[QUOTE="oldguy, post: 1146465, member: 16965"] In talking with Eric Gorr he said that the KTM144 now has a 125 cylinder included with it so they are technically manufactured as a 125 that just happens to have the 144 attached. This makes it legal. the other brands are legal if they were 125s and bored to 144 and not jumped in displacement by stroking or bore with stroking. Not sure how the porting is going to be judged. As usual the AMA is clueless about th rules it has made and has no idea how to enforce/interpret them [/QUOTE]
