No, most older motorcycles do not have ABS (Anti-lock Braking System). ABS is a safety feature that helps prevent the wheels from locking up during braking, allowing the rider to maintain control of the motorcycle. It became more common in motorcycles starting from the late 1980s and early 1990s, but it was not a standard feature on all models until more recent years.
If you're considering purchasing an older motorcycle and you specifically want one with ABS, it's important to research the specific make, model, and production year to determine if ABS was available as an option or standard feature. Keep in mind that ABS technology has improved over time, so the effectiveness and performance may vary between older and newer systems.
