Yasuni R-Pro Performance Exhaust with E-Pass – Piaggio 50cc

The Yasuni R-Pro is the road-legal evolution of the legendary Yasuni R — built for riders who want race-level performance without giving up street approval. Designed for 70cc sport cylinders but fully compatible with 50cc setups, it delivers up to 12 hp, excellent throttle response, and powerful acceleration from 10,000–12,000 rpm.

• For Piaggio / Gilera / Aprilia scooters (Zip, NRG, Typhoon, SR Motard, etc.) 
• Black sheet steel body with red aluminium silencer 
• ECE-approved with restrictors in header and silencer (removal voids approval)
• Spring-mounted silencer to prevent leaks
• Best results with 17.5mm+ carburetor and tuning CVT
