I see number 25 in the Ilkley Trial entry list is Tiff Needell and Tom Ford on a Ural in Class D. So it looks like something coming up on Fifth Gear! Lots of TBA's about the bike but I would have though its likely to be a bit heavy.
Looking at their website http://www.ural-motorcycles.com/index.php?products I see they do Sidecar Drive models.
They are running at the back of the bikes so I guess early car numbers like Stuart and Dudley should get top see them perform. Here is the Ilkley entry list http://www.ilkleymotorclub.org.uk/Classic/entries.htm
btw watch out for trialling in Practical Classics as their team were out in force on the Bovey the other week.
