been thinking the same thing, the swingarm will have to be built but almost any fab shop can do that, trips have to be built to the stem. it gets super expensive unless you have machine shop access, even materials are expensive unless you have a 250r donor trike - then your set. id stick with the cbr chasis its just far less work!
