Some early designs have more studding in the seats and saddlebags. The Suzuki Boulevard V50 is made in both standard and “tourer” form, with a windshield, white wall tyres (phased out over the years) and side bags. It’s an evolution of the VL800 Volusia that Suzuki made since 2001, but it was re-named (and re-styled) in 2005 - and got fuel injection to boot.
This is the maintenance schedule and associated service intervals for the Suzuki Boulevard C50, a middleweight cruiser that Suzuki has been making since 2005.
