Triumph Trident 660 Vs Kawasaki Z650RS Spec Comparison: What's different

Both the Triumph Trident 660 and Kawasaki Z650RS offer retro-inspired styling paired with modern performance. While they compete in the same middleweight roadster segment, the two bikes take different approaches in technology, engine character and equipment. Here's a detailed specification comparison to see how they stack up.

The Triumph Trident 660 is powered by a 660cc inline three-cylinder engine that churns out 79.8 bhp @ 10,250 rpm and 64 Nm @ 6,250 rpm. On the contrary, the Kawasaki Z650RS is powered by a 649cc parallel twin engine that makes 67 bhp @ 8,000 rpm and the same 64 Nm @ 6,700 rpm. Both motorcycles come with a 6-speed gearbox and a slip-and-assist clutch. However, the Trident 660 gets a Triumph Shift Assist quickshifter as standard, offering clutchless upshifts and downshifts, a feature not available on the Z650RS.

The Trident 660 uses a tubular steel perimeter frame with Showa SFF-BP 41mm upside-down forks and a Showa monoshock RSU. Suspension travel is 120 mm front and 130 mm rear. The Z650RS also runs a tubular steel frame, but with a more basic 41mm telescopic fork and horizontal back-link rear suspension, offering slightly more front travel at 125 mm.

Triumph Trident 660 comes with dual 310 mm discs and Nissin 2-piston calipers, while Kawasaki Z650RS comes fitted with dual 300 mm discs and dual-piston calipers. Both use single disc setups at the rear. Tyres differ as well: the Trident uses wider 180/55 R17 rear rubber, while the Z650RS runs on 160/60 R17. Both bikes come with 17-inch cast alloy wheels.

The Triumph Trident 660 and Kawasaki Z650RS are closely matched in size, with minor differences. The Trident 660 has a seat height of 805 mm, a wheelbase of 1401 mm, and tips the scales at 190 kg (wet). On the other hand, the Z650RS has a slightly lower seat height of 800 mm and a longer wheelbase at 1405 mm, while weighing in at 192 kg (curb). Despite the small variations, both bikes are compact, rider-friendly, and suitable for urban as well as highway riding.

The Trident 660 stands out in terms of rider-focused technology. It comes standard with optimised cornering ABS and traction control, a slip and assist clutch, three riding modes (Sport, Road, and Rain), and a TFT display integrated with the My Triumph Connectivity system. This offers turn-by-turn navigation, phone and music control, and even GoPro operation. Additionally, features like cruise control and a bi-directional quickshifter (Triumph Shift Assist) elevate its electronic package. In comparison, the Kawasaki Z650RS takes a simpler approach with fewer electronic features. It does not offer riding modes, connectivity functions, or cornering safety aids, sticking to a more traditional analog experience.

The 2025 Triumph Trident 660 is priced at Rs 8.49 lakh (ex-showroom) and is available in four colour options. On the other hand, the Kawasaki Z650RS is priced at Rs 7.20 lakh (ex-showroom) and is offered in a single colour.
