The engine is an excellent choice, will make a good MB. I dont think you will have any trouble mounting the kit. There is no gear box, it is direct drive(through an auto clutch) It will not be excessively top heavy, after a bit of riding you wont notice its there. You can have this kit installed in 1-2hrs tops. You will be able to transfer it to another(most) bike in a 1/2hr. Its jut not a hard kit.. I mounted a similar kit to a 24" MTB(there is a thread) with a very narrow frame spread, with no problem. The bike you are looking at is very nice and to an extent over kill for an FD, but if money is no object, go for it.
