Does a K3/K4 seat fit an F1/F2 CB550
« on: October 19, 2018, 11:49:25 AM »
Hi...I have a 1977 C550 F1 (made in 76). I have found this on eBay:

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F391573891719

Would this fit my bike ok? Everything else is standard.

Thanks!

The hinge and the pin should line up, but it will interfere with the grab rail I think.

Will not fit right and the same seat cheaper price >>> https://www.davidsilverspares.co.uk/CB550K3/part_28994/

You may find a member that has a K3 with a F seat that may want to swap seats  ;)

Moreover it will look awful. The original is sportier than the one for the K3/4 which model was marketed as tourbike.

Thanks for the advise guys. I did look at David Silver, but they were out of stock a while ago. Thanks!

Not sure if DSS has upgraded the seat pans to metal. Had a plastic one some years ago that used to squeak all the time  ;)

Hi 3scs....I would love to swap, but unfortunately mine is a non standard lowered seat that you probably wouldn't be interested in. See attached pic.

If not, would you be willing to sell your seat and put the money towards another?

When I bought a CB550K3 as a commuter it came with a sportier seat



But as Mrs.Yoshi is a bit of a short@rse I fitted the seat to her CB550F2



And fitted the F2 seat to the K3
