The Ogre is the Karate Monkey as was with a few more braze on’s. The Monkey is now disc only having lost the Canti Boss’s which the Ogre still has. Thw KM, still has the threaded Barrel’s on the rear stays for a rack, but if you are wanting racks and guards, then I’d say the Ogre.
Just built myself a Karate Monkey for winter and i’m loving it
Welcome to pop round and have a look Tony if you are near Micky woods, its a 20″ so probably too small for you, but it will give you an idea.
