Hey guys. Long time. Just wanted to show you guys what the final model is looking like in Houdini. This was all done to build a little animation with a character (you can see more about that here: http://learning3dfromscratch.blogspot.com/2011/08/more-sierra-poses.html and here http://learning3dfromscratch.blogspot.com/2011/07/sierra-strikes-pose.html) riding the bike.

When I exported the bike from Moi the poly count was pretty high, over 1.5 million polys, which I figured was a bit extreme for using in an animation. So I rebuilt the model in modo using subd techniques and then freezing the mesh and further optimizing it where possible. So the below shot is what that final model looks like brought back into Houdini and rendered there (with Motion blur and a first cut at the light trail). The final model has around 400K polys, probably still overkill, but at least more manageable.
