I don't have time to chime in with an elaborate explanation, but I think for the most part, I agree with 95% of Lex's argument about the 125/250 vs. WSBK/AMA debate.
Let me say first off that both sides obviously 'prefer' one or the other, so please, its no disrespect to those who think these lower classes are superior--Sorry Rog & Liz, and who ever else (I respect your well thought out opinion). (And, just because we may 'prefer' it, doesn't mean we don't follow the lower classes or have a fair idea what they are about (we do get coverage, just not like you guys; live & timely, trust me, we envy you on this). So having said that, I agree that the lower classes are legit but not to the point of saying they are 'any more' legit than WSBK/AMA titles.
Lets remember, this debate got started in reference to Marco Melandri in regards to his credentials as a deserving MotoGP regular. So for the record, he does merit his MotoGP status as a top world class rider. I think in particular, the reference was whether he had the 'stuff' of a ‘premier’ class champion (which ‘premier’ should mean a bit more). Somebody put it like this here in this thread--as a "real" ‘world champion’. Well this "real world" tag seems to have sparked off this debate. Lately, I'm leaning towards he does not have the 'stuff' to be a ‘premier’ class champ, but I don't think this in reference to his work ethic, and certainly NOT because I don't think his lower class championship is worthy or legitimate. I'm playing the physiologist card and I'm going to say, he seems a bit too soft mentally. (NO, I' not a mind reader or learned physiologist, so please put away your rebuttal). But simply speculating (as we all do) from his interviews, his mannerism when frustrated, his honest and open diary entries, and frankly his unprofessional tantrums that he has displayed, to me seem to indicated a rather immature man. In short, I think he lacks the character to perform under tremendous pressure unique in the ‘premier’ class (which is special) for an entire season as has been displayed by recent champions Rossi, Hayden, and Stoner. I think when faced with adversity, he crumbles a bit, and has difficulty bouncing back or working through the problem. Again, for those of his fans (save the flames BG, I count myself as one) its just how he has come across to me in the last year.
So back to the subtopic debate: Since the standard of comparison seems to be made in reference to who is successful in MotoGP, well there is a rather a simple explanation for this for the lower classes to have success in the premier class. The 125/250 riders are reared in the MotoGP 'system'. That means exposure to development, tracks, mentorships, and all things MotoGP, etc. So really, is it any wonder they fully understand what to expect and how to be successful in MotoGP? After all, only the best graduate to the premier class! I've said it before, but I suppose its fitting here to say that I believe if you took any (yes including Rossi, the current standard of greatness) and put them into the AMA/WSBK, I doubt they would win a title outright (as one might think). Obviously this is just a matter of opinion, if you disagree, that's fine, we'll probably never know. But imagine, they would have to get use to bikes that are heavier, power characteristics, more power (at the moment), faster bikes (in a line), track layouts, the superbike system of things, different tires (this is huge), etc., etc. They would have to compete with pretty good riders who know all this already.
In brief, both WSBK/AMA are as legit and deserving of merit as 250s. This is not to say by legit that they are equal. I personally would exclude 125s as they are no more than a rookies cup to me (my opinion, you may disagree—of course you would be wrong though). Now this brings me to the "WORLD" tag of my post. I’ve seen it written here before, and my buddy Rog again alluded to the tag given to some sports. Usually of course it pokes fun at the title “World” given to a ‘national’ sport. Well what makes it a “World” championship? I suppose just this question alone can get its own thread, but here is what I think. The title “world” should be conferred on a sport series that encompasses the “world’s” best at that level, not necessarily ‘around the world. Let me explain, if we have the world’s best athletes in one league, say Major League Baseball, here in the US. Then it would seem ok to call it a “World Series.” After all, the players are the ‘best’ in the world and come from many assorted countries that send their best. The problem I suspect some people have is that US MLB baseball is not played in international venues (except Canada—but who are we kidding, it more like a 51st State). But to me, so what, the ‘world’s’ best happen to all play here in out league. So I’m ok with the tag “World Series” of baseball.
Moreover, I am not so convinced that the 125 and even the 250 series is rightly a “world” championship because clearly, they are NOT the best ‘motorcycle racers’ in the world (otherwise they’d be in MotoGP/WSBK). They are more akin to compare as the baseball’s minor leagues. The minor leagues do have a championship series, but it’s not the “World Series”, and that makes sense. They are not in the major leagues! So I’m not fond of calling 125/250 “World” championships, and I usually don’t refer to them this way. Are they significant? Yes. Are they considered in par to a MotoGP or WSBK championship, I think not.
Anyway, so much for not having time to chime in and elaborate….
