..in firts place excuse me if this question has been exposed already :(
in this moment, i´m reading the rulesbook of AMA ATV MX and in the point 1.4 f it sais:
Bore & Stroke must remain as the production model.
it is true?
it´s new for this year?
i thought that riders could modificate and incrase the bore and stroke of their quads :confused:
Doug Gust won tha championship (i think..:rolleyes: ) with a 450cc Z400, Natalie with a 470cc Sparks 450r etc..
wich is the reason of this new rule?
i like to see "stock" quads at the races, but i really like too to see fast quads out there :ermm:
thank you guys and excuse me for possible mistakes with the English i had could make..
