Eek KTM 26 wheel to 20 fork?

Hiya! There seems to be an abundance of spacers to make 20mm wheels fit 26mm forks, but are there any the other way round? I have 26mm sumo wheels to fit my 20mm 640E.

Wow, you've got a similar post on every page...

I answered one of your posts a while back here : http://advrider.com/forums/showthread.php?t=853317 and if you read through the linked post you'll find the part # for the 20mm spacers you require...

Sorry about that just a bit impatient and spammy!

So, to make the 2005+ 26mm Supermoto front wheel fit the 2004 Enduro 20mm forks and axle, I need

http://www.ams4ktm.co.uk/category/7-...14&fiche=31930 part 8 (#58409012000) twice?

Just double checking before I buy!

Well to get a 20mm axle to fit a 26mm wheel this part will work but I'm not so sure about the SM wheel fitting as there are other things to consider...

The SM has a different set of triple clamps so that could mean that the fork tubes are spaced further apart in order to fit the wider wheel... Lukas M would be the inmate to ask as it seems that he has done some SM conversions with the WP forks...

Ok, well I will order these spacers as 12 is easier than me making them at work, if they require anything afterwards spacer wise, I will report back with a drawing.

I would make them all at work but there has been a recent crackdown on "government jobs"

Gunner,

You are correct that the SM triples are wider and the axle is longer, however the wheel with the normal hub and wheel spacers will still interchange, as the extra width gets taken up by a wider fork bottom on the left, and a longer "thick" part of the axle on the right. Then there is a brake disc spacer to simulate a wider disc mounting flange.

So with your 26-->20mm adapter wheel spacers he should be good to go.

Lukas

You only need a disc spacer if you have the wider clamps that are on the SM bikes, not your 640E.

Excellent news, most grateful!

Can't wait to give the local(ish) SM track a try! The rear tyre looks unreal!!!
