  • de-restriction

    Evening all

    Ive now had my V reg (2001) tl1000s a few weeks and love it to death!!

    A mate at work has a 97/98 tl1000s and was saying the other day that my tl was de-restricted to calm it down abit from the early models, is this true??

    Ive seen for sale a nikkon plug in de-restrictor that adds more power to 2nd and 3rd gears. Has anyone ever used one of these and if so is it worth getting??

    Cheers guys.

    Re: de-restriction

    Put your location in your profile so we can at least see what country you're in.

    Terminology. They restrict them to calm them down. De-restrict them to remove those restrictions.

    The '97 had some performance features, as well as some problems. Some people view those changes as Suzuki restricting them, but IMHO not really.

    Some countries have different ECUs, cams, plugs in the throttlebody bores, etc. to restrict the HP.

    They all come with ECUs that change maps, mostly igntion timing, by what gear you're in. You plug in a TRE (timing retard eliminator) to make it always think you're in a full-power gear yet let it change maps for neutral and clutch disengaged. A "smart" (keeps neutral/disengaged map function) TRE improves partial-throttle response in 1st thru 4th.

    There is no mph speed restriction on a TL.

      good answer

      It never ceases to amaze why people ask for advice then when I give it they either ignore it or argue against it.
      But then I don't know all that much about TL's

      wwjd.......what would jimmy do.

Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."

          Unless it's using an ECU for the Japanese market. They were speed limited to 180km/h. (~110mph)

            I thought the ECU doesn't even have any connection to the sprocket speed sensor, I thought the wire went directly to the speedo/mileage guages. Did the Japanese ECU limit the RPM in 5th and 6th? That would be an RPM limiter and not really a speed limiter. Most countries that restrict them restricted the HP. The ECU doesn't really know how fast you are going.

              Yes, the rev limit was lower in the upper gears (4, 5 & 6 IIRC) - the actual speed itself isn't measured, it's theoretical. (Although even if the speed was measured, the limiting would be done by lowering the rev limit - not by applying brakes or closing the throttle or something, so all the speed limiters are rev limiters at the end of the day).

              Exactly the same as the 'speed limiter' on GSXR1000's and Hayabusa's, for them it's a lower rev limit in 6th gear.

              OK so the Japanese bikes were limited to a "theoretical" top speed of 180km/h ~110mph and it's not a speed limiter. At the end of the day, if you fit a Japanese market ECU into your bike it won't go faster than 180km/h with standard gearing. They also scored a smaller exhaust outlet diameter too.
