Here are some photos of my 1965 Honda CB77 305 Superhawk. I have owned this bike for 50 years now. It has been in this basic configuration since 1972 when I fabricated the disk brakes, Fairing, tank and seat from scratch. These pictures were taken at Hallett Raceway in Oklahoma in the last couple of years. I restored the bike about 12 years ago and have been doing one or two track days a year with it, up until last year when I retired it. I should also mention that I'm 71 years old. By the way, the guy passing me in the first photo, dropped it right after this picture was taken.

1965 Honda CB77 305 Superhawk Vintage Racer
Purchased new by owner
65,000 street miles
All modifications fabrication and paint performed by owner

My Vintage Racer is a 1965 Honda CB77 305 Superhawk, purchased new just after I got out of the Army. I started racing it in 1966, with some really ugly, homemade bodywork and 250cc sleeves and pistons in the engine, but it was hopelessly outclassed. So, after struggling unsuccessfully with it for a couple of seasons, I retired the Honda, put it back on the street and bought a Yamaha TD1-C, which I raced until 1972.

For the 1972 season, the AMA changed their rules to allow 350cc 4-strokes to compete with 250cc 2-strokes, so the Yamaha was sold and the 305 was converted back into a racer. Even though The Yamaha was fast and competitive, it didn’t handle or stop particularly well and was a lot harder to tune and keep running. The rule change gave me the motivation and my occupation, in the Aerospace industry, had given me a good set of skills in the disciplines I needed to build the bike I that really wanted.

I have performed all of the fabrication, modifications, assembly and paint work myself, with the exception of the cylinder boring and the porting of the cylinder head. It was raced off and on until 1983 and though while initially competitive, it got slower and slower relative to the competition and the water cooled two-strokes had become so much faster that I had to ride way over my head, to even try to keep up with them. After a crash in 1983, it was parked outside on a trailer in the backyard and I moved on to endurance racing. I finally got tired of mowing around it in about 1995 and decided that I would restore it. I didn’t realize it would take me nearly 9 years to complete the project, but the result has been more than worth the time and effort. With a few exceptions the bike is as it was put together in 1972, including the paint scheme, which copies the Honda works racers of the ‘60’s.

Here’s a list of the modifications I have made to it over the years.

Here are a couple of shots with the fairing off. The first one was taken about nine years ago, when I was experimenting with the brakes. I made my own wave rotors. The second naked shot was at a car show about two years ago. I've also included my current sportbike rides, a 2012 KTM RC8, a 2002 Honda RC51 and a 2011 Honda CBR1000RR Repsol Edition. Not a bad stable for an old guy.

Here is also a link to some You Tube videos of the old bike in action.

No, At present I am an Engineer with Airbus Americas Engineering in Wichita, Kansas. I started out as a Sheetmetal Assembler, worked my way into Tooling where I worked as a Pattern Maker, Jig Builder and Machinist/Tool & Diemaker. From there I moved on into Tool Design and NC Programming. I have been working as an Engineer since 1983. My previous occupations gave me the skills to build this bike.
