Physically smaller although i think that the vertical drop on them is somewhat lower..fractionally . i have a pic somewhere im sure of a close up of the rear. I'l upload it if i can find it.
here it is.. taken at the motorshow this year, or was it last i cant remember..
These are remus exhausts with Touratit pannier frames.. personally i have scorpion exhaust which fitsmuch the same as the remus but only one can (sounds better too and half the bleedin price) which led me to H&B frames which have an angled cross member as opposed to the horizontal one shown.
