Is there a 500cc or bigger engine that will fit in a v-thunder frame?

Question

how can a 300cc v-thunder motorcycle increse its power and speed if not by changing the engine.

Answer 1

Honestly there is not much you can do to the Vento motorcycles to give them more power. The only thing I do know you can do is to take the baffles out of the mufflers. this gives you a little more performance (not very much) and makes it a little louder, but not too loud. the frames on these bikes wouldn't hold up to a larger engine. they are not welded together good, and would probably vibrate apart.
