I had a '78 DT 400, Just sold it last summer, I loved that bike, a great little rider, the 400cc 2 stroke delivers really nice power, great for buzzing around town or hitting the trails. Not really a great bike for all out motocross, nor a very good bike for serious freeway travel, a bit light and underpowered for the interstate, but great in town. Honestly wish I still had mine.
Here is a video of my '78 DT 400
My brothers would barley and I do mean barley hit 65.
Then something must have been wrong, IMO. That bike should be good for another 10-15 mph w/stock gearing - not that you'd want to run at 75 mph for any length of time. Did he have a big sprocket on the back end?
The bike in the pic is sweet. Wish it was available in my neighborhood.
Not sure when he had got it some one stripped alot of parts off it to make it a mx bike.
well that tells something , im betting that they put a tall tail on it . my dt 250 would do 75+ wide out .
the only big bike i had that was real slow for its size was my honda cb 550 k . it was a slug 55mph maxed out red line 5th gear . my yahama 100 could out run the thing . never could figure out why it was so slow
