Last minute replacement, Brian Marr, fills a void in the Extreme Trials demonstration and shows off his riding skills to an appreciative audience... After torrential rain on set-up day at the Great Scottish Motorcycle Show, the opening on Saturday was dry, bright and inviting. Tim Britton was overseeing this morning's Extreme trials demo with Bon Accord motorcycle Club member Brian Marr who gallantly stepped in at the last minute when circumstances meant the original display demo team couldn't make it. Brian's freestyle exhibition will be going on throughout the day, though there will be a recognised session where Brian's skills will be explained. A very tiny trials course laid out with a massive log and couple of tractor tyres plus one or two traffic cones stands in for trials obstacles and allows Brian to demonstrate all of the skills a modern trials rider needs. Brian is riding Gas Gas, which is a lightweight Spanish two stroke, and very popular with the trials boys. At some point later in the day Classic Dirt Bike editor Tim Britton will be demonstrating the pre-65 version of trials riding.
