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.

Performance deCAT kit for EURO5 models containing a set of big bore header pipes and 2-1 connecting pipe (H pipe) without CAT. The big bore downpipes improve exhaust gas flow resulting in improved torque and power though the rev range. The dowpipes are 50% lighter than the originals and combined with the 2kg weight saving from the mid pipe you'll see a noticable weight saving. Also available with a CAT by special order - enquire for details. This kit will also improve the exhaust note but for optimum results combine with a Mistral performance silencer and air filter SIA10433. We also recommend fitting a V-Twin Boost plug-in FUA85001 with this CAT eliminator to enrichen the mixture

• CNC exhaust flanges included
• Significant weight saving
• Top spec AISI304 stainless steel (no rust!)
• Y piece is compatible with original heat shields and lambda probes
• Installation with graphite bushings to limit the transmission of vibrations
• Fixing bracket with antivibration silent block
• Straight through design for better performance and deeper sound
• Larger diameter internals for better exhaust gas flow
• Crossover is compatible with original system components
• Reduces engine operating temperature for better fuel consumption and efficiency
• Includes exhaust bushes (normal cost £30) and exhaust header gaskets
• Manufactured on the shores of Lake Como and developed using a rolling road

HIgh performance aluminium velocity stack for airbox to throttle body union. 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 - SIA10433 and V-Twin Boost - ACA85001 or ACA85002.

Customer Kev fitted this combo and called us the next day to say that his V85TT was transformed; the fluffy throttle response between 2k and 3k was gone and the engine pulled better. Simple to fit, installation time is less than 30 minutes and the battery does not need to be disconnected.
