I edited and published two small-subscription magazines over the last 20 years. They were not motorcycle related, but had a similar enthusiastic audience. They were doomed secondary to the internet. Small production means relatively high cost. Dues collection was a monumental headache. You can't imagine the number of people who will write you angrily mid-year saying "I paid my dues, where is my magazine." After going through records (time consuming), and establishing that they had not paid, you ask them for a copy of their canceled check (time consuming), they sheepishly reply that they must have forgot to pay, please send all back issues. So now you gather up all the mags he missed, and do an individual mailing (time). This sort of hassle, and the waning interest in paying for magazines when the info is all on-line, make small-time magazines untenable.
If you have a hankering to publish, you can actually solicit articles and advertisers and put it on line in a pdf format. This is what I did with our mag. It was now free to the subscriber, and there was no mailing hassle. When we did a poll to determine how many of the 400 subscribers even printed the mag for free, it was less than six! The reality is that very few people are interested in expending any effort for a printed mag.
