Now that the garage full of Yamaha thumpers is relatively stable, I'm feeling the itch for an old two stroke street bike. There are a few different RD350, R5, DS7 options kicking around my locale at the moment in various states of degradation. But for reasons that are probably best left unexplored, I have a real hankering for a Bultaco Metralla. There's a mk8 200 for sale on the local craigslist, running, ratty, mostly together. Dude is asking $3300 for it. That seems steep, but then again this is one of the first gen Metrallas, and therefore might somehow be more valuable in some eyes. There are also scads of Bultaco dirt bikes from the 70s around, and the trend seems to be that Pursangs fetch a lot of coin, Alpinas don't, and Matadors tend to vary greatly depending on condition and state of delusion on the seller's part. But info about Metrallas, and what they may or may not be worth, seems scarce. For my part, I am not concerned about collectibility. I want a small-bore two stroke street bike, totally happy doing a frame up rebuild if need be, but intend to have a bike to ride as opposed to show. But I haven't really been paying attention to the old bike market aside from occasionally gasping in pain when I see shitty old motocross bikes being flogged for $4k on craigslist, and Metrallas aren't too common around here, so I don't know what the general range of worth might be. What words of wisdom do the sage heads here have on the subject? What should a mid-California grease monkey expect to fork over for his next mid-life crisis aversion project?
