Looks like they're adopting the 1200cc limit for 4-stroke twins: http://www.superbikeplanet.com/2007/Jul/e/n070711r ule.htm | ||

Interesting.  | ||

I don't see any intake restrictors for the litrebikes. Kinda puts twins down on power a bit. 1000 inline 4 v. 1200 twins is still an advantage to the 4 - unless sales REALLY take off and they put out a Homologation Special built to meet requirements. Even so, the advantage in brute HP will go to the litre-sized I4 bikes. | ||

Ducati seems to think that 1200 cc will be enough of a equalizer to level the playing field. It sure beats playing with straight-up displacement only. This may be the boost needed for the return of a 1200 RC-51 type superbike, and who knows what else. | ||

Sorry if this is a stupid question but what does Homologation mean??? I do not have a dictionary handy. | ||

Basically the process by which which a street legal motorcycle becomes a race bike for a particular AMA class The intent is to make manufacturers build enough street legal motorcycles of the bike they want to race with. IE if brand X sells a 1125cc VTwin bike to the public, a race team can't show up to the track with a 1199cc version of the street bike when the the rules make you race at the displacement that your street legal bike displaces. This keeps manufacturers from only building small number of "special" bikes that are substantially different than the original model and/or not certified street legal in the US. Past examples include the Yamaha R7, HD VR1000. The RR was a special case because the Formula Extreme rules, while mandating that the bikes be based on street legal models, gave air cooled twins unlimited modifications, and the AMA declared it legal. However it penalizes a startup company that has only made a few bikes to begin with, they have to be a certain size before they can build enough bikes to satisfy the requirements, which can take years. Examples would be the MotoCzyz or Fischer. The Tularis was a two stroke so it would never have been street legal. Unfortunately the AMA does not have a class where anything goes, CCS and other santioning bodies do have such classes. here's how the AMA defines it: Homologation - AMA approval process initiated by manufacturers or distributors of motorcycles. Only approved motorcycles may be utilized in most types of AMA competition Manufacturer - The original manufacturer of a motorcycle, not the distributor from page 6 of the rulebook: 1.2 Homologation of Motorcycles a. Only motorcycles homologated by AMA Pro Racing may be used in AMA Road Racing competition. b. Homologation procedure information and applications are available from the AMA Pro Racing office. c. AMA Pro Racing will only review applications for homologation from motorcycle manufacturers or their distributors. d. Once a motorcycle has been approved, it may be used until such time that the homologated motorcycle no longer complies with the technical rules or a maximum of 5 years. e. Compliance with homologation requirements will not guarantee AMA Pro Racing approval. Homologation may be withheld or withdrawn for any reason AMA Pro Racing deems in the best interest of competition. f. A list of eligible motorcycle models for each racing class is available from the AMA Pro Racing office. g. Additional homologation requirements for each class are listed in the associated class standards section. For example the 2007 Homologation rules for Superbike: 2.1 Homologation a. Only homologated motorcycles may be used in Superbike competition. b. Superbike motorcycles must be street certified in the US and available through US retail dealers. Minimum import requirement per model is as follows: 1. Manufacturers with 99 or fewer US retail dealers - 150 units 2. Manufacturers with 100 - 199 US retail dealers - 300 units 3. Manufacturers with more than 200 US retail dealers - 400 units c. See Homologation of Motorcycles under General Equipment Standards.

I htink that the AMA and BSB will adopt slightly different tuning rules for 2008/2009 than the WSB series. As far as I know, the engine tuning will be heavily restricted to the same level as we now have in Superstock, but they will be allowed more latitude on chassis development. This will bring the 1200cc twins further into line with the IL4's and keep costs down for the teams involved. It should also increase the number of privateer and non works teams taking part, but I remain to be convinced on that one. Unfortunately it will probably be the end of Wild Card rides at WSB rounds for local riders though, as they will run completely different rules. | ||

Yes, it's a shame that the organizations can't see their way to synchronizing rules. No problem for the big factories, but it makes it very difficult for the small budget teams and the riders trying to break through onto the big scene. | ||

Thanks for the info and explantion of Rules! |
