Anyone know the length of the rods on a Pro 785?

Not sure on the rod length, but I think they're the same as the 650/750/780. (65mm stroke)
Pretty sure it's the crank that gives it the longer stroke. (68mm stroke)

Are the cylinders taller then, or is the piston pin closer to the top of the piston? I thought the rod was a different length due to the longer stroke.

there the same as one of the Polaris 800 storm sleds and hotrods has rods you can use but you have to take alittle off the bottom of the rod because it's alittle thicker and hits the case . PM Hayabusa has the part #s

So the rods are 125mm center-to-center like the 800 storm?
So the 785 crank has 3mm more stroke, and the rods are 5mm longer. So either the cylinders are taller or the pistons have a different compression height. Very interesting...
