The CB 350 F is a very sweet bike. Goodlooking, easy handling and the real fun starts when you give it rpm's of 4-5000 and up. They are build to run on high rpm's and can really give you a lot of fun on the winding roads, or just down the road for a coke or an ice cream. I love mine and it will stay in my collection.
Yes, it was Soichiro Honda's favourite bike. Maybe because he was not that tall

I am 183 cm and no problem riding it.
Next level up is my CB 550 K0 which is a great bike, too. Recommended, indeed. I use that one a lot, as it handles so well and better balance than my CB 750 K4, which is my touring bike and have the better sitting position.
