I built a really bad azz, electra-glide, I'm really, really.... bad, second gear wheels up, as soon as I was almost finished with it, someone gave me all the money I had in it, for it, about 40k. it was scary to ride sometimes and leaked oil from the extreme compression from day one (this is something I didn't like). I went into the dealership after the sale and saw the 2009 Yellow Pearl SERG, figuring I would just by a brand new bike and modify it a little.... once again. The dealers had begun to let you ride the bikes that you were thinking of buying, especially if you had cash, and I rode the SERG.....end of deal, no buying a regular bike and customizing it and it still being worth what a stock one was, I got lucky one time and the performance on these 110 are respectful right out of the box, I've still done quite a bit to the SERG, but have left the internal components alone with the exception of the cams and some light port work......man I'm in Heaven
