The big Burgman is the seminal maxi-scooter, and still has the edge over the AK550 in terms of power and torque, but only just. Its 638cc two-cylinder, liquidcooled, DOHC engine produces 54.3bhp (40.5kW) @ 7000rpm and 45.7lb-ft (62Nm) @
5000rpm. But it’s also heavy at 277kg (wet) and pricier than the Kymco. Given that the Burgman 400 got updated last year and the big 650 has been unchanged for a while, there might be an update coming from Suzuki soon.
