Sylvain and Florent Berneron’s PRAËM is a recent addition to the elite customs world. Although the company first appeared in 2014,the two are far from strangers to the design and engineering industries. Their knack for outstanding design, top-notch build quality, and superb execution have earned them an elite status despite only having built a few bikes.


Here is SP3 - Modified 2002 Honda RC51 that is stripped of its bodywork and lighting. New designs were drawn up that gave the Honda drastically different lines while still using the RC51’s solid stock geometry. After meticulously poring over the machine, the brothers concluded that there are some overheating issues resulting from the rear cylinder’s proximity to the tank – a fact a quick search on a RC51 forum confirms. The power-plant was broken down and rebuilt using titanium valves, a lightened crank, JE high-compression pistons, tuned cylinder heads, a Power Commander, a ram air intake, racing filters, and titanium headers with a stainless pipe. According to PRAËM, their RC51 now makes a cool 165hp and 92.2ft-lbs of torque.




The suspension is made up of Öhlins units in a custom blacked-out finish – an FGR300 up front and a TTX36 monoshock in back. The Honda’s front-end is made up of various one-off CNC-machined aluminum parts, and aside from the suspension-related hardware, all nuts and bolts used throughout the build are titanium. Next a pair of ROTOBOX carbon fiber wheels were selected that weigh in at just under 15lbs for the pair. These lightweight wheels were then wrapped in Pirelli Diablo Supercorsa SC2 super bike tires.


For the ambitious bodywork. First, a handcrafted aluminum 12-liter tank was created featuring large cut-outs specially designed to remedy the stock SP2’s rear-cylinder overheating issues. An aluminum belly-pan was added, along with various aluminum and brushed steel side-panels. The stock HRC-designed frame was slightly modified to accommodate the new bodywork, and a custom aluminum subframe was fabricated to accept the new tail-section. Other minor one-off knickknacks were fabricated such as the aluminum number-plate holder, antique brass engine spoiler, modified magnesium engine covers, and carbon fiber rear fender.
