Z750 → Z800 → Z900 evolution
Continuous 2004-2026
Z750 (2004-2012, 748cc) → Z800 (2013-2016, 806cc) → Z900 (2017-present, 948cc). Each generation grew capacity, kept the inline-four character, sharpened styling. The Z750 was the original; Z900 is the current. 22 years of the same general platform.
Why Z750 → Z800 in 2013
Euro 4 + sharper styling
Kawasaki replaced Z750 with Z800 in 2013 to address Euro 3+ emissions and to refresh styling for the 'Sugomi' design language. Same general philosophy, larger engine, more aggressive looks. Z800 only ran 4 years before Z900 took over with the larger 948cc engine.
Real cost trajectory
−4% real (vs Z900)
£5,899 Z750 in 2006 (£9,900 today) → £9,549 Z900 in 2026. Roughly flat in real terms. Modern Z900 has cornering ABS, traction control, ride modes, full LCD — significantly more rider aids. Used market in 2026: Z750 £2.2-3.5k, Z800 £3.5-5k for clean low-mile.
ライダーエイド数 (2004 → 2026)
1 → 6
Z750 (2004) had FI as the only rider aid. Z800 (2013) added ABS standard, slipper clutch. Z900 (2026) has cornering ABS, FI, traction control (KTRC), ride modes, full LCD, slipper clutch. The mid-naked class has shifted from minimum-viable to fully electronic.
最安の入口
£2.2k
A clean Z750 from 2004-2008 (Gen-1). 104bhp inline-four, naked roadster, A2-friendly with restrictor. Pay attention to fuel pump (early bikes), reg/rec, fork seals. The cheapest path to a 100bhp Kawasaki on the UK used market.
vs Z900 (2026)
More everything
Z900 (948cc, 124bhp, 213kg wet, full electronics) vs Z750 (748cc, 104bhp, 202kg dry, no electronics). +20bhp peak, sharper styling, modern rider aids. But Z750 is £6k cheaper used. Trade-off: pay more for modern; pay less for older but proven.
Why riders love it
Honest mid-naked
Z750's appeal: inline-four character (rare in 2026 mid-naked class — Z650 is parallel-twin, MT-07 is parallel-twin, SV650 is V-twin). Z750 is one of few inline-four mid-nakeds you can buy used at £2-4k. Cult bike for inline-four enthusiasts.
