If you filed it craftily enough you might still derive some steering stoppage out of the whole foul jamboree!



Thanks for the dimensions, lads.

Yup, I am going to do some more checking and figuring before heading to the machinist.... hope to preserve some steering stop material as you suggest Lornce!

Nice looking, not so cheap
Those sure look like Marzocchi Magnums in 45mm to my eye, but point taken... they do make 'em for 50mm as well.

The Marzocchi's do have the advantage of having comp and rebound adjustable on the fly, where the WP's take a screwdriver... but there are other downsides with 'em as noted on the first post.

Sage advice Ontic. I am borrowing an angle grinder tomorrow and will be doing just what you propose (including the bit about the vice).

The trip's didn't swing far enough to have the tab drop into the open space

Will have to measure later...

Perhaps with the stock KTM stem, but mine is shortened to work with BMW's

Bummer, I have a line on a pair from a guy in Brussels, and I will pass it on to you if I don't buy his internals to be a spare for the one I f'ed-up!

With any luck, I may be able to have the triples on the frame by this weekend and begin fabbing some supports for the headlight unit....

Some fork tuning info from Jay.T who has Extreme's on his R100GS:

Then provided him with weights of me, totally loaded, bike wieght etc, he came up with the rest for the internals. The bike now handle like a dream. I have a list of part numbers he added if you would like. They would have to be KTM part numbers? Let me know.

Brake pads ordered check

Lower triple notched to clear frame tab... check



Yeah, I know that looks a bit rough, but I'n not done yet!!!


BMW Steering head bearings on hand.... check

but it is not as happy an ending as we had hoped

Bearing ID for the KTM stem


And for the BMW


Looks like I need a set of KTM steering head bearings before the trip's are on as they have a 29mm ID to the BMW's 28mm ID... may have to push this out a week or two...

(EDIT- crossed posts with you, photos and more info now)

Oh, you are cruel!

The tuning info regarding oil weight is interesting. I have read other brief write-ups that mention playing around with higher than 5W oil, to good effect...?

So, will the KTM tripples work?

Well. on the first page there is a picture of crazyivan riding his G/S with my lower triple (which was formerly his lower triple) down the road... so I think the chances are very, very good.

Cheers Solo,

OK so, KTM bearings- do you use the KTM races as well, or do you match the KTM bearings with the BMW races? I guess the question is, do you know how the OD of the bearing races compare?

On the other hand,
Is the KTM stem steel as well? It looks a little different (alloy-ish) compared to the beemer one. It looks like there would be plenty of material there to safely turn it down 1mm. The turn-down would be easy enough (for me to get done free) but the re-threading a little more annoying. I am not sure if I know anyone who can cut threads for me for free.... I'll have to find out.

I would imagine that in reducing it only 1mm over-all would not completely remove the previous thread (the valleys would probably still be there?) so if the thread pitch is the same between the beemer and KTM stems/nuts the thread could just be deepened (possibly even very very carefully by hand).
Anyway, if a simple bearing swap does the job then that sounds best. If you have to mix bearings and races every time you change them it might be a little less than ideal for parts availability (say for example having to find/order two different items from a remote place) and for the 'tight-of-arsed'

Anyway, I'm just passing-time and chewing on thoughts. My tank has shipped and my Ohlins has shipped. Still no word from my front-end seller, but still no more activity on his account- I haven't given up hope completely (maybe he is on a really long holiday), but I am a stubborn bastard. Got some pannier frames yesterday that are meant to fit a G/S, but they don't, so they will have to go back to my parts guy.

I've been loosing a lot of auctions on ebay.de lately which is annoying. What the market pays for second hand prices (on parts that are still available new) is bizarre at times, and for parts that I need/desire that are NLA the prices can be really really annoying.

Oh well,
looking forward to the next update,

Wow ... Solo ... I know you probably haven't done any calculations per say ... but cutting into the triple ... eeek.

I'm guessing that you probably won't go to the 'extreme' that the WP / KTM guys were calculating on ... and there appears to be a lot more meat on the triple ...

I just don't know. May the force be with you. Live long and prosper. All that.



PS - Looks good though. And I'll admit ... cutting things like that is something I would probably do ..

That won't break in a hundred years, but you could have been a little gentler/neater about it, you butcher.
