Pete Ludlow's 1975 CB400/4
By Ross Sharp - 10 Oct 17
Peter Ludlow recently became a member to the Bike Shed and here's his lovingly restomodded Honda CB400/4 "I’m a qualified Mechanical Engineer working in IT. I’ve been rebuilding bikes on and off since the late 70’s as a hobby." "I bought my first 400/4 in 1978. Over the years I owned it, I converted it to what was at the time the fashionably racy look, although I don’t remember ever calling it a ‘Cafe Racer’. It ended up with flat bars, bikini fairing, two-four seat, yoshi 460 big bore kit + race cam, mag wheels, fibre glass mudguards, bell mouths and a piper exhaust." "In October 2016 – I decided to get back into classic motorcycles; I found a Blue 1975 US imported ‘barn find’ 400/4 on eBay. The idea was to build myself a Cafe Racer. The donor bike was in pretty poor condition. However, I did find a few good signs – the rubbers, engine internals, disk wear, and overall look of the bike I think confirmed that the 7320 miles shown on the clock was genuine."
