4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Aprilia’s urban adventure scooter featuring long-travel Showa suspension (120 mm front), 175 mm ground clearance, wide naked handlebars, and a 14.75 hp Euro 5 i-get liquid-cooled single.
Oil & Clutch Mechanical Engineering Note
Powered by Piaggio’s liquid-cooled i-get 4V dry-CVT powertrain, requiring 1.3 L of synthetic SAE 0W-30/5W-40 with spin-on filter 82635R plus 220 ml of SAE 80W-90 rear hub gear oil.
Garage Wrenching Gotchas
- Tuned right to the 14.75 hp A1 limit, sustained full-throttle commuting warrants 4,000–5,000 km oil changes and regular threaded-in dipstick checks on the centerstand.
- At 799 mm with wide adventure floorboards, stand-over reach feels tall—dial the 5-step rear twin-shock preload properly for solo vs two-up riding.
5. Frequently Asked Questions (FAQ)
What are the engine oil and rear hub gear oil capacities for the Aprilia SR GT 125 / SR GT 125 Replica scooter?
With an isolated dry CVT belt case, the engine requires 1.15 L drain-only or 1.3 L (1.37 US qt) with filter/screen (Piaggio 82635R / HF183) of SAE 0W-30 (JASO MA2). Service the rear reduction hub separately (final drive 220 ml).
How do you accurately check the oil level on the SR GT 125 / SR GT 125 Replica, and what are its service intervals?
After warming the engine and waiting per manual procedure, thread the dipstick all the way in before removing it to read the oil level (resting it unscrewed causes overfilling). Torque the drain plug to 24 N·m with a new crush washer. Factory oil change intervals are every 10,000 km, with valve clearance inspection every 20,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the SR GT 125 / SR GT 125 Replica?
Fitted with 110/80-14 53P front and 130/70-13 57P rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 29 / 32 PSI (200/220 kPa) solo or 29 / 35 PSI loaded. Seat height is 799 mm (31.5 in) at 144 kg wet weight, delivering ~360 km per 9 L tank.
