Just in the shop today putting my Fox EVOL's on my new Summit X 165 and got to thinking back when CAT came out with the King Cat 154". A LOT of people that grew up riding "long track" 136's, me included thought "what a useless track length for anything but point and shoot high working. you will never be able to turn that thing!!". Today, 154" is considered by many, including me as a "short track" in the mountains lost suitable for smaller (re LIGHTER) riders and there are MANY guys riding 175's that can maneuver better than most of us could back on our 136" old school machines. My how times have changed. Of course the changes in machines goes FAR beyond just the track length but still...
