Speed Limiter

[esenior]

Was wondering first if the 2015 FZ6R has a speed limiter built in.

Now I know I am probably going to catch some flak for this, but I actually want to LOWER the speed limiter. My son is getting a bit too crazy on the bike and was hoping I could slow him down a bit by reducing the limiter (assuming it has one). Anyone know of a programmer or a company that can custom program a lower speed limit? Would prefer to handle this myself so that it can be easily undone later.

Thanks....Eric

There's none on this bike. The Australian version has a different throttle cable that won't let the throttle open pass 75% or so. Throttle cables are cheap and can be easily done by yourself.

Other than that... not much to do. The bike doesn't have enough HP to actually goes faster but if you change the gearing to +1 front / -3 rear on the sprockets (17/43) it kill the acceleration quite a lot.

You know your kid best. If your kid is not mature enough to understand that stupid hurt (LOL). Then sell the bike and get him a smaller one. I've been riding since I'm 6 yo and bought my first street bike at 36 yo. There was a reason why I waited so long... lol

Marthy's right, the aussie version came out as a learner approved bike ( power/ weight limit) which was just a throttle stop. This pic shows the difference, the bottom one is unrestricted, having a cut off stop allowing 100% throttle.

Here you go... time to sell your old stuff :wav:

This would be an expensive solution but it is an option.
The company is ecunleashed.com and they typically remove the factory ignition advance inhibitors from 1st, 2nd, and 3rd, then in some cases push the rev limiter out beyond factory settings.

That said, I would bet they may be able to reduce it too and keep it away from the happy spot.

The downside: shipping the ecu to a dealer/rep and the cost. They ding you $4 - 500 USD.

An option is used ecu (fleebay or a part out here), flash it to kill the joy and drop that in. Keep the original for later....

As I know it the older sibling the FZ6 the gauge retains the odometer info... these IDK!

Here in the UK/EU bikes sometimes have to be restricted to 35kW (47 horsepower). Why not but a restrictor kit online and fit that?

One like this will limit the throttle opening to around 50% and the power to 47hp.

Say if you wanted to make it a little faster, would it hypothetically be a bad idea to grind it down a little giving more power? I just want more kick from this bike

Are you in the US? If so then there would be no sense in grinding anything. At wide open throttle your throttle bodies are open as much as they could ever be. You cant get any more “wide open” than wide open.

It may be different in some countries that use a throttle limiter plate or whatever its called.
