As you've probably found out already, the CB175 is a cracking little bike, loves to be revved to the red line, actually seems to thrive on it
, capable of 80+mph even two up, and handles really well. In fact I'd go as far as to say that in town traffic they can make a 750 look rather silly. The only word of caution I have is change the oil regularly, no more than 1000 miles between changes, 500 miles is better, they don't hold a lot so it soon gets dirty. Enjoy riding it, and if you set the front brake up properly it should be almost as good as a cb200 front disc brake.
