Hey folks, are the brakes on the CBs linked with the ABS option or is just the ABS feature combined? does combined mean that both fr and rr work together in the anti lock mode only..I hope you understand what I am trying to ask..LOL.
I believe the ABS have linked front and rear brakes. I read somewhere when applying just the rear brake it slightly activates one piston on the front calipers for the combined effect. I do not think it matters if the ABS is engaged or not.
The C-ABS is the same (although vastly improved) design as the much maligned CBS (Combined Braking System) which was pioneered in racing and later featured on the GL1200 (1982) and later the CBR1000 in 1993.
The system does indeed operate both brakes despite the rider only applying one. Having only ridden one other bike with linked brakes (a CBR1000 in 1996) I was a little perturbed when I first used the rear brake on the CB1100 a few weeks ago when I collected it. The front brake lever actually moves in a touch when you push the rear brake pedal. I felt myself pushing it away with my fingers but I've got more used to it now.
It's a little like those old pianos that they had in the Laurel & Hardy films which would play themselves when they walked away from them, and the keys depressed as if by magic.
As I'm still in the running in period, I've not given the system any abuse to attempt and 'intervention' but I can say the brakes are bloody fierce, and haul the bike up in short order! They do however have plenty of feel and are very confidence inspiring.
I think the ones on the UK bikes (which all have the C-ABS) are lifted off the VFR whereas the US models without ABS use a setup from an earlier Fireblade (CBR1000RR).
To be honest I'd have been happy to have the non ABS version and save some cash and potential future repair hassles but it wasn't an option.
IMO linked brakes exist because riders aren't trained to use the front brake properly. In a "panic" situation, the tendency is to slam on the pedal, like in a car. Linked brakes mitigate the danger of locking the rear wheel, or if in a curve, standing up the bike and riding off the road. There's nothing wrong with the feature if it saves someone a wreck, but it would be better still if we had more extensive rider training to go along with it.

I think it is all the time with the pulsating kicking in on panic stops. I have non-abs so I can't test it.
I remember seeing a video of Honda engineers testing the ABS system on the CB1100 some time back. It did not appear that there was any noticeable pulsating involved when the ABS kicked in.

There isn't, you're right. It just stops like a pro. No drama, no warble.
The rear petal does pulsate if you try to lock up rear brake I tried it. Not sure about front lever but it would have to pulsate also not to lock up

This a linked brake system non abs.
The CBR1100XX and VFR800 featured what Honda called LBS II (now called Dual CBS), a system where both levers would activate both brakes through a system of secondary pistons and proportioning/delay valves.[7] One front brake caliper was connected to a secondary master cylinder, and the caliper was allowed to rotate slightly to apply pressure to the piston in that secondary master cylinder. Braking force was translated into pressure that was sent to the rear brake cylinder. Only the two outer pistons in the front brake calipers were directly activated by the brake lever; the center piston received pressure from the rear pedal via the proportioning and delay valve.
The C-ABS which is on the CB act in a very similar manner only that it apply braking to both calipers.
This system took some time getting use to on my XX, it will stand you straight up when braking hard in a turn. Try it and get use to it so if and when it happens you have a feel of what the bike is going to do.
Edit: A great example is shown in a video a member posted last year when he anticipated a SUV making a turn and went hard on the brakes.
"Combined ABS" as is used on our (equipped) CB1100's and my VFR1200F, will apply front braking, if you use the rear pedal only in a panic situation. It will not activate any rear braking if you use the front brake lever only.
The linked braking system on my ST1300 will apply back brakes if you use the lever only, and it will also apply front brakes if you use the pedal only.
Honda's linked/combined braking systems seem to be always changing/evolving/advancing.
