If technical is what you're after, then the excellent Back Street Heroes magazine ( http://www.backstreetheroes.com/ ) has a regular helping of technical articles that I write, and I can also recommend TheFont ( http://www.thefont.info/ ) if your web browsing experience would be enriched by some technical discourse.
I was hoping that this would be a little more "Zen and the Art" and a little less "Motorcycle Maintenance", so to speak.
Take this BMW for instance, the R65. It's not happy is it? It's been hanging around in a garden for 10 years judging by the date the tax expired.
It's interesting that according to the DVLA, there are numerous millions of untaxed vehicles running around the roads of this sceptred isle. Or possibly, they're parked in back gardens, sheds and garages, much as this BMW has been and the 20 or so other derelict, semi-derelict, and just plain forgotten why it's not up together, motorcycles I have lying around the place, have been. It's a fair bet that I know at least three other people, none of whom know each other, who each have similar quantities of similar vehicles. I wouldn't be at all surprised if each of those three people knew two other people with their own accretion of rolling stock.
So the DVLA loses money, processing the millions of SORN forms where we all tell the government that we're not committing an offence, and that we haven't ridden any of the numerous non functional motorcycles we posses. Which raises not a penny of the mythical "lost revenue" that the DVLA has harped on about for years.
I would imagine that the DVLA could quite probably stop losing quite so much of the taxpayer's money, were they to put their hand in the air, admit that they'd been quite a bunch of asshats, and abolish the entire SORN thing.
