Honda CR480 Twinshock. Motocross, VMX. 1980 CR250 Red Rocket

Honda CR480 Twinshock Machine

Arguably. the finest open class twinshock motoX machine available in the world today.

Built by Phil Denton Engineering to full factory spec. One of the Team USA bikes for the 2012 Vets MXDN.

This machine has been used only 3 times – it was raced by Chuck Sun at Farleigh Castle 2012. it was subsequently tested by Ed Bradley for the November 2012 Issue of DBR and finally was used by Team South Africa in the 2013 Vets MXDN.

The spec of this bike is as close to a full factory machine as it is possible to get. All used parts were fully re-furbished to as new condition during the build and a vast array of very special new parts were also fitted. including a new. British made. 5 speed gearbox. KLP alloy swing arm. Holly Equipe fuel tank and ‘top of the range' Works Performance ‘Racer' piggy back shocks.

There are lots more pictures showing the build up of this bike on our website (www.phildentonengineering. com) in the gallery and news sections.
