Servus and Happy Easter First time data of the scooter: Kreidler Hiker 125 RMC-E DD Sport Year of construction 2009-2010 Jup a rather rare model. KM 4622 used bought with 4512 km Was driven only short distance (max 3km) Following questions My biggest problem is the performance loss the mountain high. OK I have 100kg but from to 80kmh to 60 kmh and if really steep then down to 50. Not exactly enthusiastic. In addition, the scooter does not get over 5000u/min when I sit on it and No matter if mountain up or on the straight. On the straight he managed his 80/85 kmh was enough for me….if he would also make it up the mountain. I still have an old 50 Speedfight 2 LC with 35000km on the clock and about 3hp. The more steam was filled on it. I also find my 100kg pulling better through the area. I made after the purchase. ÖL changed Varioweights…the old ones were more angular than round. According to Internet 13g….Unfortunately no better information was found. Kickstarter was fixed…cleaned and he went again. Coupling was just cleaned… there was viiiel abrasion/dust in it. Gear oil replaced. V-belts replaced. Built-in was an 842x20x30 Internet spooked out n 835x20x30. (building feeling says that I should install the 842 possibly to remain true to original) Engine is a 152QMI-1 air filter I blew out once. Petrol filter looks good. A new spark plug is also in it. So that’s what I put together there. ch on tips and tricks… and say thank you and Merce Greets Chris
