    This K100RT is somewhat along those lines. It wouldn't take much for it to become a cafe bike instead of a rat bike.

    Is that a trailer or a single-sided wheelie bar?

    Isn't that K100 for sale in Las Vegas for $1,500.00?
    I've not seen many K bikes converted to cafe racers. Maybe because you could just buy an RS. From what I hear, the handling is pretty good, and there's certainly enough power on tap.

    FIve or six years ago I saw a really sweet one running around Portland OR - it had a bunch of one-off alloy bodywork from what I could tell. Someone from Portland know the bike?

    The bike you are describing had a small fortune in Evan Wilcox bodywork I'm told. It was sold on fleabay, went to NY, got painted flat black, went on ebay again...

    I got few Airheads and just got my second K100rs. Love them all in a different way. K-bikes are heavier, but handle very well for what they are and have plenty of power. Very linear power delivery from idle to 5000 RPM and after 5K they pull really hard. I prefer Ks for 2 up combat touring.

    My K1100RS is slowly going down this path - its now a single seater, with no fairing, just waiting on a good headlight/bars combo.

    going to use as a commuter for rest of year, then maybe a tourer or go for a special - it cost me next to nothing and is mechanically A1.

    ABS is coming off soon, so space for underseat exhaust in the future.....

    pics soon.

    Yes, I'm building one - or three.

    I'm on the Mk3 version of my Streetfighter and there's a Modern Race Replica and a 1960's Brit Style Cafe Racer under way.

    All have taken waaay too long. The Fighter will be pulled down for paint and detailing this Winter - after I've finalised the fitting of the K1100 front forks and K1200 5 spoke Wobbly wheel [ to match the 5" 5 spoke rear].

    The Race Rep progress stalled mid-year due to too many projects and too little cash - that has 5.5" K1200S rear 5 spoke and K1200 front. This one's easy as all I've had to do - is basically what BMW did when they were developing the S1000RR - fit a Yam R6 fairing [ clip-ons, rearsets, underseat exhaust...........]

    And finally - the 60's Brit style Cafe Racer. This is my era [ there in the day ] so I have pretty firm ideas about what I want to see in the build up - Wire spoked alloy rimmed wheels a must, clip-ons, rearsets, "lose" the radiator, period Goldie silencer, chrome headlamp brackets with chrome headlamp and 2 x instrument pods [ a la Goldie etc.]

    A sense of self preservation means I am keeping the disc brakes, and the tank - although polished alloy - is totally the wrong shape for theperiod. I'm working on an AJS7R or Manx 5 gall tank cover.

    All the delays of this year mean that the Cafe Racer is not much more than a pile of parts - all the right parts + the donor bike.

    All bikes are fitted with the RAM shocker from Realm Engineering in 1" shorter version that I helped to develop. Why 1" shorter? Due to my inside leg measurement and the propensity to do Monty Python fall offs when stationary !

    I find the Kays excellent fodder for "playing" - cheap, plentiful and reasonable power. Oh yes, there's also a Reverse Y trike development [ based on a K100RS ] that took up quite a bit of my "spare " time this year.

    You know, that would be an interesting project, but a little more radical. K bikes are cheap it seems. I think the main thing I would do would be to shit can the huge ugly air box and go with a set of pods. That would look bitchin. Might not work as well as the box but look a ton better. Is the FI on a K bike easy to tweak for a free flowing exhaust and intake?

    Anyone got a picture of a K bike setup that way?

    Nearly impossible. The flapper valve for the fuel injection is at the mouth of the airbox. You would have to completly redo the fuel injection. Sounds like fun, let's do it. Picture three velocity stacks sticking out to the side.
