Does anyone on here know the range of horsepower and engine weights that can be used on the 1650R?
I have decided to build one, instead of the Hummel H5, as my first build.
There are several engine options I am looking at: Rotax 503, half VW, one of the BMW bike engines, to name a few. The BMW boxer engine looks interesting, because nothing has to be done to the engine itself, but I am concerned about the weight. How would a ready-to-run BMW compare with the other two?
