ok, I spoke to dad, he says that is the way they put the bike together, sprocket to sprocket. It never gave any problem at all within the drive train, every bike with the Ossa motor was like that out of square
He tells me,the blue bike was the only true Alron, with their own built or remanufactured Sprite frame, so that the motor sat straight etc.
Now what gets me is the number of times we think of putting a motor in a different frame, but doesn't sit straight. hey guess what it doesn't matter what angle the motor is at as long as the sprockets lineup
