Surprisingly, it seems bikes look much better in natural conditions than photoshoot environment. Craig Howell has an excellent collection of bike pics in his Flickr album, and one especially for Motorcycles, from Roland Sands to Arlen Ness to vintage Ariel and Vincent and Indian and Knuckeheads to 80s Ducati to 'Legend of The Motorcycle' photos, he has everything. If you are not into plastic finishing and love the old stuff, then the collection is definitely worth a visit from you. Above are some samples from his Flickr album. And oh Yes! Lots of Cafe Racers!
From his website, The Creeper, got to know that he also owns a 1927 BSA besides a few others. And you should take a look at his past collection and his friend's collection (also posted in the website), it will make you drool and go green with envy.
