I used to ride a Yamaha 360 enduro so heavy isn't a problem! LOL I loved that bike. It was the same as a 400 except a shorter stroke. Had all kinds of torque.It was either a 74 or 76 not exactly sure anymore but I think 74.

I learned all I need to know about life by killing smart people and eating their brains.
