I saw the Lazareth Wazuma V8F on the Top Gear site last week and it stuck in my mind. Here's my Lego version of the idea. It's not meant to be a replica of it, just a feel for the machine that will bring certain death for those that ride it. I couldn't build a reasonable handlebar for it, so resorted to the steering wheel.
About this creation
Small Capacity V8 hooked up to a sequential shift manual gearbox. Open exhausts and a pillion seat that will result in your arse cheeks and thighs getting shredded by the rear tyres.
