Suzuki have presented details on their RM-Z250 and RM-Z450 motocross bikes for 2021 ahead of their Australian release in December.
Both are largely unchanged from the current model, with the usual graphics changes, but the latest version of Suzuki’s MX-Tuner 2.0 tuning device, previously available only on the RM-Z250, is now available on both the RM-Z250 and RM-Z450 for 2021.
The MX Tuner 2.0 allows engine mapping to be altered via the intuitive smartphone WiGET app, available for iOS and Android devices.
Four pre-installed and factory-developed maps are included in the WiGET app - covering ‘Aggressive,’ ‘Smooth,’ ‘Richer,’ and ‘Leaner’ - to make tuning for different riding styles and track conditions easy.
Using the MX-Tuner 2.0 and WiGET app, power delivery can be altered to a softer response to suit hard packed surfaces or maximum power for deep, loamy conditions and drive out of the corners.
More experienced tuners can create their own fully customised maps with specific settings across a total of 36 points of ignition timing and 36 points of fuel injection delivery.
The MX Tuner 2.0 can also be used as a maintenance record. Selecting the tuner’s service tab to see the hour meter reading, or add a maintenance log to record when a particular component has been serviced, such as completing an oil change
Major componentry for both models carries over unchanged, with the 249cc and 449cc singles in both models unchanged, as is the 5-speed transmission.
Both 250 and 450 RMs retain the Suzuki Holeshot Assist Control that offers two settings, selected via a handlebar-mounted switch, and can be deactivated. A” mode is programmed for hard surfaces, such as a concrete starting pad, clay or hard-packed dirt where controlling wheelspin is crucial to good starts. The “B” mode is for normal dirt conditions.
The RM-Z250 retains KYB suspension front and rear, while the RM-Z450 continues with Showa shocks at each end.
Nissin braking remains, made up of a 270mm front wave disc with two-piston caliper and 240mm rear wave disc with single-piston caliper.
The aluminium twin-spar frame and 6.3-litre fuel capacity in the lightweight resin tank carry over unchanged, while the Renthal Fat Bar handlebar and black anodized Dirtstar rims remain in the standard equipment list.
The 2021 Suzuki RM-Z range will be available from December, with recommended retail pricing of $10,790 ride away for the RM-Z250 and $11,690 ride away for the RM-Z450.
