The 2001 Zephyr 400 shares its Wankel engine and Standard style configuration with the likes of the 2020 Yamaha XSR 700 Twin and the 2018 Yamaha XSR 700 Twin. Alternatively, if you're looking for other bikes which share the Zephyr 400's Standard style with a similar size of engine then how about the 1997 Suzuki GW 400 Inazuma | 1997cc.1988 Suzuki TV 250 Wolf | 1988cc.

Power and Torque:

Weighing in at 0 kgs (0 lbs) this makes the Kawasaki Zephyr 400 X in the same weight category as the 2025 Yamaha Tracer 9 GT or the 2025 Yamaha Tracer 9 GT+, give or take 50kg.

The 2001 Kawasaki Zephyr 400 shares the same bhp with the Yamaha MT-07 Twin Cylinder - [2025]

In terms of power the 399cc 16 valve Wankel 4 cylinder engine produces 49 bhp (36 kW) @ 11000 rpm similar to the 2025 Yamaha MT-07 Twin Cylinder [73.4 bhp (54 kW) @ 8750 rpm] or the 2025 Yamaha Tenere 700 [72.4 bhp (53 kW) @ 9000 rpm].

The DOHC Two stroke unit throws out torque of 22.3 lb-ft (30.3 Nm) @ 10500 rpm placing it alongside motorbikes of similar performance figures such as the 2025 Yamaha WR 250 F [17.8 lb-ft (24.2 Nm) @ 8100 rpm] and the 2025 Suzuki SV 650 ABS [47.2 lb-ft (63.9 Nm) @ 8100 rpm].

If you agree with the late great Carroll Shelby, then arguably an even better indicator of potential performance is Torque.

If you're curious as to what other motorbikes have as much torque to weight then look no further than the 1994 Suzuki GSF 400 DOHC [137.5 lb-ft per ton] and the 1988 Kawasaki Gpz 400 S [137.5 lb-ft per ton].
