In 2013, Winston Yeh entered the World Championship of Custom Bike Building, traveling all the way to Germany from Taiwan in order to do so. He was rewarded with the win in the Modified Harley class. In 2014, he once again made the trip from Taiwan to Germany, this time to compete in the Freestyle class with his Dyna based build Graphite Speedster
HAVING won the Modified Harley class at the 2013 World Championship of Custom Bike Building, Winston Yeh returned in 2014 not to defend his title but to take on the Freestyle class. Due to the restrictions placed on custom bike builders in his home country of Taiwan, Yeh’s bike – Graphite Speedster – might at first look a little simple to be entered in Freestyle, but a closer look reveals just how much work has gone into radically changing a Dyna.
In Taiwan, while it is possible to modify motorcycles, there are many issues to overcome, as Yeh explains: “My country has very strict regulations for custom motorcycles, they compare the modified bike to a picture of the stock bike. This means I can’t radically change the frame or put long forks on a bike, otherwise it would be impossible for the customer to change back if needed to pass the government inspection.”
The stock front end has been dispatched, to be replaced by a one-off Springer, which features machined billet aluminum rear legs combined with tubular front legs with stainless steel highlights. The twin shocks at the top of the forks were originally meant for use on a mountain bike, but pairing them together here, Winston has made them strong enough for use on a motorbike.
With the bike now a roller, Winston turned his attention to the engine. The original Dyna motor was stripped down and then rebuilt with S&S Cycle front heads being used on both cylinders. However, before fitting the heads the fins on them were turned down to give them a more rounded look when compared to stock heads. The top end work was completed with Rough Crafts own finned rocker box covers. A custom 2-into1 exhaust was then made up in stainless steel and fitted along with a pair of FCR carbs, one for each head. The engine was then finished with custom pushrod collars from regular Rough Crafts collaborators 2 Abnormal Sides, who also designed and created the tank and head badges on the bike.
The gas tank, on which the badges sit, is a two-piece design that straddles the aluminum backbone. The right side houses the gas, and the left side carries the Ultrabatt batteries and electrics and is a quick detach design to allow easy access.
The only other bodywork on Graphite Speedster is the one-off minimal rear fender mounted directly to the swingarm. This, the tank and frame were then all shipped to Air Runner Custom Paint for finishing before re-assembly began, which included the use of Rough Crafts’ mid-mounted foot controls, lights, gas cap and grips.
