1971 Honda CB450 K4

1971 Honda CB450 K4 restored to as-new
When I first saw this bike, I thought it was new—Honda jumping on the SR400 bandwagon and manufacturing an oldie for the home market. But it isn’t. It’s an amazingly meticulous restoration by reader Bill Lane, who bought a rusted out CB for a couple of hundred bucks. “Some nice parts came my way, and I figured there were plenty of restored 450s around already,” says Bill, “so something different was called for.” To clean and de-rust the ancient components, Bill got through an awful lot of that dairy industry staple, milk stone remover. Then he powdercoated the frame and totally dissembled the drivetrain, with every part cleaned, painted or replaced. A Barnett competition clutch went in, along with a new wiring harness and Yamaha XS650 coils. The shocks are from a 1981 CB750 and the mufflers are Emgo Roadhawks. The wheels and forks are from a 1979 CB400—which bolt straight on if you can lay your hands on a CB360 stem and clamps. Bill took care of the paint himself, finishing with Duplicolor Ultra Silver and a two-part clear-coat. He’s thoughtfully posted a full write-up of the restoration online, complete with excellent pictures. If you’re looking for inspiration to get started on that wreck at the back of your garage, you’ll find it here.

  • What a fantastic restoration job he did. It looks pristine and perfect! Looks like the little brother the CB500 Water Buffalo I had when I lived in South Africa. But that old 500 was nowhere near as nice looking as this 450. Excellent work!

    fantastic craftsmanship in the restauration. Too bad,because the bike itself is a bit too UJM to my taste.

  • i’m seriously jealous! such a beautiful bike!

  • Josh

    Perfect restore of a boring bike. throw some clubmans on at least and yank those awful turn signals.

  • Josh,

    Then he would have a boring wanna-be-poser cafe bike like every other hack restore. This bike is a perfect example of a clean restomod. A bike doesn’t have to have a set of clubmans to be cool.

    The builder is a true craftsman, and an asset to the 450 community as whole. Well built ride Mr. Lane!

  • Josh

    No question to the level of perfection that went into this. Props.

    But i guess i see things like turn signals and clubman shaped bars still quite an un-modded bike. Still even with those things it would be a boring, but perfect restomod of a 1970 CB. Id kill to see a nicer bike restored with this level of skill and dedication like an AJS single or and old Norton Commando.

    Beautiful bike/ excellent job. Wish it were mine. The bike is modified. Someone correct me if I’m wrong but I don’t believe the bike was stock with black engine, comstar wheels, stubby winker stems, the paint color, a solid tank strip. Not sure if those are stock pipes but they if not they look close. Anyway…none of that matters, it’s a beautiful bike.

  • It’s the subtle things that make it a truly nice bike.. If it was like Josh would have, it’d be just another redone old bike, IMHO.

    Good job, very nice.

    For RicH2 –

    Click on the link that says “full write-up” for all the lurid details and a ton of hi-res photos……

    To me those 1970’s Hondas are just beautiful. Great job.

  • Very nicely done! And thanks for posting the link with details and photos on the restoration/update! I got some ideas for my own CL360 I am working on!

  • I have never been a great fan of comstar wheels, but now that I can see how nicely they update an older machine, I’m rethinking my aversion to them. They really are the keystone to this whole update, and the whole project just looks smashing!

  • TED

    I think it looks fabulous.

  • Steve

    Those wheel are late 70’s model. The 71 had wire spokes. Other than that, a nice restoration…

  • Ken

    Add a 1 in Black Stripe to the front fender, with gold pin stripe on each side of the black .

  • Awesome Job! I’m riding a stock 81 cb400t and all the great work you did is inspiring me to put a few custom touches on myself. Specifically the painted engine and different springs in the back. You’ve done a great job and I hope ur very proud.

    If you set out to do a 100% original restoration there is always someone who will point out that the pinstriping should be 2.5mm, not 3mm: or it is the wrong shade of pink or some such.
    At the other extreme one can build the most radical ever chooper/cafe/whatever, until someone ups the ante. But it will probably not be usable…
    In between these, in the real world, it should first and foremost please the owner. And if that was me I’d be proud of it.
    Has a “period” look about it yet so well done that – as said by others – could be mistaken for a new machine. And eminently usable, would be at home commuting, touring, at a bike show, on a sunday ride.
    Well done that man!
