I had gpsed it at 48,but it had more in it.It was a little monster,with wheelies at will.If I had been willing to lose a little power,or loosen up the slipper more it should be fine.It's just kinda hard for me to compromise those things as a hard basher.All said and done I am very happy with it.My new shafts will hopefully be in on Friday,I'll slap some Talons on it and see what happens.
