Model Name:CYGNUS X SR


Model Year:2006

It was a motorcycle based on the CYGNUS X. It adopted a rear shock absorber with a 3-stage spring initial adjustment feature and an exclusive color graphic to emphasize its sporty impression. Its basic components, such as its air-cooled OHC single cylinder engine with 4-valve heads or plated cylinders, the compression rod type engine mount that absorbs uncomfortable pitch motion, or its front and rear 12-inch tires have not been changed. The MY2006 version became even more sportier by adopting red front brake calipers.
