HIgh performance aluminium velocity stack for airbox to throttle body union on single throttle body models. This velocity stack replaces the standard part with an aluminium part that protrudes into the airbox. Through careful design it improves the engine response by providing an increased volume of less turbulent air to the throttle body. No modifications are required to fit this velocity stack but you should see a torque increase of around 6% at 2500 RPM and 3% increase in power at 6500 RPM

This manifold is suitable for EURO 4 and 5 models, manufactured on the shores of Lake Como. Developed for optimum power and torque on Mistral's rolling road. For best results combine with a performance air filter - SIA10434.

Simple to fit, installation time is less than 30 minutes and the battery does not need to be disconnected.

This adjustable fuelling modifier uses the lambda sensor signal to the ECU. By modifying that signal it achieves an improvement in low and midrange throttle response. Comes with wiring harness and instruction manual, installation is simple and does not require any specialist tools. Suitable for all single throttle body V7, V9 and V85 TT models.

Rapid Bike EASY: A base level simple plug and play modulator equipped with a microprocessor managing the lambda sensor signal to optimize the air/fuel ratio, improve the engine efficiency and eliminate power gaps typical of the low and medium rpm range.
