Traditional, full carbon exhaust system with oval shape, but a modern end cap. The full carbon exhaust system of course has an advantage over other exhaust systems, mainly because of its feathery weight. But let's be honest ... Who cares about the weight? Here it's all about the fact that the exhaust system on the YZF-R, as well as the MT 125, simply looks like porn. Not to mention the sound of the exhaust system! Nevertheless the exhaust system does not look too obtrusive. Neither the sound nor the look seems overloaded or unpleasant. Due to the included, firmly installed catalytic converter, no problems with the Leo-Vince LV-One are to be expected, even during an inspection or the TÜV/AU.
