performance upgrades


Most modern motorcycles are restricted in one or more of the following ways:

  • Decreased Ignition Timing at High RPM and/or Lower Gears (1—2—3—4)
  • Limited Hard Acceleration by Restricting Secondary Throttle Blade Opening
  • Reduced Peak Power Output by Limited Ignition Timing and/or RPM
  • Top Speed Limit or High Gear RPM Limits

These restrictions are used to control power output to allow easier control of the motorcycle for street conditions. However, these will limit the full potential of engine for racing use. Allow us to eliminate these restrictions and allow your engine to run the way it should.

What is ECU Reflashing? ECU stands for "Engine Control Unit." It is the computer that takes information from the various sensors on the engine like crankshaft RPM, manifold pressure and throttle position to determine how much fuel to deliver through the fuel injectors and when to fire the ignition coils.

The computer "chip" that is the heart of the ECU is usually an EEPROM —— an Electronically Erasable Programmable Read Only Memory chip. The Read Only part of that means the chip retains its programming without periodic electronic refreshing; loss of electrical power doesn't lead to the chip losing its programming (It's I" the CMOS BIOS of a computer). "Flashing" the chip involves electronically erasing the read only program and replacing it with new, updated information (the engine control 'map').

What does it do? Our reflashing services remove restrictions that the OEM's have programmed to meet government regulations and that reduce throttle respo and power output for novice riders. Early speed and RPM limiters, reduced acceleration and limited peak power output are all ways the manufacturers have restricted these motorcycles. We adjust these settings to unlock the full potential of your engine. Find your make/model below to see all the features we include with our services.


Air Shifters are used to allow fast mechanical shifts with the use air.

A shift cylinder is attached to the motorcycle shift mechanism either by the shift lever directly, or by an additional bracket. A solenoid valve controls the air supply to the shift cylinder via the compressed air source, such as an air tank in the swingarm/chassis or a regulated high pressure supply. When the rider wants to make a shift, a button is pressed that gives a signal to the solenoid to open. This causes the compressed air to enter the shift cylinder and push or pull on the shift mechanism just like the rider's foot normally would.

Another key component that is required is an engine power cut. This is commonly called a "kill box". This works by momentarily cutting the ignition or fuel supply to the engine for a very brief period of time (30—90ms) while the air shifter is activated. This allows the transmission to shift into gear without the use of the clutch.

Since all shifting is done with an electronic signal, you can can wire the bike to automatically shift at a preset RPM with the use of an RPM activated switch or a shift light with autoshift output

Most riders prefer to use the stock horn button as their air shift activation, which is perfect since Schnitz Racing offers wiring harnesses and instructions on how to do that.
