Whichever the model, the result is a visual treat for fans of classic superbikes. The best thing about AC Sanctuary’screations, however, is that these rejuvenated old warriors are genuinely great motorcycles to ride, with performance that’s radically improved over the originals. It’s no wonder the company has a constant waiting list, despite the inevitably high price of machines requiring many hundreds of hours’ work. And although a genuine Real Complete Machine is financially out of the question for most Japanese enthusiasts, these bikes surely inspire many less ambitious projects along similar lines. The quality and attention to detail make each RCM bike utterly unique, but the basic appeal of a hotted-up classic superbike is appealingly universal.
