Both bikes share a similar footprint on the scale, with only a negligible 1kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Bottom Line: While both are capable, the 675nk offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
