Ah, MZ... "My" first motorcycle. Well, it was my dad's. ETZ151. The dream bike then was ETZ251. Not this blue ETZ250!

Don't know how old are these "concepts", but Gas Gas no longer manufacture this engine (which, by the way, is based on the Suzuki DRZ engine). They have switched to Yamaha WR engines these days.

About a decade ago, MZ were making some really nice bikes, like Baghira and 1000s (and their variations). I'm still waiting to see if they'll come up with something clever again. So far, they've gone till scooters only...
