    Slipper clutch (Duke to RC390) Like New!

    This is an KTM O.E.M. slipper clutch that works on the RC390 (original equipment on the 390 Duke) I bought all the necessary parts to convert a RC390 to a slipper clutch out of the Duke 390. Very little use, (maybe,300 miles) So, it's like new and I guaranty its condition. I paid $350 USD new...

    Fitting RC8 R forks to the 390….. Works Great !!

    Yes, the second picture is of the the spacer/adaptor that fits the left fork leg (as sitting on the bike) also known as "drivers-side" (joke) And yes, stock size wheel spacers are also retained. Also, don't forget and this is very important,… this spacer/adaptor sits in the fork-leg and the...

    Fitting RC8 R forks to the 390….. Works Great !!

    Sorry for the major delay, but as promised, my notes on the RC8/RC390 fork conversion. I'm no machinist or engineer so excuse my amateur attempt at drawing the measurements…. This is what I have….. Keep in mind, I'm also using a single (320mm) front rotor from a Yamaha FZR1000 mounted backwards !

    The "race" side fairing panels out of the Hard parts book are black. I bought a set thinking they were lighter but they aren't, still have the hole for the blinkers too…. They come all black, I added the Moto America stickers...

    All White RC390

    Don't forget, the (white) bike pictured is the "Cup" version. So this early photo, minus-graphics (and being all white) makes sense. I do like it ! (Note the white fork tubes and bottom bracket)

    ### OTD Prices ###

    Apparently, there isn't a very big profit margin on these bikes especially the Cup bike which actually costs the dealer more than the MSRP of $9,999. And my dealer buddy also said that dealer cost on the street version is $5500. So the only profit in it for the dealers is the freight & set-up.

    Wider Tires & Wheels?

    To answer Oldvet, the sizing charts I have seen from one or two tire manufacture specifies a 4:00 inch rim requires a 140 section tire. You need a 4.5 inch wide wheel for a 150 to fit correctly. The reason the stock 150 leaves chicken strips is proof its too big for the rim width. The problem I...
