Yep, that's me and Vic at a little private track near his old shop back in the late 70s. We took the first 440 we got in house and tricked it out for an article Vic was writing for Modern Cycle. Look closely and you can see the Mikuni on it.
This was the photo shoot day. Vic did all the riding on the new 440 that day but I got to burn laps on a tricked out coffin tank Maico 400 so I wasn't disappointed.
That 440 was the best bike I had ever ridden at the time. Might still be :)
