I recently bought one for my KLX 250 Tuning of Rapid Bike Module.
For the characteristics I put the link to the manufacturer's website

Rapid Bike by Dimsport Technology - Additional control unit for motorbikes
Rapid Bike by Dimsport Technology - Additional control unit for motorbikes
Rapid Bike by Dimsport Technology - Accessories






It also handles auto-tuning

 

What does this module do?
Can you explain more about it?

 

This is a control unit as the powercommander for the Total Control Injection,
more in a single product is added to the auto-tuning, automatically changes the mapping.
It can be excluded without removing the harness by inserting a special connector to
his place and returns the original mapping.
The same unit can be mounted on any bike, simply replace the
wiring.

 

 

Neat.
This is for FI bikes?
Seems like a lot of moola for small gains.

 

It is only for FI bikes.
All this costs 260 € used, in Europe to buy a big bore kit there
want € 600-700.

 

I did chat to these guys about the rapid bike easy for my KLX. They were very helpful. They told me the Rapid Easy is designed to work with the stock exhaust system. They did say if you had the time to set the box up with a Dyno you may be able to adjust the trimmers to give max performance, but its was designed for the stock pipe. By this stage I had already put my gpr system on so I didn't buy one. They were reasonably priced too. If I had not bought an aftermarket system I would have bought one.

 

Mine is a Rapid Bike EVO, can be adapted to all exhaust system,
and is installed on all bikes only replace the wiring.
