Speedo Tacho Ratios
This is a guide to Tachometer and Speedo ratios for some of the most popular modified motorcycles.
We try to keep this list up to date and correct so if you want us to add a bike or you see an error please let us know and we will amend it.
If you are unsure about your tachometer ratio don’t forget we sell the electronic tacho’s as well.
(edit: 2240:60 is 2240 revs at 60 mph which is the common speed for most stock standard Japanese bikes. Different tyres and rim diameters will affect this)
