Dam Tech Twin American 13c Pennsylvania 2011 — Specifications

In 2011, DAM Motorcycles took great pleasure in trampling on American custom conventions. Their Twin American 13c Pennsylvania is not just a two-liter V2; it exhibits mechanical architecture worthy of a racing prototype, grafted onto a low-rider silhouette. The result is a declaration of war against Milwaukee’s mass-produced offerings, a motorcycle that seems to have come straight from the workshop of a mechanical artist.

The heart of the beast is this four-stroke V2 of 2081 cc, developing 140 horsepower. Manufacturer's data are sparse in details, but this power figure, coupled with a six-speed belt final drive, suggests a very particular torque curve. It’s not the low-frequency rumble of a large classic twin; it’s a mechanism that must breathe, push, and probably sing with a higher-pitched and more nervous voice than one expects in this category.

The chassis reveals the machine's true ambition. The frame is signed DAM Motorcycles and Apex, the fork comes from the expertise of Penske Racing, and the single-sided swingarm is a house creation. The brakes, front and rear, are single discs gripped by four-piston Brembo radial calipers. This selection of high-end equipment, usually reserved for pure sportbikes or super-nakeds, betrays a will for performance at all costs. The tire setup, with its monumental 240/40-18 rear tire mounted on an 18-inch rim and the slender front tire in 80/90-21, confirms this search for a radical style and an engaged handling.

This Dam Tech Twin American is the antithesis of the cruiser designed for mass production. Every element, from the DAM/Apex frame to the specific swingarm, shouts exclusivity and pushed personalization. It is not aimed at the touring rider seeking transcontinental comfort, but at the demanding collector, the rider who considers a motorcycle as a mechanical work of art, a kinetic sculpture where every bolt has been chosen for its function and its aesthetics. It is a unique, fierce, and definitively out-of-the-ordinary proposition.
