The new RM Kustom® Choppers. Mean, loud and low. Just as they should be. They're all 1:12 scale, so they're big, too. Over 8 inches long when completed. Each has either a long or short style frame and fork. Plus extra parts so you can customize yours with the available two sets of wheels, two fuel tanks, two drive chain covers, two air cleaner covers and two different sets of exhaust pipes.
