Yamaha's reversed-cylinder YZ450F debuted for 2010, and it's garnered plenty of attention. Not all of that attention has been good, though, and Yamaha hopes to reverse that trend with an all-new 450 for 2014. But some have decided to go in the other direction. The previous-gen YZ450F, last built for 2009, is still popular. Our man Andy Bowyer had one sitting in the garage and treated it to a super sano, mega trick custom rebuild, producing one of the coolest-looking Yamahas you'll ever see. This bike touches on all the generations of YZ performance. Just have a look.
