GTR-Spec: A Yamaha Scooter with a Supercar Soul

The builder took a holistic approach to the powertrain. Instead of chasing peak horsepower, the goal was a balanced and responsive package for urban riding. The engine’s breathing is managed by an aRacer MINI XX ECU, paired with a street-legal 'Octopus' brand exhaust system. To ensure the power gets to the ground effectively, the entire driveline has been upgraded with a full SCRK transmission kit and a corresponding G-Stone gear set. This focus on a complete system, from fuel management to final drive, suggests a mature tuning philosophy aimed at creating a reliable, rideable, and exhilarating machine.

"The core idea was to merge the iconic McLaren P1 GTR livery with Yamaha's own 60th-anniversary checkered flag speed block aesthetic."

The scooter's aggressive, stretched-out stance is its defining chassis characteristic. This look is achieved via a 10cm swingarm extension mount, pushing the rear wheel back and creating a long, low profile. Handling duties are managed by a premium Öhlins YA186 rear shock, while the front forks have been internally lowered to match. Braking is seriously upgraded, with a Brembo 484 caliper and 267mm FAR disc up front, and an RPM 'crab-style' caliper at the rear. The build rolls on 13-inch MOS FS20 wheels, fitted with a significantly wider 150-section rear tire that adds to the muscular posture.

The core concept comes alive in the paintwork. The primary yellow-and-black theme is a direct homage to the McLaren P1 GTR, but it’s layered with Yamaha’s 60th-anniversary "speed block" checkered flag motif. This fusion of automotive and motorcycle racing history is expertly applied. Up top, the stock plastic handlebar shrouds are gone, replaced by an aggressive JSTC 'Nighthawk' handlebar clamp and riser setup, exposing the controls. The rider’s view is now dominated by a KOSO RX4 digital multi-function display, providing modern data in a clean package that complements the build’s technical focus.
