LighTech Oil Filler Cap M20x1.5 for Aprilia RS 457 (2024–2026) OIL101

Machined from aerospace-grade Ergal aluminium and finished to exacting tolerances, the LighTech OIL101 oil filler cap is the kind of precision component that sets a properly prepared Aprilia RS 457 apart from the rest — whether you are chasing lap times or simply refusing to compromise on quality.

Key Features

• CNC-machined Ergal aluminium construction delivers exceptional rigidity at minimal mass — a direct upgrade over the standard plastic cap
• M20x1.5 thread specification matches the Aprilia RS 457 oil filler precisely for a secure, leak-free seal
• Three safety-wire holes machined into the cap body allow straightforward wire-locking for track day and circuit use in line with pit-lane regulations
• Laser-engraved LighTech logo ensures authenticity and adds a clean, understated race aesthetic
• Outstanding heat resistance maintains an effective seal even under sustained high-revving road or track use
• Direct plug-and-play fitment — remove the OEM cap, thread in the LighTech unit, done

Built Without Compromise

LighTech has built its reputation in the paddock by applying the same material science used in grand prix racing to components that riders can actually fit at home. The OIL101 cap is milled from a single billet of Ergal — the high-strength aluminium alloy favoured throughout motorsport for its exceptional strength-to-weight ratio. Every thread, every face and every safety-wire hole is machined to tight tolerances rather than cast or stamped, giving the finished piece a rigidity and surface quality that the standard cap simply cannot match.

Track-Ready Detail

The trio of safety-wire holes is more than a racing styling cue — it is a functional provision for riders who attend track days where wire-locking of oil and coolant caps is a technical requirement. The holes are positioned to accept standard safety wire without fouling the surrounding engine cover, keeping your preparation straightforward. The laser-engraved logo sits flush with the surface so it resists wear and remains legible through repeated heat cycles and oil changes.
