I've got drag bars, stock seat and used to have factory pegs. Wasn't too bad around town, but after an hour or so at highway speeds I found myself sliding my ass around trying to keep my hips from cramping up. (bad deal at 80+) Sooooo, I did the po' boy rearsets last weekend, flipped the pegs side to side (you better have a welder handy to do it right) shortened the shifter about an inch and redesigned the brake pedal. MAN what a difference!!!
It went from feeling OK to feeling "right". My balance is better on it now, I can dive into corners with more confidence (more like attack them
) and keep my line without even thinking about it. It just goes where I look now instead of having to plan out corners waaay in advance and hoping that I come out OK.
But... I think Euro bars or 400f bars are in order. That would get my seating position better and would probably make the bike even easier to manipulate.
There's a reason the late 70's superbikes had "superbike" bars and rearsets. It looks to be the best combination for that type of bike. High CoG, and reatively heavy bikes need the rider higher up to make things happen faster. It also puts your body in a more natural position, right angles at the knees and hips, even if you are leaning forward.
