As title, is it a noticable improvement or just a gimmicky device?

 

Noticable improvement definately not a gimmick.

It's a fact that Suzuki tame the GSXR down in the lower gears. TRE eliminates that

 

yes i agree defo work had one on my old k2 600

 

if you're gonna be riding fast its a must in my eyes,it stops my gsxr 1000 cutting out at 186mph

 

Update: Got a switchable one now, chuffed, totally transformed the bike. Much better power delivery and the de-acceleration is far less harsh, much much nicer to ride all round but especially 1st and 2nd

Cheers for the advice lads
