I had a streetfighter magazine fro several years back where the cover bike was a sv650 with tl1k engine in it and it took some fabbing and never looked right. Had to move motor mounts and the whole thing looked "off" even for a streetfighter. SV1k's aren't super expensive used and my brother was thinking of getting a sv650s but bought a sv1000 naked because it was about $1k more than a 650


or just go buy a tl1000s instead....they're fairly cheap and I have seen several gorgeous examples for under $4k
