Timing Retarder Eliminators - (TRE)

Turns itself off when in neutral so idle quality is unaffected.

(see fit applications below)


The "Smart TRE" requires no adjustments to idle speed or fuel mixture to maintain smooth idle quality, it also will not disturb the cold start fast idle quality.

I have never seen so many differing opinions about how this little, inexpensive device operates and affects your bike!! So, I have decided to address some of the functions and try to clarify it's use.

The TRE is a device which allows much better throttle response in the first 4 gears on all EFI Suzuki sportbike models.

What the manufacturer has done is to make a SEPARATE IGNITION MAP FOR EACH GEAR.

However, it limits the power and smoothness of your bike in the first 1/2 turn of the throttle in gears 1 through 4.

They were clever in the design of this timing retarder. It still allows full timing advance (at full throttle) in all the gears.
As you shift up through the gears, the amount of throttle needed to access the advance curve decreases, until you make it into 5th gear and then it's gone. You have nice, smooth operation. Wouldn't you like your bike to respond just as smoothly in the lower gears?
The TRE will not give you more power at full throttle on all Suzuki models.

That is why I invented the TRE and also coined the name as well !!

This product offers a nice improvement to driveability and makes the throttle response more predictable !!

I am the the original inventor of this product !!

I made them in my shop since 1997 for individual customers bikes TL1000s and GSXR750 models

I first released it to the public in a pre-production sale on in the fall of 1999.... the rest is history !!

My TRE product was tested in all the magazines at one time or another and was always rated with high marks.

I couldn't stand how these particular models ran in traffic. In addition, while going into a curve and closing the throttle in 2nd or 3rd gear the engine would come back with a big jerk when reapplying the throttle. After my TRE installation, gear changing was much smoother.

The TRE will disable the top speed limiter on these Suzuki models:
2001 thru 2015 GSXR1000 and
2001 thru 2015 GSX1300R

This due to the fact that the ECM does not see the the top gear ignition map, which has an earlier rev-limiter.

The TRE will not allow your speedometer to read higher than the ECU will allow it to.
