IRC Components Up & Auto-Blipper Down Quickshifter for Aprilia RSV4 and Tuono V4 (APRC models only 2009-2010 AND all models 2011+) with "Strain Gauge Sensor" Technology allows for Full Throttle Clutchless Up & Down Shifting. MotoGP certified by Magneti Marelli state-of-the-art load cell sensor with both right and left dual "Magic" threads". The IRC Components ELECTRONIC quick-shifter has a major advantage over other units in the market because it dynamically considers the RPM and Acceleration to modify the Cut Time ("T") and Pulses Power Progressively eliminating gear box shock which is helpful during cornering or braking to prevent upsetting the chassis that can lead to a loss of traction or change in the bikes trajectory (this means you can up-shift or down-shift while cornering). The intelligent controller of the IRC quick-shifter is directly connected to the load cell; signal handling is extremely precise and controlled. Easy to install Plug & Play bike specific wiring harness and shift rod (M6-M6 / 165mm) included. Standalone System does not require a Piggyback Fuel Management System.
Adjustable pre-load settings (via Two-Buttons on Unit) allow the rider to customize six (7) settings making shifts seamless and smooth versus "switch units" which can be harsh: 1. Cut Time ("T"), 2. Minimum Downshift RPM ("RL"), 3. Downshift Speed ("SL"), 4. Upshift Pre-Load ("L"), 4. Minimum RPM Limit ("SR"), 5. Downshift Timing ("TS"), 6. Downshift Pre-Load ("LS"), 7. Push or Pull ("CE").
IRC Quick Shifters are Non-Homologated for Professional Closed Circuit Use. Sensors are certified to over 1,000,000 shifts and all kits are 100% tested for performance at the end of production. Made in Italy.
