they stopped making it in 1999. Are you wondering if they're really the same thing? No. Are you wondering if they have pretty much the same engine? No lol. Read the wiki page. I think the ZX-2R had almost 40-45 HP whereas the new 250r has roughly 25hp. It was pretty much a maxed out 250cc engine. It was a 4 freakin cylinder engine with a 4 into 1 exhaust!
