Engine architecture
V-twin → Parallel Twin
Every Kawasaki cruiser before 2015 was a V-twin (Vulcan 750/800/900/1500/1600/2000). The Vulcan S broke that pattern with a parallel twin from the Ninja 650 / ER-6 platform. Cheaper to build, lighter, easier to package — same logic that drove Honda Rebel 1100 and Triumph Bobber to parallel twins.
Power similar
−3bhp
64bhp Vulcan 1500 → 61bhp Vulcan S. Modern Kawasaki cruiser actually makes LESS power than the 1996 flagship. But it weighs 67kg less, is A2-restrictable, has ABS, and costs less than half in real terms. Different bike, different mission.
Real cost change
−$13.2k
Vulcan 1500 was $11,475 in 1996 ($22,950 today). Vulcan S is $9,719 — about 58% cheaper in real terms. Kawasaki priced the Vulcan S as the entry-level cruiser, deliberately. The cheapest mid-capacity cruiser on the UK market by some margin.
Ergo-Fit innovation
Adjustable cruiser
The Vulcan S launched with Kawasaki Ergo-Fit system — three different seat heights, three different reach options. Same bike configurable to fit riders from 5'2" to 6'2". First mass-market cruiser with this approach. Particularly important for shorter riders (often female) who struggle to fit traditional cruisers.
Why the V-twin Vulcans died
Emissions + market
Kawasaki killed the Vulcan 900 and 1500/1600/2000 progressively from 2014 onwards. Two reasons: emissions made the carbed/early-FI V-twins uneconomic to update, AND the cruiser market was shrinking. Same trend that killed Honda VTX, Yamaha V-Star, Suzuki Boulevard. Japanese V-twin cruisers are essentially extinct in 2026.
Weight loss
−67kg
296kg wet Vulcan 1500 → 229kg wet Vulcan S. Massive weight loss going from V-twin to parallel twin. The Vulcan S is one of the lightest cruisers on the market — easier for new riders, easier to manoeuvre at low speed, easier to hold up at lights.
Cheapest way in
$3.4k
A clean Vulcan 900 from 2006-2012. Kawasaki best mid-size V-twin cruiser, belt drive, comfortable, indestructible. Different bike to the modern Vulcan S — but if you want a V-twin Kawasaki cruiser, this is the cheapest way to get one in 2026.
