Handlebar Adaptor Question

Hi, I'm looking for suggestions on what handlebar adaptor to get for my 2002 Derbi GP1 50. I was thinking of getting a "TNT Adaptor for 'downhill handlebar' GILERA/PIAGGIO" (http://www.sip-scootershop.com/Produ...+downhill.aspx) but I'm not 100% sure it would work with my scooter and thought I would ask to make sure.
