Hi mate I have a MPL aftermarket slave on my RSVR factory (already fitted when I bought the bike) and had the standard one on my previous bike (a first generation tuono) and to be honest there's not much difference between the two! My tuono was a ***** to get in to neutral and so is my factory! the easiest way is to put it in second and knock it down in to neutral, exactly the same as my tuono so it looks like to me it's not worth upgrading unless the bling of a fancy slave cylinder appeals!
