Wassup guys Ive been thinking about getting a gear up on my zip 70 becuase Ive been doing more longer distance rides recently and been using more longer faster roads and duel carrageways, and I think a gear up will help as I can only cruise at 45-50mph, 60mph flat out.. But I would like to be cruising at around 55mph. And what gear up would be most suitable primary or secondary? Do both primary and secondary kits have to be pressed in?
