Pros and Cons in comparison

Kawasaki Vulcan S 2020

No matter which platform Kawasaki puts the 650 cubic two-cylinder in, the result is always a great motorbike! Even though the engine is unusually rev-happy for a cruiser, it results in a cruiser that actually qualifies as a sports cruiser when paired with the sporty chassis set-up. The only brake is the limited lean angle clearance, but this will not deter lovers of hearty footrest grinding. With such a good bike, we hope that Kawasaki will follow suit - after all, the Vulcan S has been with us almost unchanged since 2015.

powerful engine

chassis tuning with sporty Kawasaki DNA

real cruiser seating position

easy-to-read display

potential in tuning

Appearance a little outdated

Triumph Bonneville Bobber 2021

The Triumph Bobber 2026 is the quiet queen of coolness. It doesn't need top values to shine, but shines with composure, torque and mechanical honesty. The Speedmaster counters this with the same genes in a different body: more comfortable, more majestic, with clear limits to the sporty radius. Together, they make a pair that you won't think of leaving the garage once you've ridden one. For soloists who want to breathe style, it's the Bobber. For connoisseurs seeking wide horizons without haste, it's the Speedmaster. And for all those who have both, the common denominator has finally been found.

bobber comfort limited on long days
