Capturing Motocross with Slow Shutter Speeds

Whats the slowest shutter speed you can shoot to achieve useable images?

I decided to find out at the local MX track. These photos were all shot on a Nikon D750 using a 25 year old Nikon 80-200mm F2.8 lens. The lens nor body has any form of stabilisation or vibration reduction. All these shots are hand held which means no monopods/tripods.

The useable images i came away with were taken using a shutter speed of between 1/25th sec to 1/50th sec at 200mm focal length. This is very slow for a 200mm lens of this age and not advisable if you want a great hit rate of sharp in focus images. I had never tried to shoot with a shutter speed this slow on this lens and so I was pleasantly surprised to find that many of the shots worked and had the effect i was aiming for. What I wont tell you is how many shots were complete rubbish and blurry/ out of focus ( Hint- It was A LOT ).

Motocross at Krusic's Ride Park- Gippsland

Spent an awesome weekend away at a friends holiday house at Golden Beach in Gippsland. Had such a great time away from the city with mates, talking smack, drinking and the best part is that Ride Park was just 5 mins from our house. Ive been wanting to  check out  Krusics Ride Park  for a few years now but the distance was just too far to make a day trip out of. 

I hadn't been on a MX track in 3 years (plus i'm also really bad at MX) but had a heap of fun. After my body couldn't take any more of a beating i parked up the bike and headed out to take some photos of the proper riders. 

Does anyone want to trade MX lessons for some photos? :P
