Denny, a small expansion on Mikes comment might include that the oversize cylinder after a re-bore might make the volume a few cc bigger. Doug

Denny,
They are actually slightly less than 175; 174.632. But for all practical purposes they are a 175cc motor. Just about every motor is slightly different than the factory designation, they just round it off, much easier for ads and stuff, for instance the 125cc bikes are actually 124.87cc. Can you imagine the big factory announcements for the '48s?; "Come in today and try the all new Harley 124.87!"

I just listed by 62 Scat and the catagory came up as Scat 177 CC. Are they 177 or are they 175? Thanks for whatever info you can provide.
