Or go non genuine, Racetech, Teknik plus a myriad of others. Not hard to source. You can even get them made for a reasonable price if all else fails.

The springs i listed are aftermarket WP, its just that KTM handles WP Suspension these days. All WP numbers are in the KTM database. The ones i listed are for Marzocchis from 35mm up to about 42mm or so. Eibach might be another option too.I am sure RT would have a solution though.

Thanks for the help so far - but not out of the woods yet..

Manual states part #514353, with a free length of 630mm,
No rate indicated.

The rear spring is listed at 564.04.011.200,

Unfortunately this doesn.t match yet.
