For anyone with the BT sport package, they are running classic 500cc moto gp races each night on BT sport 2. I have the channel by default as I was already a virgin tv xl customer. The racing is much more exciting than it is these days sad to say. I was never into the bike racing in the 90's so its all new to me and I love it!!
1992 Dutch GP, Monday 4th November several repeats during the day. BTsport2. Not sure which channel number it is srad, sorry.
They're on BT Sport 2 at the moment and will be on btsport.com soon as well. There'll be a new batch of races coming soon. Keep an eye out for some good stuff at the beginning of next week.
