What makes a bike eligible for WSBK

I believe nowadays the rule is 3000 or so bikes have to be mass-produced. I'm pretty sure the KTM and MV are allowed to compete, they just aren't fast enough. Superstock has very little in relation to superbike (tyres/electronics/suspension all changed etc).

I dont think either company has presented a bike for homologation for the very reason you posted above.They just are not fast enough, or they know they cannot spend the amount of money it takes to compete.

Here is the rule. If the Flamini bros decide its in, its in.

No, that would be DMG DSB

Maybe a silly question, but what makes a bike eligible for WSBK

Why can't, for example the MV Agusta F4 run, or the KTM RC8R, or even the 990 Ducati Desmo RR.



I understand that the Desmo is not really a true production bike, but the Aprilia RS4V that is used in WSBK is not really a true production bike either. Surely, even a standard Desmo would be a competative package to start with, with 197 Hp as standard, compared to current WSBK Ducati bikes at about 215 Hp.

The Agusta F4 is 185 Hp in standard trim, comparred to the standard Ducati 1198R at 170Hp. Why cant the F4 run.

The KTM RC8R, I don't know much about but is quick in Superstock, so should make a good base for WSBK.

We don't really know how homolgation works b/c there is a private rulebook called the homologation papers. The homologation papers have regulations that do not appear in the rulebook, and the only reason we know it exists is due to technical bulletins that reference homologation papers. For instance, fuel injection pressure is limited, but we don't know the limitation.

2.4.8.17 Fuel supply





The engine control unit (ECU) may be modified or changed.

Fuel pump and fuel pressure regulator must remain same as on the homologated model. (Max pressure will be defined in the homologation papers and the fuel line must be modified to allow standardized checks by technical stewards).

Rev limit. That's all I'm going to say. In my opinion, WSBK is rev limited which means it isn't an appropriate place for premium motorcycles b/c the rev limit makes all engines more or less equal. The D16RR which can make 300hp at over 18,000rpm in race trim, and it would be impractical to detune the bike by 100hp for WSBK competition. MV Agusta probably doesn't race b/c they are a premium brand and they have nothing to gain by racing against $12,000 bikes in a rev limited series. However, the Castiglioni's own MV Agusta again so they move go racing anyway.



Rev limited competition isn't good for twins either. The old 999R was running at it's absolute max potential which made it a very expensive bike to campaign. Ducati asked for extra capacity, but they had to accept an air restrictor as well. The air restrictor is probably keeping KTM away, though, they probably lack the funds and technical expertise to go racing. They are also 10cc short of the capacity limit.



Take it for what it's worth. They keep 990cc MotoGP replicas out of WSBK with homologation papers.

Lets do the time warp agaaaain. Its just a jump to the left





The new 11 model is 1195cc, or so they say.

How is the RSV4 not a true production bike?



For MV and KTM it's more because of funding. I definetly think that the RC8R can be competitive if it has a well funded team behind it. KTM does have a factory team in IDM where they are very competitive.
