Lastnline75 is correct, there is no Pro-Trax front available for an oem chassis.
Laeger's only built the Pro-Trax front end to bolt to their 250R geometry banshee chassis.
Laeger's did offer the Pro-Trax front end for most of the popular 450 four stroke bikes, a select few 400's, the original oem 250R and of course their own 250R Pro-Trax chassis bikes.
