I'm the Dutch testdriver for stage6 and i can tell you that stage6 did take part in developing this shocker. Ofcourse the basics are the same, but stage6 did change some of the settings/products that are used in the shocker so it's specialy customaded voor racing with scooters. That's why they wanted to have feed back from the testdrivers so they can change things that aren't good before they will put it for sale.
I can tell you that the stage6 shocker passes the RS24/10 by far if we talk about the price/quality difference. it's a real good shocker for racing use, maybe a little to stiff for the streets.
I have a Malossi RS24/10 set either, the rear suspension costs about 500 to 600 euro. I brought it to a specialist, he said it was crap so he assembled a progressive spring and changed some settings(that costed me 100euro extra). So for 600 to 700 euro total the RS24/10 was becoming a better rear shocker. I compared it the two shockers on the same track, and now the malossi RS24/10 fine tuned was as good as the stage6 shocker coming out of the box.
So...if you ask me...when you buy the stage6 shocker for 370 euro you will have a better shocker for almost the half of the money.
