A bike with ABS, regardless if it is front/rear or front only, is probably going to have wheel speed sensors front and back. From what I understand of ABS it isn't triggered by the speed of an individual wheel, it is triggered by a difference in speed between two wheels. In order to sense that difference you need a sensor on both wheels. The way to tell would be to find the ABS pulse module (typically made from a block of billet aluminum) and see where the brake lines coming out of it go.

BMW uses a valve/pump setup. If anyone would of bothered to read the webbikeworld link I posted, you would understand it can and does use the rear brake in it's design.

I will just get the best quote out of that article:

Quote:

Even when using the integral function, the rider has the option to brake the rear wheel harder via the foot brake lever than the integral system as such would allow. This he can do up to the rear wheel locking point where ABS cuts in.

Here's a neat little picture of the brake system with ABS that shows brake and sensor lines running from the valve/pump setup to both wheels.

The bike that we were talking about in the booth was the K1300S HP edition. The GS's are linked - front works front and rear, rear works rear. It's why there is an ABS off button on your left thumb. Essentially, the GS is seen as a dirt option. On dirt you will sometimes want and need to lock that rear.

I was taking my lead on that bike from Sergio - he wrote the technical specs on the K1300...

Gas, I don't understand what you mean about the HD ABS - it's linked or it's not linked?

That sounds famaliar, oh yeah, I been saying the same thing the whole thread................

I don't have any first hand knowledge of the K1300, but the R bikes are pretty much the same system.

Honda's ABS on the Goldwing and the CBRs are pretty close in operation to the R bikes as well.

Basically, there are plenty of bikes out there that do use ABS on the rear.

HD is NOT linked. Not the brake system or the ABS.

You want fun with numbers?

Honda ABS system: 22lbs
BMW R-ABS system [that is on the S1000rr]: 4lbs

I'd rather 0 lbs on a sportbike, as in no ABS, LOL

Stupid Euros with their mandatory ABS policing.

But, it's the easiest bike to do the abs demo on....
