💡 Technology Features

Instrument Cluster:

Digital LCD instrument cluster featuring speedometer, tachometer, odometer, trip meter, clock, fuel gauge, and indicator lights.

ABS Availability:

Optional ABS on certain models/markets. The 'SC' designation usually implies standard features for that year's offering, but ABS confirmation is specific.

Connectivity Features:

No advanced connectivity features such as Bluetooth or smartphone integration on this model. Focus is on core motorcycle functionality.
