being a support the local vendor guy, I went to my local experts, a shop in the next town over from where I live, and the owner lives in my town about 3 miles away from me
this particular vendor
is world renown for it's expertise in dirtbikes , but not so much for streetbikes, but they can get street suspension stuff, if the customer is willing to pay the price, They got in tough with their factory experts in Austria with my requirements
YES, I paid the BIG $$$$ nearly $1500 in total , but for a WP Suspension, (same shock that is in the big KTM Adventure), tuned, and new WP front spring as well 5way adjustable
