    Quick list of mods.

    Complete Aprillia SXV brake system + Axial to Radial Adaptor + 320mm rotor.

    TM42 Pumper carb.

    Wheels.

    Anything other than that is luxury. People keep telling me I need to look at the suspension next. Stiffer springs...

    What type of wheels are you using Crobbo? cush hub? I was thinking of getting something with a cush hub seeing its going to spend most of its time on the street. Theres a nice set on gumtree at the moment I'm eyeing off but not sure i want spokes or to go cast.

    A mate of mine built one a while back. I'll see if I can find a pic. He got just under 70 seconds at Barbs if I recall. It has some ugly arse wheels on it though.

    I've got a spoked set here I'm willing to sell. Took them off my old XR and put newer fancier ones on. Have an oversized rotor, and offset bracket, also a 320mm EBC front disc.
    Rear has a small crack but didn't expand/lengthen in the few thousand K's of riding I did on them. Also have a 4.25" rim you could also acquire and swap out.

    Don't stress too much on cush as they have a cush unit in the clutch.

    Spokes are SUBSTANTIALLY better than cast, as cast will crack under duress (i.e. jumps/kerbs/retard riding).

    As Shady said they have cush rubbers in the clutch hub.

    $2300 is a bit exy, but you get a set of brakes as well, the Beringer master is probably worth 4-500 by itself, add in the rotor and you're not too bad off.

    The tyres are shit though I'd wear them out and go for a set of S21s.

    The Excel/Talon setup is probably the best there is.

    Make sure they come with the correct spacers.

    Mine is approaching 30,000ks with filters oil and the odd valve adjustment. Burns some oil but meh.

    if you could get the set for around the $1800-2000 mark you'd be laughing.

    Yeah not sure if they will fit these...

    [IMG][/IMG]

    06 crf450 forks courtesy of gumtree which is why i might have to do a custom setup with the wheels. Have to do a little research on spindle sizes etc...

    If anybody has done the fork conversion I'd be happy to hear about it.

    I couldn't find a full size photo of my mates XR. You can see the ugly-arse wheels and how much he stripped it back. He put a big carb and got the weight way down and was running some tiny rear sprocket on it. He left the rear brake standard and put a slightly bigger one on the front. He didn't brake much.

    How many times have your brakes blown a head gasket or made cappucinos ? Can't be from an SXV if it hasn't done that..
    Rest in Peace

    I have a pair of XR400 factory supermoto wheels, which I may part with. The front is only a 3 inch wide rim & the cush drive unit is missing. Just seeing if they can be made to fit the TTT600 I just bought....

    So started stripping the front today.

    Here is the fork in the road.

    [IMG][/IMG]

    [IMG][/IMG]

    The bottom bearing in the xr is the same as the crf. In the photos above the top bearings and stems are different. So 2 options exist

    1. I can buy a bearing to suit the crf stem diameter and xr frame. It exists after a lot of digging but is 12mm thick instead of 16 meaning i would need a spacer as well. Bearing number is 32906 if you are interested.

    2. Machine down the crf stem to suit the xr top bearing. Possible concern here is that the material used and taking too much away from the stem will weaken it. The xr looks like steel and the crf an alloy.

    [IMG][/IMG]

    I kind of like the 2nd option as it means if I want to swap the forks over then the bearing is the same. Could leave the xr front as dirt setup and the crf as a road setup. Just means the crf stem will be just a dedicated xr conversion.

    Everything else looks about the same dimensions.

    Does anybody know a good machine shop that will do the job at a reasonable cost?

    So Ive been thinking about this more and after digging around on other forums I found a reference for All Balls Racing. They have a handy fork bearing conversion table I was unaware of.

    Link is here -

    http://www.allballsracing.com/index.php/forkconversion

    Just chuck in your bike details and it comes up with fork combinations and the bearings that allow you to do the conversion. Whether the forks will fit is entirely another matter...

    Might be easier down this path using a bearing instead of machining parts as I know these forks will fit. Only problem that I have found through forum discussion is the race the bearing sits in is very narrow and may be extremely hard to get out for changing back to the original race. Which i was hoping to do easily.

    Perhaps to get the race out easily I could space it to be able to get a tool underneath. I am really kinda hoping that the angle of the new bearing will be the same as the original and i can still use the original race just that the new bearing will sit a little higher up in it?

    You might be asking why bother just leave it as is however I just like the look for motard setup. From what I have read it is an upgrade but that is subjective. Plus the bike came with an acerbis long range setup and some stiffer springs so i want to put those in the original forks and have an adventure touring setup thats an easy install.

    Only thing to do now is go ahead and get one and see.

    PS Sorry for lengthy post.
