Although it has grown, the format of the Buyer's Guide remains much the same as that in years past. The motorcycles included are listed alphabetically by brand, and within each brand, by price in descending order. We include just those manufacturers that design their own engines, so companies such as Big Dog and Boss Hoss, which use non-proprietary engine designs, aren't included. This is done primarily so that we don't have to take on the large and somewhat amorphous group of semi-custom machines using Harley-pattern engines. We have also omitted many of the small bikes being imported from Asia until they are reasonably well established, as are Hyosung and Kymco.
