What started in the mid-90s when a few people decided to build (stock Softails÷ from aftermarket parts·because they couldn’t buy one at the dealer·has evolved into a full-blown industry. Today, every small town has a Chopper or Custom bike shop and every cable TV channel has a Biker Build-Off series. No longer content to build copies of stock motorcycles, today’s builder wants a motorcycle that’s longer, lower, and sexier than anything approved by a factory design team. Wolfgang Publications and Tim Remus were there at the very beginning of the trend with their Ultimate V-Twin Motorcycle book. Today they’re back with their new book, Advanced Custom Motorcycle Assembly & Fabrication. Part catalog, part service manual, and part inspiration, this new book offers help with planning the project, getting the right look and actually assembling that custom bike you’ve dreamed about for years. Three start-to-finish sequences show not just how the best bikes are bolted together, but how the unique one-off gas tanks are shaped and then covered with candy brandywine paint.
