Racing Intake Pipe B1 — Manufacturer reference: D733B0500B
Designed for road and track preparations, this B1 intake pipe is aimed at riders looking for a more direct intake for high-performance setups. With an inner diameter of Ø 34 mm, it is intended to accommodate PWK carburettors from 24 to 28 mm, in order to improve fuel flow and engine responsiveness during acceleration phases.
Racing product designed for Urban, Cross, and Roadster environments. Ideal for preparations based on 50 cc and swaps requiring optimised intake. Carburettor/reed valve installation and adjustments are necessary to take advantage of a more responsive engine.
Important note: For installation on a Derbi engine for Racing use, modification of the crankcase and installation of a V-Force V381S reed valve box (Bihr p/n 1009766) are required.
