Search "leading link trike pictures" on google, then you will see leading link front ends are nothing new.
Leading link front ends and three wheeled machines go hand in hand. They are good for reducing trail (making them easier to steer) whilst maintaining usable suspension angles. Leading links are far more rigid than forks, but the trade off is additional weight and reduced wheel travel
If our ATC's never evolved into HIPO MX machines, my guess is there would have been more Leading link three wheelers made
