    Can I fit much later silencers?

    250K0.

    Does anyone know, with a little modification expected, if much later silencers will fit a 68?

    Even as late as Dream. Or Super Dream etc.

    I’m finding it extremely difficult to check or source silencers; obviously….

    I’m happy to take the gamble of buying a Super Dream silencer to test if there is a possibility it can be made to fit.

    Please be more specific as "Dream" or "Super Dream" means little without a CB/CL/SL/CA/CM designation, engine cc, and K model or year on our side of "the pond"......

    Sorry, good point as there was a Dream in the 60s!

    I was referring to the CB250N, so as late as 78-86.

    I know a lot of people don’t mind, but my K0 is very loud; don’t tell ancientdad….

    I just want to find something quieter. I’ve had a K4 years ago and I’d be more than happy with those silencers.

    I'm happy to forgo a little non standard to reduce the decibels. I’ve had a lot of bikes; too many and nothing comes close to the volume; maybe an old British bike I had…

    I’d be happy buying the CB250N silencers to try, but would need to get down pipes. If I cut mine and the silencers were bad, or didn’t fit…..!!!

    Since your CB250K0 is essentially a smaller displacement engine in a CB350K0 frame why not go with CB350 pipes and mufflers?

    Davidsilverspares.com should still have some decent quality reproduction mufflers that will fit your CB250K0;I'm referring to the CB350K4 model mufflers which I saw on their site a few months back.
    I have worked with CB350K3-K4 bikes and the model HM344 stock mufflers also has letter stampings in their cases which say CB250/350.

    Thanks both. I know they are the same, David Silver are out of stock, I have had them on back order with them since I got the bike!!!

    No one else in UK seems to list any K ones. Classic Bike sell some, but I’ve heard they are loud.

    I think that the pattern pipes sold by DS et al are / were made by the Brituro company, located in Birmingham.

    HONDA CB250 – Brituro

    Might be worth giving them a ring ?

    Ashimoto actually got them to make him a pair to his specification - unchromed, so that he could tidy the seam welds before getting them chromed.

    Thanks for that Richard, might be worth a contact.
    I know there is one in the UK whose pipes are louder; not what I want.
