Honda CB160/175 Close Ratio Conversion Gearbox

<< back to products

Whilst not a true close ratio gearset, it does improve spacing of the ratios particularly in the higher gears.  To keep cost to a reasonable level the ratio changes have been made to the least expensive gears.  Only the gears underlined below are supplied by Nova and should be assembled using all the other retained standard Honda gears, shafts, circlips, bushes, etc.
