Slanting Bultaco Pursang Shocks

From the days of long travel suspension development for dirtbikes comes this 1975 Popular Cycling article. Your Pursang might handle OK but this is all you have to do to increase the rear suspension travel to an unheard-of 7.5 inches! I won't include the actual instructions as you won't be doing this to your now-collectable bike but if you found a Pursang frame that appears to have been modified, it isn't a factory prototype, it's probably a home-mangled bodge job.

Start with this...

 Apply hacksaw and large noisy grinder...

A little (yawn) torch work... end up with this. Easy Peasy.
