Modern Vespa

This is a compendium of modifications, grouped by type. Note that some of these items are listed under Installing Accessories, and vice versa. Not all accessories require modification, and not all modifications are really an "accessory", per se. As a general rule, if it's something that just bolts to the bike, it's probably not a modification. If you have to drill, cut, hack, or otherwise mutilate the bike in some way, it probably qualifies as a modification.
