Pros and Cons in comparison

Pros and Cons in comparison

Kawasaki Vulcan S 2021

Kawasaki Vulcan S 2021

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.

Triumph Bonneville Bobber Black 2020

Triumph Bonneville Bobber Black 2020

The Triumph Bonneville Bobber Black was the sportiest in our bobber comparison. The two-cylinder has more than enough power and sounds more potent than the other bikes, even with the standard silencer. The chassis is also sporty and comfortable and stands out from the Bobber competitors. Our test riders were particularly impressed by the Lady in Black's extensive equipment, such as disengageable traction control, cruise control, adjustable display, and the successful bad boy look, all in black. The Englishwoman was particularly convincing with its powerful, cultivated engine. With its Brembo double-disc brakes, it decelerates well and the Showa fork responds sensitively. Our testers had different views on the seating position and the positioning of the footrests. Zonko in particular was enthusiastic about the position of the footrests. He liked it much more than the more forward position of the other bobbers. Horvath and Juliane would not have objected to having the feet placed a little further forward for a little more lean angle freedom. The footrests scrape extremely quickly and even though we tried it - in many curves it simply could not be avoided. What we therefore unanimously find particularly great is the adjustable seat, which can be moved within less than a minute. This allows the rider to cruise either further forward and more sporty or further back and thus more relaxed.
