VIDEO: Mackenzie fires up his GP500 Yamaha

Visordown's wee Scot blows the dust off his GP bike at the NEC Show

160bhp - 115kg - now that's a proper racebike

TWO STROKE fans sit back and enjoy this short clip of Visordown's Niall Mackenzie firing up his Yamaha France YZR500 Grand Prix machine.

The bike was ridden by Niall in GP500s in the early 1990s but is now in retirement as a show piece at the wee Scot's lair.

No chance a of a quick go, eh Niall?
