Aprilia RS 125 Guide: Maintenance Tips & Unleashing Full Power

Aprilia RS 125: The Track-Day Master

⚠️ SAFETY MESSAGE: The Aprilia RS 125 requires strict maintenance. A top-end rebuild (piston and rings) is recommended every 10,000 miles to prevent failure. Always ensure your oil pump is adjusted correctly to provide the right mix for the high-revving Rotax engine.

The "Reliability" Fixes

• Gearbox Oil: Use only high-quality 75W-90 or 10W-40 motorcycle-specific oil to protect the internal nylon balance gears.

  • Shop Motul Gearbox Oil for Aprilia RS 125 on eBay

• RAVE Power Valve Blade: The power valve is prone to sticking. Clean it frequently or replace the blade and cable if they show signs of wear.

Easy Performance

• Full Power CDI: If your bike has the "environmental" dip in power at 6,000 RPM, a de-restricted CDI is the best fix.
