The smaller brother of the flagship R1, the 1999 Yamaha YZF-R6 is an equally enthralling bike. Packing a 599cc displacement for its 4 in-line engine, it is capable to produce a peak power of 120 hp and 92 Nm of torque. The power to weight ratio is lower than that of the R1, as the R6 tips the scales at 169 kg.
Nevertheless, the 1999 R6 is no to for inexperienced riders, as it has been loaded with state-of-the art technology, and is an adversary to be reckoned with both on the track or on the street.
