Hi K,
Dont know the answer to that, my RG had Spondon chassis so maybe Steve Henshaw decided to hang onto his Spondon calipers to carry over to his MK8.
Just looked at some old pics and my RG calipers were on the front, i think everyone at the time had different ideas about how the antdive worked dependent on whether calipers were in front or behind. Probably a question for Paul MB !!

Calipers in front or behind shouldn't make any difference to how the Suzuki hydraulic anti-dive units bolted to the forks work. The pressure of brake fluid in the line at the top of the ANDF just closes a valve against the pressure of a spring to slow down fork oil through the body of the ANDF dependant on how hard you pull the front brake lever.
However there was always talk about calipers behind forks get too hot, or at least not sufficient cooling air, and that they were stopping the forks compressing because the disc was going up through the caliper. Whereas, calipers in front of the fork legs allowed beter cooling to the pads and calipers and because the discs were going down (ok across) the pad then the forks would compess more.
So, pretty much one of one and one of another adding up to one or 42 or total buls**t.
Of course, a bigger issue may be that by having the calipers closer to the steering axis when they are behind the legs reduces weight out the front to reduce the pendulum effect when you get in a tank slapper. Possibly less pad knock back as well?
Not convinced on any of these I'm afraid but then I didn't have to ride them either! I just thought most, not all, bikes looked better with the calipers behind the legs. You will see if you study the two TR500 piccies that it came to me with the calipers in front and left with them behind. As it's not a standard set up (would have had Cerianis and double twin leading shoe), I guess no-one can say how I've put it together is wrong.
