Λιγότερα άλογα άλλα ίδια ροπή, με 220kg

Yamaha Fazer8 will be the version of the half fairing naked FZ8 (see details below) with 800-cc engine and chassis derived from those of the FZ1. Plastics Fazer8 they will increase the weight by 214 kg of naked about 220 kg. For the rest of the half fairing will be identical to the naked. Looking at the design, especially the front, there is a certain similarity with other bikes Yamaha family and especially with the double flagship YZF-R6, but also with the style lines of the FZ1 half fairing, the FZ1 Fazer .

FZ8 New FZ8 has well over something in common with the FZ1, which takes up the same cycle and hence the engine, it seems, is reduced nell'alesaggio and will surely lower performance. At first glance, the new three tuning forks, compared with the FZ1 you notice the exhaust tailpipe different, the absence of the radiator side covers, fork and levers are not adjustable and the FZ1 brake discs with a diameter of seemingly minor, compared to 320 mm . Although not visible in the photos, we know that the newcomer will be available in a version with ABS. The FZ8 has been enriched with a fairing below the discharges, which was not present on the FZ1. The similarities are evident with the Mille, however, in the frame and swingarm, which seem to be identical. The FZ8 is a bike with appointments easier than the older sister of 1,000 cc: simplification has been made to reduce the price and be able to create a competitor of the Kawasaki Z750. As known, the engine has a cubic volume of 800 cc. Being derived from a thousand, a reduction in tree volume of 200 cc to give rise to the propeller of the FZ8 seems to have been obtained by decreasing the bore: to introduce a shirt in the cylinder design would certainly cost less than shortening the race, which would require a redesign crankshaft and imbiellaggio. Compared to measures bore x stroke equal to 77 mm x 53.6 mm engine of the FZ1, estimating that a reduction in volume from 1,000 cc to 800 cc and a fifth fixed and taking the race to 53.6 mm, would decrease the bore to 68.9 mm. That of the FZ8 will, therefore, an engine Superquadrics. If the characteristics of the combustion chamber do not vary in substance if the piston crown and cylinder head to maintain the same profile although with a reduced circumference, should not change too much the compression ratio, which is expected to remain around the current 11 , 5:1 in the FZ1. In any case, the decrease in the bore, rather than race, in addition to lower costs would also have another benefit: Reduces the displacement losing the power, without sacrificing an excessive torque. Indication, compared to 150 hp declared for the FZ1, the maximum power of the FZ8 should be 120 hp.
