That's a long time and small boys grow up. Well In Germany there is a technician wich raced with the MC 65. Marc Haftka is known as a great (spanish) GasGas fan and dealer. He has made work (together with Oerlemans in the Netherland) with the MC 65. People who still want to get any wisdom about the MC 65 should contact Marc Haftka

A very nice person and a lot of knowledge about the 65. If i had the money then i would have got the programmable ignition for the bike. which made it a lot easier to ride for the little fellow. Anyway after a EC125R he's now riding a GG EC300 '18 and completly happy.
