500cc components vs 1000 components?

Are most of the components on the 1000cc quads built tougher than the components on the 500cc quads? I’m wondering if my 2010 500cc Renegade will be much more reliable than a 2010 1000cc renegade, for example.

Are the drive train components from the transmission to the axles stronger on the 1000’s but the suspension components are the same? These thoughts don’t keep me awake at night but I am curious.

Thanks.
