I have written a lot about modern bikes recently, so let’s go back to the 70’s.

The Honda CB175 was my “step up” from the CB125S that I learned to ride on (and passed my test on (in 1974…). As a twin with twin carbs, it was the sporty side of Honda that was a reflection of the cooking CD175 commuter.

The CB175 had a 360° engine, meaning that the two pistons went up and down together and had a very smooth firing order. Given a decent exhaust, the engine “roared”! [The later CB250 had a 180° twin with the pistons in opposition. This gave better primary balance but an offset firing sequence which gave those models their off-beat exhaust sound.]

This one is a K6 and has been in the family for the last 5 years. I’ve just sold it to a guy from the Honda Owners Club who wants to do a proper resto on it.
