In terms of tire diameter, both bikes have 17-inch front and rear tires, which offer good traction and stability.

The Yamaha XJ6 2009 has a wheelbase of 1440mm, while the Kawasaki Z900 70kW 2018 has a slightly longer wheelbase of 1450mm. The longer wheelbase of the Kawasaki can contribute to better stability at higher speeds.

In terms of seat height, the Yamaha XJ6 2009 has a seat height of 785mm, while the Kawasaki Z900 70kW 2018 has a slightly higher seat height of 795mm. This means that the Kawasaki may be slightly less accessible for shorter riders.

Kawasaki Z900 70kW 2018

In terms of strengths, the Yamaha XJ6 2009 is praised for its rider-friendly performance characteristics, optimal clutch, playful and lighter handling, seat comfort, individual look, and high-quality construction. It is also described as young and aggressive.

On the other hand, the Kawasaki Z900 70kW 2018 is praised for its smooth engine with punch at approximately 6000 rpm, finely controllable brakes, smooth running engine ideal for city traffic, stable performance at motorway speeds, and good handling. It is also noted for its typical 4-cylinder shriek, although it is described as being restrained at low revs.

In terms of weaknesses, the Yamaha XJ6 2009 is criticized for its design components not being too demanding and its torque development.

On the other hand, the Kawasaki Z900 70kW 2018 is noted to be quite small for tall people, have a rather high weight of 210kg, and have relatively poor acceleration with 48hp due to its weight.

Overall, the Kawasaki Z900 70kW 2018 offers a more powerful and potentially faster riding experience with its higher engine power, torque, and larger displacement. However, the Yamaha XJ6 2009 has its own strengths in terms of rider-friendly performance characteristics, handling, and seat comfort. It ultimately comes down to personal preference and priorities when choosing between these two bikes.
