Finally I’m posting some photos of my modified front end. I’m not even half way done, but it’s looking sweeter everyday, and the performance is much improved. The speedo is the proper 2240:60 ratio and the tach is 20:3 ratio, sometimes referred to as 1:7. The bar clamps are made by Carpy, and the radial master cylinder is off a 2008 Honda CBR600RR.
These are some gorgeous little gauges and the look even better next to each other.
Fresh stainless steel bolts on everything.
The reservoir sits perfectly level now. I’m so happy.

I have almsot the same bike as yours, mine is a 1976 Honda CB550F. I am looking at the same speedo and tach set up you used, which look awesome by the way!
How do you know what is the correct speedo and tach ratio to use? I see you mentioned 2240:60 for the speedo and 1:7 for the tach.
MikesXS is a good source for the mini speedo but they said all of their speedos are a 1:2 ratio. Will that ratio also work for the CB550?
Thanks for your reply.
Hey Glenn
I did all my research on the SOHC Forums. I can guarantee that 1:7 is the correct ratio for the tach. You don’t want to use any other ratio for a 550. I got my tach from Cycle ReCycle who were the only dealer that even listed a 1:7 tach. A 1:2 tach will get you in the ball park but it won’t be accurate. Thanks for posting a comment, hope you enjoy the site.
I checked CRC2′s website but didn’t see a black faced speedo with indicators. How did you pull that one off?
Thanks.
Pete
Who did you purchase your Speedo from. I cannot find a 2240:60 with black face anywhere for my CB550F
I found it right on the CRC2 site.
