Technically, the Cafe Racer market still has a lot of room for improvement/building. It's still a niche scene basically. Therefore, I love magazines, great articles, pictures, builds, product testing, etc. Sometimes, you can't use your phone to access the DTT forum while in... certain situations. The internet will forever hold "all the information about everything", but you won't completely ever replace printed media.
Another words, if someone has the time and money to get a DTT magazine going, i'd subscribe. And if you need help, hit me up. I've worked for two magazine companies in the past, and know a lot of the ins and outs of whats involved.
With that said, Cafe Racer Magazine, MM, CMM already exist, and when you combine those three magazines, you basically get everything you want. I would suggest a magazine that incorporates all of the DTT family/support. As in, Cafe Racers, Brats, Trackers, Bobbers, etc. Kinda like that magazine that came out a few years ago for import car tuner guys, it was basically a monthly magazine about garage builds, and DIY turbo kits, etc. etc. Tapping into the niche of people who build their own parts and bikes due to money restrictions, would be the way to start.
