ABS and Non ABS Calipers

Can anyone help with definitive information on ABS and non ABS calipers as to whether, or not, they are different?

Does the non ABS bike have the inter-connected front and rear circuit which would make the front caliper a three pot caliper like the ABS bike?

I guess you would have to define different.The calipers are the same as far as function. I'm sure someone will correct me if wrong but when apling the left brake lever 80% stoping power is to the rear brake 20% (goes to the center piston)to the front. The right brake lever gives 100% to the front. Honda does show a different caliper on ABS brakes because they service the hole assembly (brackets etc.) on there caliper.I think the subject of changing to ABS brakes on a non ABS system has been brought up before and is not practical . The answer to your second question is yes. Howard

I guess what I'm really asking is, are the pistons the same size on non ABS calipers as they are on ABS calipers, and can the calipers be swapped.

I'm not trying to put ABS on a non ABS Silverwing.

I'm in need of front and back calipers for an ABS bike and since I can't find them I naturally considered the possibility that non ABS might be the same apart from the front sensor for the ABS ring on the wheel.

Donie the piston part numbers are the same so they should be the same part. Below are links to the drawings, that's the best way to find out if parts are the same.

Thanks Roger and Howard for your help.
