CB1 has a 17" wheel. AGB-1Nice looking gauges and I imagine easy to fit. The wiring should not be mush of a problem to modify. One question though - what front wheel size is it made for - is it the same as the CX?. If it is then no worries - if not then the gauges would be highly inaccurate and would take some explaining to the POLICE if caught speeding " honest officer my speedo said I was only doing 55 " when done for travelling at 70 plus LOL
