Triumph Trident 660 2021 vs. Kawasaki Z900 RS 2018

The Triumph Trident 660 2021 and the Kawasaki Z900 RS 2018 are both naked bikes with similar engine types, fuel systems, and suspension setups. However, there are several key differences between the two models.

In terms of engine power, the Kawasaki Z900 RS 2018 has a clear advantage with 111 HP compared to the Triumph Trident 660 2021's 81 HP. The Z900 RS also offers higher torque at 98.6 Nm compared to the Trident's 64 Nm. This means that the Kawasaki will likely offer more aggressive acceleration and a higher top speed.

Both bikes have liquid-cooled engines and similar displacement, with the Trident at 660 ccm and the Z900 RS at 948 ccm. However, the Trident has three cylinders while the Z900 RS has four, which may result in differences in engine smoothness and power delivery.

In terms of suspension, both bikes feature upside-down telescopic forks at the front and swing arms at the rear. The Trident has a monoshock rear shock absorber with preload adjustment, while the Z900 RS offers additional rebound adjustment. The Z900 RS also has an aluminum rear shock absorber, which may provide a slightly lighter and more responsive feel compared to the Trident's steel shock absorber.

Both bikes have steel frames, but the Trident's frame type is listed as "perimeter" while the Z900 RS has a "tubular" frame type. The difference in frame design may result in variations in handling and stiffness.

In terms of braking, both bikes have double disk brakes at the front. The Trident has a larger front brake diameter at 310 mm compared to the Z900 RS's 300 mm. The Z900 RS, however, has four-piston front brake calipers compared to the Trident's double-piston calipers. This may result in differences in braking power and feel.

Both bikes feature advanced rider assistance systems such as ABS and traction control. The Z900 RS also offers ride-by-wire technology, which may provide smoother throttle response compared to the Trident's standard injection system.

In terms of dimensions and weights, the Z900 RS has a longer wheelbase at 1470 mm compared to the Trident's 1401 mm. The Z900 RS also has a higher seat height at 835 mm compared to the Trident's 805 mm. The Z900 RS is also heavier, with a kerb weight of 215 kg compared to the Trident's 189 kg. However, the Z900 RS has a larger fuel tank capacity at 17 l compared to the Trident's 14 l.

In terms of strengths, the Triumph Trident 660 2021 offers a powerful three-cylinder engine, good chassis and brakes for its class, extensive electronic equipment, and optional quickshifter with blipper. It also has simple and accessible controls. On the other hand, the Kawasaki Z900 RS 2018 has a powerful and smooth engine, good looks, a comfortable seating position, and balanced handling. It is described as easy to ride and not nervous or ponderous.

In terms of weaknesses, the Triumph Trident 660 2021 is criticized for its overly defensive traction control. The Kawasaki Z900 RS 2018, on the other hand, lacks a shift assistant, is heavier than other retro bikes in its class, has a seat that may be too soft for long tours, and lacks wind protection.

Overall, the Triumph Trident 660 2021 and the Kawasaki Z900 RS 2018 are both capable naked bikes with their own strengths and weaknesses. The Trident offers a more accessible and modern package with its electronic features and optional quickshifter, while the Z900 RS provides a more classic and comfortable riding experience.
