost would kick in. Now that technology has pretty much eliminated the problem, you would think that this could be an inexpensive fix for the LT. More horsepower without the huge costs of retooling a new engine. A turbo plus a few minor upgrades might be all this bike needs to push its date for a major retrofit out another 3 or 4 more years. I know it would get my attention.

It has been done, at least once. This website has been around for years, but in spite of the great sounding sales pitch, and all the pictures, I am not aware of anyone ever taking them up on one. I am sure if anyone had purchased one of the kits, we would have heard about it.

Hi, Ron. You might take a look at this site from our own Accessories Section listing: http://www.rbracing-rsr.com/bmwturbos.htm#k1200. These folks took a look at turbo charging the LT back in 2003 and haven't updated the web site since by what I see. They agree with most folks here, myself included, that the weak link on the LT drive train is the clutch. It's real easy to majorly slip the clutch without go quicker mods. Some folks made mention sometime ago about roasting the clutch trying to pull hole-shots on the LT and one guy (LTCAMPER?) even went so far as to put a two pressure plate spring setup in his LT. Didn't work as it ate the friction disk and the clutch hydraulic slave cylinder failed pushing the extra heavy clutch springs.

Could you turbo the LT? Yeah, according to the website, RBRACING-RSR did it and the pictures look plenty sexy. Bet it costs like chemotherapy and you can't get in the boost untill the clutch has hooked-up and even then, if the turbo is blowing hard you could get the clutch disc to start slipping.

This actually reminds me of this story:
Jet Assisted Take-Off

1995 Darwin Awards Winner
Confirmed Bogus by Darwin



The Arizona Highway Patrol were mystified when they came upon a pile of smoldering wreckage embedded in the side of a cliff rising above the road at the apex of a curve. The metal debris resembled the site of an airplane crash, but it turned out to be the vaporized remains of an automobile. The make of the vehicle was unidentifiable at the scene.

The folks in the lab finally figured out what it was, and pieced together the events that led up to its demise.

It seems that a former Air Force sergeant had somehow got hold of a JATO (Jet Assisted Take-Off) unit. JATO units are solid fuel rockets used to give heavy military transport airplanes an extra push for take-off from short airfields.

Dried desert lakebeds are the location of choice for breaking the world ground vehicle speed record. The sergeant took the JATO unit into the Arizona desert and found a long, straight stretch of road. He attached the JATO unit to his car, jumped in, accelerated to a high speed, and fired off the rocket.

The facts, as best as could be determined, are as follows:

The operator was driving a 1967 Chevy Impala. He ignited the JATO unit approximately 3.9 miles from the crash site. This was established by the location of a prominently scorched and melted strip of asphalt. The vehicle quickly reached a speed of between 250 and 300 mph and continued at that speed, under full power, for an additional 20-25 seconds. The soon-to-be pilot experienced G-forces usually reserved for dog-fighting F-14 jocks under full afterburners.

The Chevy remained on the straight highway for approximately 2.6 miles (15-20 seconds) before the driver applied the brakes, completely melting them, blowing the tires, and leaving thick rubber marks on the road surface. The vehicle then became airborne for an additional 1.3 miles, impacted the cliff face at a height of 125 feet, and left a blackened crater 3 feet deep in the rock.



Most of the driver's remains were not recovered; however, small fragments of bone, teeth, and hair were extracted from the crater, and fingernail and bone shards were removed from a piece of debris believed to be a portion of the steering wheel.
Ironically a still-legible bumper sticker was found, reading

"How do you like my driving? Dial 1-800-EAT-SHIT."

So... anyone still wants a turbo on their LT???:D :rotf:

When I ask about turbo charging the Lt's engine, I wasn't thinking about some cheesy home built after market job, but a full blown factory effort by the company. You have to think that with the cost of retooling the LT's engine, that a factory turbo might be just what this bike needs to keep it fresh and current for another couple of years before they replace it with a new model. If BMW can adapt a turbo to the three series car, why wouldn't it work on this bike?

Oh, let's not go there. 2008 is far enough away already.

You need to use a little "systems thinking" here. If you simply increase the horsepower of the engine, what effect will that have on the other components of the "system" (motorcycle)?

I think the motorcycle industry in general still remembers the factory turbos from the eighties and how unreliable they were... Of course, maybe now we have the technology to rebuild it, better than it was before. Better ... stronger ... faster. :D

I remember reading somewhere that Peugeot has come out with a full-production supercharged scooter. They claim the advantages are two-fold: more power, and better gas economy. So maybe that's another option that we may see more of in the future?

(EDIT) Found a link to Peugeot's scooter:

I would like for those german engineers to fix what we already have before they create more $hit! I would not buy it; in fact I will not buy another BMW until they get their heads out of their a$$ and at least try to fix some of this stuff. I'm tired of fixing their fudge ups. Besides there is no need to retool, they have the GT engine.

Hmmm, let's see.

Once they figure out:

1) The inadequate load rating of the tires

2) The front end wobble (thought his was fixed with the 05's...:rolleyes: )

3) The HORRIBLE seats - although common to all motorcycles ;)

4) The miserable shocks

5) The really stupid clutch issue that requires a little "drilling" to keep it from gettting trashed

6) The rear drive bearing failures

7) The windshield issues

8) The really bad low speed handling

....maybe then I would be happy to see a boosted LT with an extra 30 horsepower. I think the brick is an AWESOME engine, but it could never survive boost without a MAJOR rework from the bottom up.

Am I selling mine since I can't stand all of it's faults? Hell no. It has taken me 6 years to get it to where I actually like it! :D
