Large-Bore PWK Sleeve – Derbi, Aprilia SX, Gilera

Crafted in our own workshop, this large-bore sleeve connects your PWK carburettor from 19 to 34 mm to the original or full-power air box on Derbi, Aprilia SX and Gilera. Its strength? An easy fit that lasts over time.

Built to resist heat and fuel, it gives a clean, durable link between the carb and the air box, with no play and no leaks.

Benefits:

• 🔊 Clearly reduces engine noise
• ⛽ Lower fuel consumption
• 📈 More torque and acceleration
• 🔧 Easy fit on the air box
• ⏱️ Long-lasting, resists heat and fuel

Note: fits exclusively with the LRT Performance evo 2 intake, which delivers a real top-end gain (dyno-proven). The full-power air box is sold separately on our site.
