One of the big challenges a custom builder faces is keeping the bike he or she is building clean. Each component added to a bike creates a potential eyesore; none is worse than a throttle cable flopping around the right side of your bike.
There is no question that an internal throttle cable is clean, but not everyone knows how to install one. We happened to be at Jim Nasi Customs in Scottsdale, Arizona, as the staff was prepping a bike for such an install. Nasi and his crew specialize in building custom handlebars with internal throttles, so getting them to go through the steps involved for us was easy.
