According to the Aprilia RS 457 Official Use & Maintenance Manual Specifications, the 2024–Present Aprilia RS 457 (chassis ZD4KSA00/KSA) requires 2 L (2.11 US qt) of SAE 10W-50 (JASO MA2, API SN Fully Synthetic (Castrol Power1 Racing 10W-50)) engine oil for a drain-only change and 2.2 L (2.32 US qt) with filter service (1A023538 / HF138). Standard solo cold tire pressure is 200 kPa / 2.00 bar / 29 PSI front (110/70 ZR17 M/C 54W) and 200 kPa / 2.00 bar / 29 PSI rear (150/60 ZR17 M/C 66W), paired with 2× NGK MR9DI-7 spark plug(s) and a ETZ9-BS / YTX9-BS battery.
Drain only: 2 L (2.11 US qt)
R 200 kPa (2.00 bar)
Est. Range: ~317 km (197 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Debuting for 2024+, the RS 457 hits the exact 35 kW (47.6 hp) A2 ceiling while standing out as the only twin in its class with a cast-aluminum twin-spar frame, ride-by-wire throttle, and 3-level traction control.
Oil & Clutch Mechanical Engineering Note
Scaled down from the RS 660 architecture, the 457cc 270° twin specifies full-synthetic SAE 10W-50 JASO MA2 oil (2.2 L) and shares Aprilia’s 1A023538 / HF138 (M20×1.0 pitch) spin-on filter—checked warm via a crankcase sight glass rather than a dipstick!
Garage Wrenching Gotchas
- Critical thread-pitch warning: Aprilia’s 1A023538 / HF138 spin-on filter uses an M20×1.0 fine thread—NEVER try to thread on a Honda/Yamaha HF204 (M20×1.5 coarse pitch) even though the canisters look identical!
- Aprilia’s manual specifically warns against idling on the stand to check oil: verify the sight-glass level upright on flat ground immediately after a 15 km (10 mi) warm-up ride.
5. Frequently Asked Questions (FAQ)
How much oil and which filter does the Aprilia RS 457 require?
An oil and filter change using Aprilia OEM filter 1A023538 (or Hiflofiltro HF138) takes 2.20 L (2.32 US qt) of full-synthetic SAE 10W-50 JASO MA2 oil.
Why is the RS 457 cold tire pressure set to 29 PSI front and rear?
At just 175 kg wet with an aluminum frame, Aprilia specifies 200 kPa (2.0 bar / 29 PSI) cold front and rear so the 110/70 and 150/60 radial carcasses warm up and flex properly.
How aggressive is the riding position and 800 mm seat height on the RS 457?
With clip-ons mounted just above the upper triple clamp and a narrow 800 mm saddle, it balances sportbike track feedback with comfortable wrist ergonomics for daily street rides.
