    In my opinion... ;)

    Fender? yeah whatever suits...
    GPS? I swap from nav tower with roadbook and nav tower with GPS and having the GPS at the position of the roadbook is probably as high or higher than Walter had it on his X challenge. That Nav tower is really in your face unless you measure 10 feet tall like Lyndon :lol3
    HID actually works well in those projectors because they are projector lenses and not standard parabolic headlights. Also LED are great but they don't give the depth or range of HID. The reason we don't use them on rally cars for long range beams.
    Trust me tons of braking power, using more than the index finger on the lever is a waste of energy :deal

    But I'm curious also to get Walters impresions

    BTW nice build Bli55:thumb

    Ok, I'm not trying to be a dick about it, and both Lyndon and Walter have my true respect, but coming back on the RFR vs Enduro differences that we discussed earlier.
    Regarding the swing arm length, since Lyndon was pretty busy organising his Baja race and changing continent I managed to get the RFR swing arm length as at the race I attended and finished last week one of the riders was sporting a 2012 450 RFR. He was kind enough (although probably sounded a bit weird and since I asked at the beginning of the race and not at the end :D) to let me measure the swing arm on his awesome looking rally bike.

    Real life differences between the RFR and the 690 Enduro swingarm are around 5mm with the same adjustment hole length, so pretty sure the high speed stability will never come from this insignificant difference.

    Sure! Nothing fancy, just a 2012 KTM 450 Rally Replica (that finished two times the Dakar).

    Hey there Bli55

    1) No plans to raise front fender. Thats an OEM rally fairing as use by Coma and Despres et al for 7-8 years throughout the life of the 690/1st gen 450 rally. I personally have never had an issue with low fenders. I may change it at a later date for an alternative that mrwwwhite is developing, but happy going with OEM for now.
    2) Its not 100% at the top, but its pretty close ... GPS goes in the space right under the Voyager (see empty mount in pic below).
    3) Yes a HID transplant awaits. Its a Hella sealed projector with a 9005 bulb in it. The Hella's are sturdy units, even if their light distribution is not exactly awesome. With a HID in there, it will be a decent low beam, but far from the level I have been used to on the X-Challenge with twin infinity projectors.
    4) Same brembo brake caliper as the XC --- can put whatever disc I want on it. Lyndon has a galfer on there I believe at the moment. I still havent ridden the bike yet but cant see myself questioning his call.

    That thing sounds like perfection.
    Do you spend a lot of time on the jetting or is the stock stuff pretty good?

    There's quite a bit of change in the carb, the jetting is pretty close stock but its all the other small changes to other systems in the carb that make the difference. The full package, LPR modifications and jetting set correctly that makes it so sweet.

    Yes the devils in the detail.
    I hope your customers appreciate that.

    Have you ever done 43.5mm fcr on a rfr?

    No because typically without heavy head modifications it's not appropriate. I ran an over bored LPR carb on my Supermoto bike back in the day but that was with a lot of head work.
