I don't know a lot about motorcycles, but I can appreciate them from an aesthetic perspective: they look nice, and that - in the end - is what this forum is about. This thread is interesting because it's run by a small number of posters who own... a lot of motorcycles. There's also an occasional actual, motorcycle related clothing tip, because what's the point of owning a motorcycle if your protective gear makes you look like a weird dirtbike rally reject?
And, of course, like any website populated by 20-39 year old, upper-middle class men we have a thread cars. And shockingly, the cars that people want to talk about are not Mazda Miatas. Venture down the mid-level BMW/Mercedes/Porsche road (get it - a car pun!) and see what people are renting. Just ignore GreenFrog. He never shuts up.
We have clothing recent purchase threads, so why not a tread for all other types of purchases? Headphones, bikes, bedframes, mattresses, boats, cars, cameras, the possibilities are endless! Some dude even bought a goddamn prop plane, straight out of Vice City and prepped for a marijuana run to the glades.
