Take a 1975 [[Yamaha_MX400| MX400]], paint it Yellow and add the spedo air forks and you end up with the 1976 YZ400C (I only saw 1, I swear it felt like an MX400). | Take a 1975 [[Yamaha_MX400| MX400]], paint it Yellow and add the spedo air forks and you end up with the 1976 YZ400C (I only saw 1, I swear it felt like an MX400). | ||

Expanding on a good thing, the 1978 YZ400 became stable with the box section aluminum swing arm and longer travel (at both ends). The bike was a bit heavy (tipping the scales around 240 lbs.) but long gone was the cracks in the frames, common with the previous (non-Monocoque) designs. The rake was also a bit long which made the 1977-1978 YZ400s better at cross-country than in motocross. | Expanding on a good thing, the 1978 YZ400 became stable with the box section aluminum swing arm and longer travel (at both ends).
