Anyone know the speedometer/tachometer ratio on the 450's? Any other relavant information on the speedometer or tachometer could be placed here as well. For future newbie (me) use...?

Has anyone used any aftermarket speedometers or tachometers on a 450? Mechanical or Electronic? Pics?

I'm thinking most aftermarket items would fit based on the fact that the CB500T speedometer drive "should" be the same as the 450? If not then the cable would be different, seeing on how the CB500T uses the larger 500/550/?750? guages, right???

Steve has posted on this many times.
Most Jap bikes of this era have the same speedo ratios.
As long as the wheel diameter is the same, almost any speedo should work ok.
Same with tachs - I've personally interchanged both on many different Honda models of the 70's, and they worked fine.
Right now I have 360's on a 450, and I've used them from 500 4's, 350's, etc.

I did a search on it here, and did'nt find anything. Hence posting my question. Steve may have had it on another forum?

Anyway, thanks for the confirmation!!

Maybe you're right, Gerry.
Probably lost in the ether of the old Twins site......
