Here are some videos of the 1985 250cc season.
Finally some videos of the ND5 
!!!
Spencer was actually a works bike called the NSR250W, but its stil an ND5 
It was carachterized by having Magnesium cases, derived from the 500.
The rest of the drivers, had the real ND5; and if you understand french, you can hear in the first video, that one of the top runners in that race, was racing an “over the counter” privateer bike… Just like mine 
Enjoy!
