This was bought as a part project, a 1973 Honda CB125S1 and before any old guys in flat caps start shouting sacrilege there is a pic of how we got it.
Where do we start with this write up apart from the obvious questions... "I bet that doesn't handle!".... haha no it’s not the best handling bike in the world. The trail is so far out making the bike brilliant in a straight line but a handful around tight bends. "Bet you can't ride that far!"....Well you could if you really wanted too but this bike was never made to go touring on so no it wouldn't be my first choice for riding around Europe. "Does it pull to one side being a single front end?"... It’s actually quite balanced but this isn't the first single sided front end made so the science is out there to make things right with a bit of research.
About the bike now.... This bike was hand built and machined by hand on an old Bridgeport miller and a Machinemart lathe. While watching the great bake off one night with the little CB sitting in the living room talk turned to the bike about just what we could do to it. Many ideas was put forward and in the end a hardtail chop with single sided front and back ends was decided upon but with a 60's flare. The main cradle was left standard but a new hardtail rear was fabricated and welded on. This was done after the wheels were machined though so we knew what offset the frame needed. The wheels are two rear wheels from a Yamaha YZF125 that's had the cush drive machined down on both wheels and new bearing cups machined into the wheels. With the front wheel done the girder could then be designed and built from a solid piece of aluminium. The bends weren't machined in but rather the aluminium was placed into a 16 ton press and the two bends formed. This was then transferred to the miller where it was checked for straightness. Once this was ok the arm was machined to suite the hub for the wheel and also the suspension set up. I'll be the first to admit the handling isn't brilliant. By keeping the standard headstock but racking the front end out its brilliant in straight lines but corners are...well corners aren't its most favourite of things haha. This was never built to go touring on though so that was never going to be an issue. The tank is from a royal Enfield that was chopped in half and welded on the main cradle and fitted with a flush filler cap. The rear mudguard was hand beaten then put onto an English wheel to smooth the lumps n bumps out. The seat base was actually welded on the frame making covering it a challenge. The paint and powdercoat was by APC they did a cracking job if i do say so myself . There's many many more details so check out the pics and if you have any questions please just ask
