I bought a 450r about a week ago. One of my friend's was asking me how many actual cc's it has, so i told him to look on the side of the engine where company's usually put the displacement. When he told me what it said i was kinda confused. I went over and looked at the engine and it said 650cc. I know that its supposed to be 450, so why does it say 650cc? Is anyone elses atv like this?

 

Guess you didn't notice that that 650 is right below where you put in the TRANSMISSION OIL. There is no volume where you put in the ENGINE OIL, because this motor has a sight glass for that.

Hope this does this mean you haven't changed your oil yet??? Search the term "OIL", and you will find a number of posts on the topic of 450R oils. Change oil on this engine often!

 

It has 450cc.
