Just don't be overzealous on the brake tests at lower speeds, until you know what to expect. These bikes (ABS or not) have very strong brakes. I would suggest a series of stops with increasing pressure to get used to them.So what is the safe way to do that?
If you apply a death grip on the handlebar lever at 15 MPH on dry pavement, it will bring you to a complete stop...very quickly. I would describe it as fairly harsh, and very abrupt. This might lead to a tip-over, if you are not prepared. The handle bar lever applies both front and rear brakes.
Jamming the foot pedal at 15 MPH will feel strange. The foot pedal only operates the rear brake. The ABS will kick in and braking will be limited, and there will be some clunking as the brake catches and releases. You won't skid, and braking will feel vague.
On the other hand, a panic stop from highway speed (65+ MPH) is just awe-inspiring.
If the ABS is working correctly, the start-up should go like this:
Watch the two small dummy lights on the instrument console, as you turn on the key. You must not hold either brake at this time. If you do, the brake system cannot complete its diagnostic test. The brake lights are the two bigger red ones that are side by side. When you turn on the key, the dummy lights will turn on and the ABS light will flash at 4hz for a second or two.
The other light should go out pretty quickly. If it does not, there might be a weak battery, or burned out bulb.
The ABS system will complete its test, and the flashing ABS light will slow down to flash at 1hz. Then, it is time to start the bike. Feel free to use the brakes now, too.
The ABS light will continue to flash slowly until you pull away. After you reach about 3-4 MPH, the bike will finish the test of the wheel sensors and the ABS light should stop flashing. If either light remains lit or is flashing, there is some sort of issue.
