[WhiteBros400ex]

Can you race quads that are not production still i heard they where switching to all production quads i am going to do mx and i was going to buy this yzf426 off here because it al ready has suspension and eveyything i will need or a new stock 450r. If i can still race a 426 i will most luckly get that.
