FORM450 got hold of this Junior Powerbike race footage from a Thundersport GB event at Premby that took place this past May. Here you can see Steve Tomes (#16) on the white RLR built WR450 Supersingle and Mike Edwards (#11) on the yellow/blue  Mark Hanna built RMZ450 Supersingle. Unfortunately the race is stopped when the red flag is pulled out due to a accident but that’s ok cause here at FORM450 we love anything 450 Supersingle we get our hands on, especially race coverage.
