Lincoln County Customs's Troy Johnson (who happens to be the Factory Yamaha hillcimb race director) was in charge of the build, and he replaced the stock clutch with the Rekluse Z-Start Pro auto clutch and Rekluse clutch cover.
Next, Troy replaced the factory water pump impeller and cover with the Boyesen Supercooler, which have taller impeller blades and increase water flow and cooling efficiency.
Troy also installed a set of Windham-bend Pro Taper bars, Renthal kevlar grips and hand warmers.
Toyskinz designed and supplied the wrap, which should stand out in a sea of white snow and dark trees for photos. We wrapped the Mountain Horse tunnel sides and top to protect the powder coat finish. The Toyskinz wraps are very durable and will keep the WR450F looking new all season despite our inability to stay out of trees.
