To activate the traction control and the launch control, change running map and apply fuel corrections on the fly a handlebar map switch is needed.

The Aim ECU can manage up to five maps that can be selected both by OEM Switches or even more easily by the AIM Handlebar Switch.

Taipan is the brand-new aftermarket plug & play ECU created by AiM, exclusively designed for off-road motorcycles. Thanks to its high technology 32-bit core, it represents an important step forward to improve the performances of your motorcycle, without sacrificing reliability and smoothness.

High technology 32-bit core
Engine control requires precision.
At 20,000 RPM the Taipan ECU guarantees a precision of 1/10 of degree: this means an accuracy within 0.8 µsec for turning the spark ON!
This precision is the key to guarantee:
A very consistent engine rotation.
The possibility to repeat dozens of tests at the bench always obtaining the same exact result.
A perfect reactivity at every minimum change of any point of a map and, at the end…
More power at the wheel.

The Handlebar Switch is the best way for changing the behaviour of your motorcycle; it features 2 pushbuttons and 10 LEDs and manages the following settings:

1) Change running map.

2) Apply fuel corrections.

3) Activate traction control.

Samco Hose Kit Key Features:

This is a high performance product which replaces your standard factory rubber hoses to a high quality Samco Sport silicone hose kit.

Thermostat Bypass hose kits remove the factory fitted thermostat from the cooling system, allowing better coolant flow and lower engine running temperatures.

Handmade in the UK and comes with a Lifetime Warranty ensuring you have the highest quality cooling products fitted to your motorcycle. 

Samco hose clamps will be included also.

If you select a KTM model the hoses will come in orange, if you select a Husqvarna model hoses will be Blue!

Thank You!

I received your kit to make my KTM 500 EXC-F the day after i ordered it ! Thank you very much ! We installed it that afternoon. I have to say when i bought this bike i was disappointed in how it ran but was told because of it being street legal thats how it has to run. Thanks to you this bike runs like its supposed to run.
