Frateschi Garage, based in Sao Paulo, presents an impressive creation called the RD Turbo—a striking tribute to Yamaha's legendary motorcycle, the RD 350. This unique build takes the iconic two-stroke engine of the RD 350 and infuses it with new life by upgrading it with a modern four-stroke R3 engine. To further enhance its performance, the bike also features an exhaust gas turbocharger.

Maintaining the original tubular steel frame from a Yamaha RD 350 LC YPVS, Frateschi Garage's mastermind, Renato Frateschi, skillfully transplanted a liquid-cooled, 321cc 180-degree twin-cylinder engine from Yamaha's R3 or MT-03 models. Recognizing the differences in power delivery between four-stroke and two-stroke engines, Frateschi decided to give the 321cc twin an extra boost to delight RD fans.

To maximize the café racer's capabilities, Frateschi incorporated a specially ordered turbocharger, optimizing the exhaust system, turbine, air box, and injection nozzles. Without the limitations of Euro 5 regulations, they had the freedom to fine-tune the bike according to their preferences. Through the turbocharging process, exhaust gasses spin the impeller, compressing the air entering the engine. This results in increased airflow, more boost, and ultimately, more power.

Not stopping at the engine, the suspension of the RD Turbo received significant upgrades, featuring an adjustable upside-down telescopic fork at the front and an aluminum swingarm sourced from a Triumph Daytona 675 at the rear. The braking system was also enhanced with the addition of radially adapted four-piston Brembo calipers.

To retain a classic aesthetic, the original wheels were replaced with 17-inch wire-spoke wheels, while the fairings were meticulously crafted using 3D printing technology. The sleek design showcases a pointed half fairing, a solo rear rump, and the iconic red Speedblock decor that Yamaha is known for.

Further accentuating the bike's appeal are sporty clip-on handlebars, LED lights, and various stylish elements. Although Yamaha is unlikely to release a similar model with a two-stroke engine or turbo, the RD Turbo serves as a dream come true for motorcycle enthusiasts. It beautifully combines the timeless charm of the Yamaha RD with contemporary performance, making it a true standout in its class.
