Is that the bike with 2-wheel drive and tanks in the wheels?
I remember seeing one in Coleman Power Sports in Falls Church, VA over 30 years ago.
Absolutely - I can think of a couple on this board - but it's just like any other piece of safety gear and like practice, it can help when certain occasions arise.Has anyone ever crashed on an ABS equipped bike? Reading this thread, one would think that they are invincible!
So if you lock up both wheels, the ABS will think you've already stopped?My CTX1300 ABS system (don't know about the ST system) does operate by comparing the differential spin between front and rear tires.
Maybe. It's highly unlikely that you would, or maybe could, lock up both front and rear at exactly the same time. ABS sampling happens VERY fast. So ABS would still have another wheel to compare to and keep them both turning. Have you noticed how much, or little, space there is between the slots on an ABS sensor disk? When going down the road at any normal city street speeds those slots are passing the sensor really fast and the ABS system is keeping close watch on the timing between each slot passing that sensor. If you are really talented enough to lock up both wheels at the same time, or at least within a shorter time than the ABS samples, I would expect the system would not respond. But I really don't know for sure about that. And especially since I've not met someone yet that I know of could lock up both at exactly the same time other than when coming to a stop to demonstrate. Part of what I don't know about the system is if the ABS "computer" has a sense of how fast is not normal for a wheel to slow down and stop turning. These kinds of technology are not foolproof and not perfect.So if you lock up both wheels, the ABS will think you've already stopped?
Thanks, that was really useful information. And yeah, I take turns pretty conservatively (haven't scraped anything yet), but the unexpected always seems to happen at the worst possible moment.@ddemair, There is a warning with most vehicles equipped with ABS that addresses the fact that the system cannot help in any way when sliding sideways. ABS will not activate if the wheels are sliding sideways. My CTX1300 ABS system (don't know about the ST system) does operate by comparing the differential spin between front and rear tires. That is also how the same system can be used for the traction control as well as even cancelling the turn signals after a turn (really wide rear tire spins differently than the narrower front in a turn). That last feature is iffy in a really gradual curve so the secondary turn signal cancel system takes over (turn off in certain number of seconds). Anyway, both ABS (and 4 wheel drive in cages and 2 wheel drive in certain special bikes) is useless when going sideways so ABS in a panic stop while in a full lean turn is not likely to turn out well. Yet another reason for standing your bike straight up and going straight if you have to really lay on the brakes in a turn (and also to be very careful to go into a turn at the right speed and entry point to start with). You are mostly right about ABS sensing when the wheel stops spinning. It really is able to sense when the wheel is ABOUT to lock and releases the brake to prevent it from locking up or stopping the spin. As @Andrew Shadow mentioned.
I consider modern systems like ABS, automatic radar braking, and even automatic steering as "helps" but definitely NOT replacements for me paying attention to my driving skills. Those things only exist to help me when I find myself in a situation beyond my own skills or when I miss seeing the hazard. But NEVER to be relied on by themselves so I can be lazy about paying attention to controlling whatever vehicle I am riding or driving.
And yet I know we cannot control everything... obviously.
No. Besides comparing wheel speeds there’s also a wheel deceleration limit programmed into the system. This protects against sudden simultaneously lockup.So if you lock up both wheels, the ABS will think you've already stopped?
