The money you pay on mods you are not really going to get back. Including the money you have already spent. Whereas the money spent on a whole new machine will come back to you more.
It depends on what you want. An SV with a radial Gixxer front end, and a nice shock will handle really well. If you are knocking on the door of 80bhp, then, realistically you have enough power. (Enough
). To me, handling is almost everything.
There are other things to consider, like the insurance, and any mods on the bike you are about to buy. Also, a flash bike will be more likely nicked.
I dont know, my plan is to mod up my bike, with shocks and something with the front end. And keep it. It will have next to no re-sale value, so screw it. I know my bike, and it makes me happy. Thats enough for me for the forseeable future.
