2021 Suzuki DR-Z400SM MC Commute Review

A review of Suzuki’s tough and street-legal supermoto in the 2021 DR-Z400SM.

Budget-minded riders that want to have urban fun, without breaking the bank will appreciate Suzuki’s DR-Z400SM. Built around Suzuki’s tried-and-true DR-Z dual-sport bike, the SM version trades its dual-purpose off-road setup for a road going configuration for those who want to slice through traffic and carve corners on the weekend. In this episode of MC Commute we swing a leg over Suzuki’s purposely retro street-legal supermoto. Tune-in and see what it’s like to ride.

Suzuki continues to offer its affordable $7,499 DR-Z400SM street-legal supermoto bike for US consumption.
