“Seven” By LC Fabrications

LC Fabrications Show Off Their Buell, Ducati, And Triumph Hybrid

Updated August 9, 2018

Now this is what I call the definition of custom building. Who would dream of mating a Buell with a Ducati and fusing it with a Triumph transmission? Jeremy Cupp from LC Fabrications, that’s who.

It’s appropriately called “Seven” – as it’s the seventh proper motorcycle to roll out of the LC Fabrications garage and it’s a real mean machine that takes inspiration from the Harley Davidson CAC Speedway machines from the 1930s mixed with a variety of European parts in a way that may not have ever been seen before – as custom motorcycles go, this is an absolute masterpiece.

Jeremy Cupp, the man in charge of LC Fabrications has always had a passion for motorcycles, engineering and machinery and has spent most of his life tinkering with Japanese bikes, but always dreamed of playing around with a Harley. As soon it was a financial possibility, he built up some Evo 883 machines and eventually went into business under the name LC Fabrications, based out of Grottoes, Virginia.

The inspiration behind this build was all about building a race machine that was reminiscent of an vintage racer, whilst still respecting the craftsmanship and skill of the old days. It’s a fusion of past and present, and better still, it’s a fusion of more than a few classic machines.

Cupp had seen and admired Chris Barbers work from a few years back, the “DesmoHarley”, and wanted a slice of the action for himself – rather than putting Ducati 900SS Desmo heads onto a Harley engine, Cupp went a step further and built an even more outlandish Frankenstein engine. Starting with a 2001 500cc Buell Blast engine, Cupp swapped in some Ducati 750 SS cylinder heads and mated it together with a pre-1959 Triumph transmission, which was modified to work with a hydraulic clutch slave from a present day Triumph unit. According to Jeremy: “The entire cam-chest was modified to use a series of idler gears to drive the lower belt pulley. The Ducati 750 ss cylinder head had also been heavily modified to take its place on top of the factory Buell cylinder.” Which is serious business…

The engine now rests in a hard tail frame with a 32-degree neck rake. Up front, it’s given some bounce with a custom made ‘Springer’, with a rear leg modified from a 32mm Showa unit that had had the springs removed, acting as dampeners only. It’s a strange piece and Jeremy calls it the “Hydro Springer” with hopes to make up a small production batch for sale in the near future.

Underneath, “Seven” rolls on a new set of wheels, with a 23” rim at the front and a 21” at the back. The rear wheel also houses a perimeter rotor that’s powered by two Jaybrake calipers with separate master cylinders, providing all of the stopping power from the foot brake and the traditional hand brake, leaving the front free of all braking responsibility. Get your head around that, eh?

The part of the build that really draws the eye, is the amazingly crafted aluminum sheet metal work. The gorgeous gas tank has been massaged into shape with precision and finished with an elegantly polished surface. Jeremy crafted all of the sheet metal work from scratch and completed it all by himself. Jeremy’s talents don’t end their either, he also bought himself a sewing machine and taught himself how to upholster properly; as you can see here on the saddle of the “Seven.”

The “Seven” is a remarkable motorcycle and the final result of two years’ worth of hard labor. If you want to see it in the flesh, get on your bike and head up to Sturgis, where it will be sitting in pride of place for all the world to see.

I’ve done a bit of work here and there in the industry – I’ve even ridden a few bikes for actual money but what it comes down to is this: I ride bikes, build bikes and occasionally crash ‘em too. I like what I like but that certainly doesn’t make my opinion any more valid than yours…
