Very interesting. It looks like they want prototypes only, but what companies will drop the coin in these tough times?

[ducpainter]

Too many rules IMO

[gm2]

no air valves, rpm limits, very limited fuel work, 17" wheels (what?!), spec ECU, no TC/fancy electronics, no carbon brakes, no fancy materials

so basically the only thing that's "prototype" is the chassis.

...it's wss with gp frames and no electronics.

That was my thought.

[zooom]

watch someone like Hyosung come in an kick some arse with some weird mule to develop for the street....

personally...I think they should have gone to 400cc 4 strokes and use that to develop a new breed of RC29's and GS400's and other lil street bikes of the like...

Did you see the claiming rule for engines?!?

20K euro....?

..."Teams refusing to sell when presented with a valid request will be disqualified."

completely bizarre rule.  or does this happen elsewhere and i'm not aware of it?

[Spidey]

I dunno who else does it (WERA might?), but it's often bandied about as a way of enforcement.  AFM was tossing around the idea last year during its rule changing process.  I've only heard of it applied to a complete bike. 

In this form, it ensures that people don't spend too much $ on an engine (no ones gonna spend $100k on an engine that their competitor can buy for $20k) and also ensure that if one team has new super-duper technology, that the rest of the paddock has access to it. It creates kinda weird incentives.

ama has (had?) a claiming rule.

mladin's forks got claimed at loudon in '99... there was accusations that they were sabotaged before the yosh guys turned 'em over.

duhamel's '99 600 supersport daytona winning bike (yes, the whole bike) was claimed. showa wasn't too happy about it because they had a $200k development shock on the bike at the time. i seem to remember that the claiming cost was msrp + $1500 or something like that.

this is an example of the verbiage in the (old 750cc) ama superbike rules:



7. Superbike Component Claiming Rules - 750cc Four Cylinders, 900cc Three Cylinders and 1000cc Twin Cylinders
(a) The following components of 750cc four-cylinder, 900cc three-cylinder and 1000cc twin-cylinder Superbikes are subject to claiming by competitors or the AMA at the prices listed when used in Superbike competition:

Fuel injection throttle body assemblies and electronic control module:
Twin cylinders - $2,500
Four cylinders - $3,500
Four-cylinder carburetor assembly - $3,500

Fork assemblies - $7,500
Shock absorber assembly - $2,500

(b) Claims will be accepted only from riders who competed in the same final event as the rider whose equipment is being claimed.
(c) Claim form and cash or a certified check must be submitted to the Chief Steward or Tech Inspector within 30 minutes of the posting of results.
(d) Once a claim is made, it may not be withdrawn.
(e) Competitors or teams cannot claim their own equipment.
(f) Should there be more than one claim for the same equipment, a drawing will be held to determine the successful claimant.
(g) Upon notice, the rider whose equipment is being claimed must present the motorcycle for impound at tech inspection.
(h) The owner of the claimed equipment must then accept the fee and deliver the specified components.
(i) An eligible claimant is permitted only one successful claim per season.
(j) Teams or individual competitors who have had a component claimed are not subject to an additional claim for a period of four meets within a season.

Who got em?  Casey?   

[gm2]

Who got em?  Casey?   

claimed by LCR in '99.  put on a bike in '06.



and yeah, i had no idea about this.  i get it, kinda makes sense.  but.. weird.

I guess you have a point, but the devil is in the details. What exactly is a "spec" ECU for a company that doesn't make a 600cc bike? Also since really only the big 4 make 600cc scoots everyone else who enters will be running prototypes by definition... Did I misinterpret the rules?

I'm surprised that the only concession they made for cylinder number was the RPM limit though.

in the big boy class, they did it by weight (more cylinders had a higher minimum weight). limiting the revs is probably a more cost effective solution.

[Speeddog]

From the RRW article:

"6.2 Minimum Total Weight: 135kg for 4-cylinder
130kg for 3-cylinder
125kg for 2-cylinder"

I can't imagine anyone would run a twin for a 10kg advantage, or even a triple for 5kg.
