Why are bikes older than 5 years old banned from racing supercross?
Sorry for that incredibly long sentence

no where in the rules does it say that a bike that is 5 years old cannot be homologated. Nor does it say that a bike cannot be re-homologated after 5 years.
the only thing it says, absolutely, is that homologation lasts until it no longer complies with the rules or 5 years.
I'm not saying they would homologate an old bike. They disclaim that homologation is up to their discretion anyway, which is sort of blanket statement that pretty much means they don't have to approve shit if they dont want to.
from the AMA pro motocross rules section;
3.1 Motorcycle Homologation
Motorcycles used in motocross competition require homologation approval granted by AMA Pro Racing prior to
use in competition. Homologation rules are intended to give freedom to modify or replace some of the parts in the
interest of safety, research and development, with constraints imposed to limit cost. Superseded or redesigned
parts must be submitted to AMA Pro Racing for review and approval prior to use in competition. These parts must
be listed in the current OEM parts list supplied to AMA Pro Racing.
a. Only motorcycles homologated by AMA Pro Racing may be used in competition. AMA Pro Racing will only
accept applications for homologation from motorcycle manufacturers or their distributors.
b. Once a motorcycle has been homologated, it may be used until such time that the homologated motorcycle
no longer complies with the technical rules or a maximum of five (5) years.
c. Compliance with homologation requirements will not guarantee AMA Pro Racing homologation approval.
Homologation may be withheld or withdrawn for just cause deemed in the best interest of the sport by AMA
Pro Racing.
d. Homologation procedure and information is available from the AMA Pro Racing Technical Department.
no longer complies with the technical rules or a maximum of five (5) years."
The way I read it, they are "banned" after five years and would not be eligible to race after that time no matter what.
Just like 250cc two strokes in the 250cc class, they are not eligible, therefore, by extension they are banned.
Pit Row
A manufacturer would have to make 500 units of said year bike (over 5 years) to be eligible for for re-homologation and that makes no sense when said bike has already been thru the process.
But like always say "the AMA has never been accused of being smart"
That's why I said no manufacturer would take the time and expense to homologate a 5 year old model.
I guess I should've been more specific with my reply by saying no manufacturer would take the time and expense to produce and manufacture enough models of a 5 year old bike to make it eligible to be re-homolagted.
Totally agree with your comment about the AMA.
LOL!
So a 2000 kx250 was raced professionally and poured over by officials upon release.
So it's already been accepted as an ama race bike in the year 2000.
What's changed with that bike? Same frame/motor as oem in 2000 as today right? Run it then.
TripleFive quoted, “It's a joke to assume that the officials are capable of ensuring that current factory bikes are adhering to the production rule”
I would bet $100 I could push a 10 year old KX450 through AMA Technical Inspection and not get caught. If you wrote “2017 KX450” on your signup sheet, had the correct Backgrounds, Numbers, and MX Sports stickers.
• Anyone that’s ever raced an AMA National would chuckle knowing my statement is correct.
I have a good two-stroke homologation story, where Roger Decoster saved the day, for another time.
Who was it that did that video series sneaking into the pro pits?
