The DG swingarm was a custom made arm for Erik Kehoe, another inch longer than a standard DG gold arm, a former DG employee from back in the day had it new in a box
and sold it to me for my build

Very nice, brings back memories. I had that bike when I was a kid. I did not have the swing arm but I did have a Factory Fox Shock and the fork caps.
Thanks for sharing

Very nice. I had a 1976 YZ80C when it first came out. It was like cheating.

Very cool bike! I am no Yamaha 80 expert, but curious if this is the stock frame and tank?. Also the forks? Got a build I need to do, this may just kick the starter enough!!!! Again, fabulous job to the builder!

Stock 1979 frame modded, hand formed skid plate, beefed up engine mounts, stock 1979F tank- repainted with Speed n Sport repop graphics( really nice stuff)
Stock forks hard chromed, ground back to a .020 oversize, heavy springs, DG caps

I removed over 15 lbs of steel, by removing many of the crummy steel stock parts

As an 11 year old, I had the D (‘77). Thumbing thru the DG catalog was better than a 70’s Playboy magazine. Yours is amazing!
