occupant said:The 144 was banned from the pro class by the AMA, it is legal in the other ranks. That was changed this last year to allow up to a 153 2 stroke againts the 250f
Chili said:The 153 rule was a proposal that did not pass AMA congress, here is what replaced that proposal and has been passed for the 2008 rulebook.
Proposal #59: Chapter 4, Section S, Paragraph 2A, Page 45: Complete class listing of approved amateur class structure for AMA Motocross events. All classes are approved for competition and promoters must advertise any classes to be run. All classes must have a minimum wheel base of 53" (except Women’s class). All classes may be divided into A, B and C skill levels at the promoter’s discretion.
CLASS NAME DISPLACEMENT RULES
125cc 122cc - 125cc 2-Stroke
250cc 122cc-250cc
Open 122cc-Open cc
14-24 122cc-Open cc
Plus 25 122cc-Open cc
Vet Plus 30 122cc-Open cc
Vet Plus 35 122cc-Open cc

So you can run the 144 in the 250 class against 250F's but you can also run a 250cc 2 stroke in that same class now so you choose 144 or 250?
