Totally normal. There is a self test procedure that is completed by the ABS sensing both front and rear wheel movement and then it completes and shuts the lights off. They should both be blinking at the same time and go out. An alternating flash or just one of the lights would mean some issue is present.

Re: abs light

Ha Ha yes it's a bit like a German sense of humor. Turn the bike on and you get a message that says break failure. It amuses me every time, especially if someone else sees it.
Only worry if it stays on. But then in the 40's they also had a strange idea for a European vacation.

Re: abs light

I read somewhere that the lights go off at 3mph as the test needs to detect that the front and rear wheel sensors are matching.

Still rolling in Southern Oregon

Re: abs light

Just be aware there are two phases to the self test. First there is an internal self test where the lights flash rapidly. This usually completes in a few seconds, UNLESS you are applying the brakes when the key is turned on. If you do that they will continue to fast flash until you release the brakes. Once the brakes are released the internal test will finish and the lights transition to the slow flash. All internal testing has completed at this point and it is waiting for wheel sensor input. Once you roll a few feet that test will complete and the lights will go out.

To avoid messing with the internal test at key on, while on a slope, just leave the bike in gear to hold the bike and then once it transitions to slow flash you can apply the brakes and either pull in the clutch or shift to neutral to start the bike.

John and all,

I believe the OP (wingnut789) has created confusion by omitting to specify what year K1200LT he has in EVERY question - a very common problem here on our forums.

Based on a quick search of his earlier posts, it appear he has a 2000 model, THUS he does NOT have integral-ABS with servos. Instead he has earlier system called ABS2 that is simpler (seen in 1999-2001 models for USA market).

(1) He should keep in mind that these ABS2 will flash both warning lights at same speed after ignition ON if basic initial checks are OK. Of course, these also need your bike to move up to certain speed before the system can confirm that both ABS wheel speed sensor are responding equally on both wheels.

(2) IN CASE the basic initial self-checks are NOT OK (just after ignition ON), these ABS2 system will flash both warnings in alternate fashion - this is often referred in forums as the "Wig-Wag" or "WigWag".

(3) some warning may also be caused by low battery voltage, so it is always suggested AFTER IGNITION ON, to wait approx 5 seconds before you press the stater button. This will give a change to the ABS internal self check to proceed with max amount of voltage available

(4) Contrary to later Integral-ABS system, on these ABS2 systems. the fluid level of all reservoirs is NOT monitored and no warning will appear in case of low level (either handlebar master -OR- rear round reservoir above footpeg)

P.S.: OF COURSE, I am fully aware that John knows these differences between ABS2 and Integral-ABS, I am just including them for the OP who appear unfamiliar with his own system for a 2000 year K1200LT.
