Hi
I have ridden lots of modern stuff including a gixer1000k3 on and off track, I run a 749R and feel the Mag wheels make the difference, although heavy (the bike not the wheels) compared to a lot of modern jap sports bikes it still feels lighter through the bends on the road or track.
Obviously the bikes set up makes a difference as do the tyres you use, I guess its a cost thing but do not forget you can always remove them and sell them on after you change bikes and recoup some money.
Slipper clutch I agree make a difference but in real world road riding the benifits are limited. Unlike the lighter wheels which you will feel the difference straight away and all the time (until of course you get used to them and forget you have them fitted).
