Hi, I am part of a new FSAE team here at Marquette University and I am in charge for the frame design. I wanted to know if anyone had any Solidworks model for the engine of a Suzuki GSX-R 600. Thanks a lot!

There's one here. You can convert the Step one using Solidworks. It's pretty rough, and there's a couple things that aren't modeled, but the general dimensions are pretty good.
