I've got a 2016 cb500f and I love it, been riding dirt bikes for about 14 years and I've only been on the street for 2 so I picked up a cb500f because I loved the look. However, it is lacking in power. I was wondering if possible when the bike is paid off, if another engine would fit in the frame. I was thinking a duke 690 or husqavarna 701 engine would fit because they're both parallel twin engines, don't say get a bigger bike because due to some loop hole my insurance on this bike is next to nothing. Plus I love the look and design, any thoughts from y'all?
