Here's a collection of video I pulled off Youtube. All contain some great footage of Yamaha SR400's & SR500's in action. The Yamaha SR400/SR500 in my opinion is one of the most customisable motorcycles on the market (if you're wanting a retro look). The Japanese do amazing things with these big singles with a plethora of workshops producing amazing SR400/SR500 based Cafe Racers, Bobbers, hardtails, street trackers and much more.
You can read more about the Yamaha SR400 back in this post I did some time ago. I'm hanging out for the day when they start selling these in Australia. If you want one now you need to look to a specialist importer like Deus ex Machina.
