OT: raptor 660

Hey did you guys see the YFZ450? Cool hey?

Concerning the raptor, in the spec sheet they say it is liquid cooled but when I look at the picture, the cylinder rather looks like an air cooled....what's going on? Old picture?

In addition to water cooling they have fins on the head and cylinder to aid in cooling. They are really popular in the sand dunes where engine speeds are high and air flow through the radiator is low. This is where every bit of cooling helps.

Wow :D, I had never heard about it...

For sure here in Quebec cooling is never a problem... :D

Thank you for the information :)
