TRE, has any body fitted one of these ? and do they work ?

The TRE (Timing Retard Eliminator) is a device that allows much better throttle response in the first four gears on all EFI (Electronic Fuel Injection) Suzuki sport bike models. What the manufacturer has done is to make a separate ignition map for each gear. This has been done for either safety (Wheelies/wheelspins!) and/or emissions reasons. However, it limits the power and smoothness of your bike in the first ½ turn of the throttle in gears one through to four. Quick facts about the TRE:- The TRE has no effect at full throttle; The TRE does have an effect at throttle openings up to ½ in gears one through to four at any RPM; The TRE does NOT affect full throttle power - This has been verified on the dyno as well as on the road under controlled conditions; The TRE is legally for race use only. The TRE will work in all these models: Suzuki SV650 & DL650 (V-Strom) 2003 & up only; NOTE: All Timing Retard Eliminators comes with full installation instructions.Some cutting or splicing is required.

From what I understand, it makes no real great differance; and anyway, if its only affecting the first half throttle turn, then just open the throttle some more, surely?

yeh, i know what you mean, just wondered what it was all about, mine revs ok in first 4 gears, and the rest lol, so not sure what it does, strange.....may be just another gimmick, but i bet someone on here has fitted one, just wondered if they noticed a improvement, in something, lol

Yea, a few people have done this modification. It may have some use on the track, and possily works best in conjunction with a quick-action throttle, but I don't think it'll make much noticable differance.

Restrict your bike for 2 months to 33 bhp, then derestrict it....suddenly, 70 bhp feels quite alot!

Don't think it has much of an effect on the SV, but on some other 1000cc bikes it has a much bigger effect.

stormer - i think your right there! I wonder what the power is "limited" too on say a GSXR1000 in the lower gears?
