The stickyness of WP's can be significantly reduced by using SKF's new stiction free fork seals. They aren't cheap, but do make a huge difference on the initial movement of the fork.

Do you pre-grease/oil the SKF seals? I have done 2 sets of forks with the SKF "stiction free" seals and both suffer from terrible stiction now.

thanks for the advices guys!!!
I think I will go for a 48mm, because it's the cheapest I can find right now.

My Dakar has a YZ front end and yokes which doesn't incorporate a steering lock. I now also have a GPR V4 steering damper from a WR450 that I wanted to fit.
A bit of 3D design work and a contact with some 6082T6 and a CNC milling machine.
Cost of materials and machining was £120. The design cost was just my time.
Hi,
Great work, these look very very good indeed.
Could you make a 3D design of the stock triple clamps?
I have stripped threads on mine and been looking for some time for someone who could fabricate CNC machined ones.
It would be much easier if I had the 3D design.
Love my Marzoccho Shivers with custom Hyperpro rebuild by Bas at Hyperpro. Completely changes my bike
I remembered the smile on your face when you came back in after that first test ride Peter
How's the fridge for Lefe?
You purchased the forks and had all that work done by the names mentioned for less than a grand.....really? So I guess you are still running a standard front wheel of cheese?
The difference I can not tell between, I have bikes here with both forks on, and set-up very similar to my style of plodding..... both perform as well as each other.
Owners tend to fit whatever can be sourced for their budget, the 690eR forks are fairly easy to obtain and give excellent results per buck.
Whilst I'm on.....anyone had any joy sourcing a rear wheel without a cush-drive?
Still not found an Aprilia SXV hub? Have you spoken to Talon at all?
I'm still waiting for cush drive rubbers to turn up
Yes and yes. I bought a second hand pair of X Challenge forks off one of the guys on here. Posted them to Eric at HotRod welding. Eric stripped the forks down, had the bottom lathed so as to allow adjustment top and bottom for the Shivers. A few weeks later I rode the bike over to Holland and met Bas. He already had my forks and set about setting up and fitting front forks. Whilst there Bas (having much experience of these little bikes) made many small tweaks and improvements. Also had larger foot rests fitted and a rear shock built to match. Yes my bill was circa €1000! And given the great exchange rate at the time was very reasonable.
I use the standard X Country wheels for road and easy lane use. I later purchased a set of new take off X Challenge rims, which have worked fine up to now. I've a good few thousand miles done off road, good speed on trails and single track in Spain. And more gnarly terrain in Ireland North and South. For now the wheels will do, when my "cheese" rims fail I'll replace the rims and spokes with more focuses rims. Until then my little 650 continues to surprise me. So 6000 miles later I'm very happy. Much more happy than with my old X Challenge. Even managed joint 2nd on it at the Paddy Dakar this year. Maybe my fat ass places more weight on the back of the bike saving the front wheel or my optician is better than others. But in answer to your "really" question the answer is YES SIR. It can be done for under £1k sterling.
Hi Micky
My good lady always keeps a couple of Leffe in the fridge, she's good to me! Yes I remember the difference well. In fact landing off a 70mph off road jump this past Autumn brought than stupid grin back, nearly fell off laughing how smooth it landed without fuss, even with Magadan luggage on board. Bas' work was worth every penny. The harder I push the bike and my luck the more I'm surprised by it.

Peter, yes it can, as mine came in at approx £500, having done all the enginering myself. The forks were £200, the 950SE bracket was £50-ish and the new front wheel was £250-ish.
I also fitted an Ohlins rear shock during the build, and all-in-all the bike turned out to be one of the best bikes I have used on sand tracks.
If I was to do the conversion again, I have a few things I would do different.....but that is for another thread, not this one.
The only thing I would like to do next to the bike is improve fuelling, as it seems to be very lean just off tick-over and gives a little hesitation if using it on tighter single track trails.
Oh, and the rear cush-drive as I mentioned must go!
Sounds like a trip to Hilltop in Leicester. I had my bike set up there, one of the best mods to the bike. I also had thought of Ohlins rear but were expensive for me. The custom fit and service I got at Hyperpro was very impressive. Some time in the future I intend to modify an 800gs Hilltop, Hyperpro and HotRod Welding will be first mods on my list. It's good everyone has different approaches and views otherwise the world would be a duller place.
Had my Xcountry to Hilltop a couple of years ago, marvellous, really sorts the fuelling. Yes, they're very weak as standard .... Geoff really made the 'bike an absolute delight to ride. Pulls like a steam train from low revs, and doesn't use any more fuel

Presumably you need a power commander or some sort though, as I don't recall anyone mentioning that our ECUs were open to play with. I should have got mine done really.
It is the low to mid range of the throttle that feels weak. as I said, just the area of throttle you would use if riding a technical section or single track. The full throttle appears to be fine, and fuel consumption is excellent.
I'll give the bloke at Hilltop a call. What sort of prices are we looking at for his services?
You should be able to get it done at Chester Motorrad, I had the XC, that Ange briefly, done there for free, certainly improved the vagueness at low revs.
No Power Commander required ... just a remap by Geoff at Hilltop. Worth every penny
After the Hilltop Remap the Xcountry just pulls like a steam train all the way through. OK, sounds daft, but believe me it becomes soooo smooooth. None of the chunkiness of a big single pop pop popping along the roads'n tracks. Will bimble along in a thirty limit in fourth gear and yet have instant acceleration, no struggling for breath. As for price you'll have to ring Geoff ... we got a deal for four of us in the day
I guess that was just the BMW Software update though Tim ... not a complete remap, rolling road, sniffer up the exhaust etc.
