Kawasaki W800. Vertical twin retro, faithfully unchanged.

The W-series traces directly back to the 1965 W1 — itself a copy of the BSA A7. Modern W650 launched 1999, W800 in 2011. The 2026 W800 is mechanically near-identical to the 2011 launch — 773cc air-cooled vertical twin, bevel-driven cams, kick-start removed, twin shocks, chrome everywhere. Direct rival to Triumph Bonneville T100. Marketed as 'the most authentic vintage motorcycle still in production.'

What actually changed.

1996 → 2026 · 30 years of "progress"
Mechanically near-identical to 2011 launch 15 years, minor changes only The 2026 W800's 773cc engine, bore, stroke, valvetrain, frame, swingarm, tank, seat, mudguards, and exhaust are within 99% identical to the 2011 launch model. The only meaningful changes since then: ABS added 2019, slip/assist clutch added 2019, Euro 5 update 2020. Kawasaki's stance is 'don't fix what isn't broken.'
Bevel-driven cams — not even chains 1965 engineering retained The W800 is one of two production motorcycles still using bevel-driven SOHC valvetrain (the other is Royal Enfield Continental GT 650's earlier UCE generation, now retired). Adds mechanical complexity and weight, but produces the distinctive W-series whirr. A deliberately preserved anachronism.
Direct rival: Triumph Bonneville T100 $8,999 vs $9,995 Both bikes are 270° parallel-twin retros (Bonneville is liquid-cooled, W800 is air-cooled). Bonneville T100: 64bhp, 230kg, 790mm seat. W800: 51bhp, 226kg, 770mm seat. The Kawasaki is $1,000 cheaper and lower-seated; the Bonneville offers more performance and modern liquid cooling.
Heritage: 1965 W1 → 1999 W650 → 2011 W800 60 years of vertical twin The W-series is one of motorcycling's longest-running retro lineages. The 1965 W1 was a near-direct copy of the BSA A7 (legitimate, BSA collapsed by then). W650 (1999) was the first Japanese retro built specifically as a vintage-styled bike, predating Triumph's Bonneville revival by two years.
Air-cooled in 2026 — increasingly rare 773cc air-only Most modern parallel twins are liquid-cooled (Triumph Bonneville T100, Royal Enfield 650 twins, Honda CB750 Hornet). The W800 is one of the last air-cooled big twins available new. The cooling fins are functional, not cosmetic — air-cooling is what allows the engine to keep its sound character.
770mm seat — among lowest in 750cc+ class Accessible to short riders At 770mm the W800 has one of the lowest seats in the 750cc+ class. Triumph Bonneville T100 is 790mm, Royal Enfield Continental GT 650 is 793mm, Royal Enfield Interceptor 650 is 804mm. Combined with 226kg wet — heavy but manageable.
