How does the new Z800 stack up against the Z750R on paper?
The Z800 boasts 58cc extra and a slightly higher comparession ratio up from 11.3:1 to 11.9:1, giving it 6bhp more at the top end and an extra 5ftlb of torque, slightly lower in the rev-range compared to the Z750.
The final drive is different too, with the Z800 carrying a 45-tooth rear sprocket, up 2 teeth from the Z750R which will aid acceleration and throttle response.
Despite the Z800's engine being 1kg lighter, the Z750R is 5kg lighter all-in and that's including the Z750R's additional 1.5litres of fuel capacity over the Z800.
There really isn't much in it on paper but subtle changes in ergonomics and chassis setup help the Z800 feel livelier than the Z750R.
