ok, i messed up in this video. trail should be calculated by a straight line through the steering head, not the centre line of the fork as you need to allow for the triple clamp offset. however this video explains all about the impressive feeling gained from the sps fork feet. we put it on pole position with these fork feet. These fork feet were fitted to our 2024 Husqvarna fs450, which is the same fitment for the ktm smr450.
