450f
angry,
Ryan was first brought on as a test rider for the 450,Tortelli also tested the 450 and was given first right to do the nationals on it(they have only two or three race bikes right now from what I heard),but he liked (felt more comfortable) his two stroke better.
Ryno REALLY likes the four stroke and he is blistering fast on it.
I saw him at the four stroke national and I know he is going to do very very well on the nationals this year!!Anyways, he is at this point the only one racing it
