My 1960 C72 now has a bigger brother in the form of this 1960 C77. Engine and frame numbers are within one digit of each other and both begin with an 'A'. The motor has 10mm spark plugs and the rear breather tower.

The bike was imported from California some years ago and has sat in a garage since. I followed up a message from this forum and picked it up at the weekend.
I am interested in Honda history and this one was one of the first C77s imported to the US in 1960. The handlebars have unusual lever perches (no mirror mount) and other controls which came from the CE71 Dream Sport (model code 257). Rear shocks have metal covers and I have a replacement lens for the tiny rear light

The bike came with some good NOS and used parts so the restoration shouldn't be too painful. I will have to graft on a replacement rear end but that's all part of the fun isn't it?

Currently the motor is seized and I am missing the carb, which I am told is different from later C77s and CA77s.
I might get one of these finished one day!!
