More importantly, the sweep of the Yoshimura’s header pipe as it leaves the cylinder is not only the best-looking I’ve seen, it’s also more compact and better angled than some of the alternatives, meaning that if I hit something from the front, it’s less likely to do any serious damage to the pipe and cylinder head. A high-level exhaust would put the end of the can out of any water, but I don’t think I’ll be wading much on this. Obviously I’m not going to be riding this bike over the kind of terrain the real Africa Twin can tackle, but I do intend to explore green lanes on the little machine. While Yoshimura only produces high-level systems for the previous model, there are others available, and it is possible to fit a high-level to the new bike, with some modifications to the underside of the tail to hang the can from. As such, it might seem odd to have chosen a low-level pipe. I’ve fitted it to my project Africa Grom, which is a tribute to the Africa Twin. Yoshimura’s RS-2 is one of the most popular premium-quality exhaust systems, and is claimed to give increased performance with no fuelling adjustments. This is far from a cheap bike, costing £3,349, but ride one, as there’s a good chance you’ll understand why even experienced bikers suddenly discover a desperate urge to find space in their garage for a ‘Mini-Street Xtreme’.
