    I'm not sure what the final cost will be, the one I bought was the last in some old stock that they had, I'd hate to quote a price and be wrong.

    When I talked to them they said they had parts being machined so hopefully they'll have everything soon. Rick and the rest of the people over there were really great to deal with. A+

    From Richard at HOH "
    On the RAD/Hawk adapter parts: "Do you think you can get 5 commitments right away??? we are very close but I need to order a large quantity to get these at lower price" Kits will be anywhere from 550 to 700 plus forks.

    On the forks: "My fork mods are 425.00 incl rebuild and revalve and prog fork springs."

    Seems the $550 is group buy worthy so those on the fence or midway may want to start a buy group.

    What does $550 buy you?
    Axle, washer and nut
    Calliper relocation bracket

    Yeah, even for small runs it seems a little spendy.

    Email I received from Richard

    "Still waiting on final for kit -- have 3 people working on it -- the revalve mod , prog spring rebuild , lower etc on my end runs 425.00 complete"

    Seems the numbers will need some clarification

    I think the $500ish mark is comparable to what Hawk had going w/Rads mod. Maybe price will drop if the Dakar/Sertao crowd get more interested.

    The $425ish for the fork rebuild is same quote I got.

    That and the adapter parts and your stil under a grand using your own GS front end. Adding up the YAM front swap to include wheel, brakes, etc can run close depending on the deals you get.

    i know a lot of you guys are running an 18" rear rim.

    do any of you run this tire AND size :
    Heidenau K60 150/70 18

    if so , any issues with clearance or chain adjustment ?

    thanks

    I think the caliper relocation bracket they are fabbing is pretty elaborate (lot's metal and machining). Does anyone have a picture of this part they can post.

    Did anyone else need to get bar risers for the hand guards to clear the cockpit and give enough room for steering side to side?

    I ordered the Pastrana FMX high bars and hoped it would give enough rise and sweep but I think it put the HDB guards really tight to the cockpit. I had to adjust the steering stops way too much and have no turning radius.

    Looking to get some risers and get some more clearance. Since I have the HDB top clamp I might use the old top clamps from the Aplied Racing triple as a poor mans riser and see how that works.

    My bars are a relatively straight bar, very little rake and they are mounted with risers but in total height are 1/2" lower than stock. I sculpted a little out of the screen each side to get clearances, The side benefit is i no longer have any helmet buffetting which was a problem stock

    It is the excessive rake in the stock bars which give the clearances on the screen but cramp the rider up when up on the pegs

    Hmmm.... I have a couple of other sets of bars I can try out with the Yamaha stock bend and CR High bend. I'll have to test fit and see what will work.

    Just found this on ebay, but can't find any information on the rim spec anywhere.

    Its a trials rim, so not sure if it would be strong enough for use on the dakar, but excel rim and tubless sounds great for the back - what am I missing?

    [​IMG]

    Its 18 x 400 , so not sure how that would compare with 18 x 2.5 inch that I need - Anybody know?

    You going to need a special hub for that rim. The spokes are the opposite way round.
    Good idea though. Super strong rim and tubeless.

    Yep, what other have said above. If you are looking for a rear rim you need a 'euro' spoke pattern, almost every other bike in the world runs a 'jap' pattern. The only other bike that I know of that runs a euro pattern 18 x 2.5 inch rim is the KTM 950SE but that still might not fit (apparently their hub is wider). I ordered mine from Woodies Wheel works, they custom drilled the rim in the correct pattern.

    Cheers,
    Michael

    Good spot, I knew I had missed the obvious! :rofl


    I was thinking about lacing it to the BMW hub

    Thanks good info. Presumably it is possible to lace a BMW euro hub to a Excel jap rim but I am not sure what is needed or how this is done.

    My current rim is 3.0 but the widest excel rim appears to be 2.5

    It's not possible, the holes in the hub point the wrong way.

    Did a search and couldn't find the answer so here goes.

    I have the TT Magura X-Line (28mm) with 60mm risers set up. If I do the YZ swap can I continue to use these risers and handlebar or would I need a new setup?

    I would think so, but you may need to get the holes in the risers lengthened. I had to do that with the Barkbusters risers for the original bars. Now running Fatbars and it all fits.
