Smooth that throttle AND achieve better fuel economy!

The Motocorsaro O2 Optimiser allows you to adjust the Air/Fuel ratio into the closed loop fuel injection circuit on compatible Aprilia V-Twin models, giving the following improved fuelling characteristics:


Smoother Throttle Response (particularly low RPM on/off throttle transition)

Sport Mode - in particular on many models, gives savage & unpredictable low RPM throttle response/surging.  Always annoying, but sometimes downright dangerous! This modification gives far smoother control, noticed particularly in slow/medium speed turns and in traffic, when the bike's balance is upset from the abrupt/harsh reaction to small throttle adjustments.

On the standard bikes, most owners resort to riding in Touring Mode, as the throttle surging in Sport Mode is so severe.  After fitting this, you’ll want to use Sport Mode all the time and actually enjoy your riding again!

Reduced or Eliminated Surging 
More relaxed riding and more predictable overall throttle control.

Reduced or Eliminated Popping & backfiring on closed throttle (overrun) due to lean fuellingThis characteristic will be further exaggerated if you have replaced the standard exhaust, catalyser and/or air filter.  

Improved Fuel Economy

Fuel consumption will also improve after the unit is fitted, from testing, expect in the region of 4-7 mpg.  This is further reinforced by my own personal experience.

Fitting is straight forward 'plug & play'.  No wiring requires altering or cutting.  The unit simply connects between the existing OEM connectors.  The unit can befinely adjusted if you feel the need. However by VERY SMALL increments. The recommendation though, is just to leave it set at the pre-calibrated position initially, ride for at least 20 miles, then adjust from there.  Just follow the instructions.

Instructions are included as Ebay message support.  The unit is specifically designed for for the harsh U.K. climate and is resistant to water ingress if installed as recommended.  It was developed and thoroughly tested by a daily London commuter, on his Aprilia Shiver and by many other riders worldwide - to universal praise of the improvement it makes. 

The unit comes with comprehensive fitting & set-up instructions and zip ties.  The unit will work in all operating conditions, climates and elevations irrespective of what other tuning modifications you have fitted.  Just follow the instructuctions.
