This is a MX King / Y15ZR FFA 300cc full drag setup, designed to replicate the behavior and feel of a real drag race engine. There’s no idle speed (engine immediately revs up on start), with extremely fast throttle response, and a realistic, aggressive drag exhaust sound — raw, high-pitched, and screaming at top rpm. Engine Specifications: Configuration: Single cylinder, 300cc (Full FFA build) Bore x Stroke: 74 mm x 68 mm Crankshaft: Lightweight drag-spec crank, low inertia Camshaft: High-lift harmonic cam, 230° duration Compression Ratio (simulated): ~13.5:1 Fuel: Race fuel (120 RON) Exhaust System: Tuned short megaphone pipe Redline: 14,500 rpm Transmission: Close-ratio 6-speed drag gearbox Final Drive Ratio: 6.3 Vehicle Weight: 95 kg (simulated total)
