We have two 03 Scorpa sy at are house.The step boys rides expert his bike is the race model very quick off the bottum in all the gears.My bike is the comp model but we put the lighter flywheel on and does not stall in the mud and hooks up well.I rode the boys bike a loop at a club event and it felt much quicker then mine and you sure wanted to hold on tight.Had some time on Mikes Komers o4 and it seemed right for power plenty at all times.JR :hat:
