As the name suggests, “Proto Slug” by Frenchman Fred Duban from Dub Performance is a very radical prototype street bike. A very sohisticated machine that required 1 1/2 years of very hard work to conqueer the imagination of all bikers, of all custom builders and this week in Sturgis the favorable votes of the judges of the AMD World Championship Of Bike Building (August 2-5 on Lazelle Street at Champions Park).
And yes, I am extremely objective and I bet that this ultra custom machine is going to reach its main objective: by pushing the limits of what can be done in terms of design and technology, to emulate other custom builders around the world to surpass themselves and do even better in 2010. 18 months of sweat, blood, trials and errors later with crew and friends as daily support (it includes weekends), and after spending 250,000 Euros (about $350,000) of his own money, Fred Duban just completed his dream performance street bike. And if you are not in Sturgis to dissect all the tricks included in this prototype I give you the main basic ingredients of this custom building recipe.
“Proto Slug” started as a with a 32-degree neck street frame heavely modified by Dub Performance to accept a 100% hand made carbon fiber body, an aluminum gas tank and a plethora of fabricated or custom modified parts. Motor is 131” 2200 cc from Merch fitted with a Mikuni HSR 45 and coupled to a 6-speed Baker transmission and Primo drive. Öhlins provided the front end before it was also modified, equipped with an 18” front wheel stopped by a Beringer performance brake and dressed with an Avon 120/70. In the rear, there is a massive 18” wheel also dressed in Avon 300/35. Controls, grips, bars come from Italian Rizoma. Most of the other performance parts were made at the shop. The tricks? Will explain to you when Fred let me use it. To follow…Dub Performance.
