1976 Honda Cb400 Four. In usable condition. This is an original bike . The rebuild took just over a year and no expense was spared on quality or attention to detail. The bike has been on the road since August 2019 now and now completed over 500 miles. Restoration work includes:

Frame blasted, inspected and powder coated. Special care was taken to retain the frame number. Forks hard re-chrome and ground back by specialist, then rebuilt with new seals. Engine completely overhauled, including vapour blast by a restoration specialist, then inspected by an engineering specialist where it was found to be within tolerances of the original size pistons so received a light hone. All engine components were measured and those within acceptable tolerances used and new old stock parts sourced before reassembly.

New parts include:


One of the side panels (saved the original other side)

Rear shocks

Tyres & tubes

Steering security lock

Brake pads, master and slave cylinder, all brake pipes

Chrome mudguards front and rear

Chain & both sprockets

Engine internals (pistons, rings, all main bearings, main bearing shells, primary HyVo chain and cam chain, cam chain tensioner repair kit, all seals and gaskets)

Battery, bulbs, fuses, horn, spark plugs and caps, points

Clutch and both throttle cables

Everything else has been meticulously restored while retaining the patina a 46 year old bike deserves. Other highlights include the headlight shell, clocks, regulator, wiring loom, horn and passing light button (which was 3d printed!)

If you know the 400/ 4 you'll be aware of the familiar faint cam chain rattle at idle speed. This one is no different! Also the earlier engines had shorter head bolts, later revised to cure a slight oil weep sometimes visible on the left side - again, this one does show small signs after high revs. The left frame rail has been previously repaired with an external sleeve. The repair was inspected after blasting and found to be very secure so it was left in, and the powder coat went on. The red tank has some light damage, small dent near the seat (you can't see it when the seat is in the usual position) and some scratches around. I may be being picky referring to these points but I'd hate for someone to arrive to see the 45ish year old motorcycle expecting to compare with something brand new!

Everything works on this bike as I believe it should. The switchgear is positive and tactile, the ignition barrel is positive. There are 2 keys (one new and one original with the same pattern), the keys fit the ignition and the seat lock as intended. The steering lock has been replaced as the bike came to me without the key - so that's restored and working well. It starts, stops, handles and behaves exactly as the 400/ 4 should, and represents a good, honest, reliable and fun bike.
