just got done with an install,bought a so called 80 (z280)from the guy I got my last one from.I am impressed!!! it seems that they got it together at the factory!! Really,the quality is there and the price was right.my first ride I could feel the difference in vibration and power plus the added doo dads like a BB tensioner and nice grips that arent stuck to the styrofoam .Also Rick answers all my emails and questions,If we have an issue he resolves it quickly.
After break in I may choose a different bike to mount it on but for now my schwinn skyliner continues to get me to work and around.Kudos to Rick at BGF,I like the Z280!!
