This one is fascinating to watch. Try this idea on for size.

A production motorcycle is one that is homologated for WSB, Superstock
1000 or WSS600. The limits are rising to 3000 per year. If it's not
homologated for this, it must be a prototype and therefore eligible for
use in a GP formula. In other words, what used to be called a
homologation special, a short run special version of a road bike, *may*
get round the FIM-FGSport agreement.

Of course the problem is that no manufacturer has ever produced a short
run 600 special. But imagine that Honda produce a run of 100-500
CBR600-RRSP with sand cast cases, barrels and heads. They could
effectively create a one make replacement for 250GP. The bike would be
like a Ten Kate WSS600 bike with any level of tune desired by the rules
and at pretty much any price point from a Ten Kate WSS600 upwards. And
you could imagine them selling engines to somebody like Moriwaki but
being Honda they'd probably be leased and you wouldn't be able to get
one without the right connections. And all the indications are that
Honda want a one make Honda series.

And it's hard to imagine Suzuki or Kawasaki doing the same short run of
a competitive bike and a bit of a stretch to imagine Yamaha doing it.
Ducati know how to do this, with their long history of homologation
specials, but they don't have a 4 and aren't likely to any time soon.

Now Dorna want to try and keep the price down, because one of the big
stumbling blocks at the moment is Aprilia lease costs. So they're
talking about dumb 1999 ECUs and carburettors! Along with steel valve
springs, cam limits, crank/conrod/piston limits. The way they're talking
it sounds like they want something sub-WSS600. Carbs, ferchrissake!
Imagine a 120hp AMA FX [1] formula produced from bikes that never had a
headlight in the first place.

But now look at KTM. They've got experience of supplying a whole series
with bikes and they've got a 990-V4 back in the workshop. It would be a
big step but I think they know how to build a prototype 500-twin in
enough numbers and at a profit to produce a KTM one make series. And
they're just crazy enough to take on Honda politically. KTM are on a
roll at the moment and have big ambition. It's just about feasible that
Aprilia could join them and produce a short run 500-twin based on the
work they've done with their coming V4 or their SV450/550.

One further thought. If Aprilia is snubbed by all this, would Piaggio
throw their hands up and just leave 125? Or are 125GP Aprilias/Gileras
and Derbis just too important as a marketing tool for their road bikes
and scooters? Because KTM could turn 125GP into a one make series as
well.

So as well as FGSport-FIM vs Dorna-IRTA is this shaping up into a Honda
vs KTM-Aprilia battle? With the other Japanese factories and Ducati
standing on the sidelines because they can take it or leave it.

[1]Oh. Wait. You mean like Daytona SBK?

Where does that come from, is someone saying that?

The word out of Donington was that Honda would be contracted to build a
600cc spec race motor for the new class. That wouldn't be a spec bike,
because there chassis wouldn't be manufactured by Honda. Of course that
doesn't stop Honda from making a chassis. But it probably does stop
Yamaha, Suzuki and Kawasaki from making chassis - would they make
something intended to be run with a Honda motor? No.

And also that the route around the production problem would be to make
the class a non-world championship - apparently the rights to production
racing only apply to world championships, which strikes me as semantics,
but an interesting out.

Oh, jeez, NASCAR is now polluting racing at the world level!

And what controls cost there? Anything truly prototype without
restrictions is an economic loser.

Isn't Aprilia considering a reentry into MotoGP? And they surely
understand why Dorna wants to move beyond two strokes, it's not like
this isn't part of a much larger movement.

The problem there is the production thing, of course. And if they can
get around that by just declaring that the class is not a world
championship, that's great. As you know, I don't think the support
classes should be world championships anyway, given that their purpose
is in part rider development for MotoGP. Not a fan of the spec motor
thing, though.

Comment in the middle of a post-Donington Motorcycle News Article.
Presumably somebody somewhere said it within ear shot of the reporter.

And "not-homologated for WSB = Prototype" is similar semantics.

>Oh, jeez, NASCAR is now polluting racing at the world level!

Quite. Next stop, an engine claiming rule.

A one make formula or a two make formula with a gentleman's agreement
could keep the costs under control. There's no real reason why a Honda
spec series should be any cheaper or more expensive than a KTM spec
series. Where the costs really start spiralling is when it's competitive
between factories.

Who knows. Given enough coffee and opera they'll consider anything.

Some of us don't have a problem with MotoGP, 250, 125, SBK, WSS600 all
being "World" championships.

I hate to see this change but if this is what it will take to get the junior
classes to Laguna Seca.

Well if there's no DGM racing at Laguna during MotoGP weekend, there's
no reason the other two classes can't come over just as they will for
Indianapolis
