Lumley Engineering - Dave Langley's Sprint Yamaha Fazer Outfit

Dave Langley loves bikes, speed and sprint racing. He is not the sort of character to let being a long term wheelchair user stand in his way. The idea is simple; bolt a vestigial sidecar to the side of his Yamaha Fazer, so that he can roll his chair into position then switch to the bike seat to take part in sprints and drag races.

As this was an experiment, nothing could be welded to the bike in case it needed to be brought back to standard quickly. One big change was to fit our bespoke leading link forks to the bike to give Dave better straight line stability and more control. We included a variable mount for the bottom of the spring units to give a degree of adjustment and away he went. The result: he loved the way the outfit handled. His next project is to add nitrous oxide injection for next season.
