After reading up on all the info about the rear ABS problem it was a nice day to try it out. Based on speeds not over 30 mph. On several tries under close to the same conditions. Rear brake was applied deliberately to try a lock up. What happened was there was a noticeable kick back on the pedal. Felt like a tap than any type of condition to shake foot off pedal or cause any major distraction. This condition would repeat at regular intervals and decrease as the speed of bike dropped. At a point of going under 10 mph the tapping faded away. I did notice on several times that the tire did slid a wee bit but there was some fine gravel. But this occurred at about the point the bike was nearly stopped. This was done on residential streets as not to get rear ended on a highway. This is also my first ABS bike. And I did apply brakes as close as done in an advance rider course to apply full rear brake till it locked up and hold till the bike stopped. I believe that my system is working OK. I hope it matches others persons conditions that knows that their system is fully functional. The front bike was not tried in this manner. One thing at a time. That may be done later. There was no ABS warning light. If it was I didn't see it or it was washed out by the bright sun light. Hope this helps those in need of information. Ken Swartz
