Advise on restricting engine power please?

I am looking to handing down my 2009 ZX10R to my wife...but she is a new rider and I want to restrict the engine to 33hp, with the option of 60hp, and 120hp as she progresses. I would also like to be able to completely destrict it at will, when I plan on taking it out for the odd track day myself.

This would probably have to be an ECU modification....can anyone advise if this is even possible and if so how to go about doing it?

I would love if I could set up some sort of power switch like they have on the new 1L bikes...the ones that have rain mode, sport mode and race mode.

Any advise would be appreciated.

Easy. Get her to start on a 250 and move to the liter bike when she's comfortable/confident enough...

Your best be is to look to the UK for the restrictors new riders have to use. I doubt you'll find anything to dial-a-hp, but they have restrictors that new riders require when starting on a SS.
 
Why would this be a troll?

If you must know....I have a finance on the ninja, yet I am also picking up a new bike. Rather than sell off the ninja at a serious loss, I would rather modify it (if that is even possible). I know the UK has restrictor kits to 33bhp which is largely driven by their graduated licencing laws. I am getting more info from a company out in the UK on their restrictor kit...but I was curious if anyone knew of restrictor kits here, especially with a variable cap.

We have already looked at 250cc bikes, but it doesn't seem like a smart financial move to sell at a loss, then pick up a low capacity bike, which she will probably sell off in a couple years time. Plus I would rather keep the bike as part track bike, part back up, and as she wont ride as instensely as I do, it isn't worth selling off.

I understand it is a highly specific mod, but I fail to see how this qualifies as anything troll like.

Anyways....the 2009 ZX10R is fairly high spec, electronically I mean....I would imagine there are some mapping restrictions that can be applied to the ECU. But this is not at all something I am familiar with, hence the request for advice.

Is there a possibility of having it remapped to be highly restricted?
 
I might be blunt here but if she can handle the weight of the ninja then trust her with the power, she should also trust her self not to roll in on the throttle as much knowing the bikes abilities.

The only safe way is a smaller bike. Hate to say it bro but, that bike is not light and dropping it is a real possibility for her. Unless she's some body builder! lol If she's intimidated by the bike bc of the HP then that's not a feeling she should have getting on it either.

Taking a loss on the bike bc you are eager to get a new one yourself doesn't reason to jeopardize her safety. Just my nickel thoughts.
 
By the way...what makes this topic interesting is that in the UK, you can have a larger cc bike restricted and it will qualify for legal usage by a graduated licenced rider. In this way, a new rider can buy the bike they actually want, rather than a small selection of gutless bikes they expect to sell off in a year or two.

So you can buy the bike you actually want, have it restricted, then grow up with the bike, destricting it when you're ready to move on. The restriction kits come with certifications and the dealers are obliged to keep any components that would allow you to derestrict them prematurely.

Now in Ontario this could be important if insurance companies would consider it...that way new riders could get the bike they want, restrict it and get a better insurance rate. At the moment it's just my wishful thinking, but with the increase in insurance rates, I wonder if this might be an option in the future. While in the UK, there is a better collection of low capacity bikes on offer, we all know how limited the low capacity range is here.
 
I would expect it to be damn hard to get a fuel map that works that limits the bike to 33HP. Your best bet is likely an adjustable rev limiter (ie. roughly 3.5K,5K, 7.5K for the power levels you mentioned). This keeps the power under control and you don't need to worry about different maps (but you would need to shift a lot). Alternatively, restriction in the intake (and remapping) could work, but would be a pain to adjust. The third option is the one used by places like gtaexotics where they restrict the movement of the throttle so you get the entire rev range, but are limited to 50% (or whatever) throttle. Not sure how easy it would be to make this quickly and easily adjustable.

The 1000 is relatively heavy and any solution will likely have significant compromises, I will add another vote for buy a 250. (Keep the 1K if you want for all the other reasons you listed)
 
Take out 3 spark plugs and put one in when you think she's good to handle more power till she's cracking out wheelies on 4 plugs

The weight isnt too much of an issue. I started on an '88 FZ600 with around 62 hp and weighed nearly 410lbs dry! The modern Litre SS are less! The Ninja is 430 lbs wet. Also the weight could help when it comes to wheelies (if restricted). When I first did my M1 exit course back in the days, we had options of various bikes. I somehow managed to accidently wheelie a Honda 250 sport bike! But yes, she is likely to drop it, but that is expected. I am not too bothered if she drops it at low speeds. I expect this bike to get some abuse as my occasional track bike and her learner bike (if it works). Even most men have serious trouble saving a low speed drop, so I am not expecting her to save it just to avoid some road rash on the bike.

But you're right, my primary issue is (relative) safety. If it works out that restriction provides a linear smooth power delivery, and I can lower and soften the suspension, aaaand I can relax the brakes, then it may be a serious option. The weight I am not too concerned about....I see plenty of girls on 600R's these days, and there is not much more than 10lbs difference between those and my ZX10R!!! By the way, the wet weight of a 2012 Ninja 250R is 375lbs!!! That's 55lbs difference between that and the 10R!!!

I'm not convinced weight is an issue. My main issue is the abrupt snappy nature of the power and braking along with the torque and peak power. I know below 5000rpm the bike is rather sluggish and there isn't a risk of wheelies or sudden explossive power, and I feel restricting the rpm to 5000 would make a capable learner bike....that would let it get to 120kms in 6th gear.

are YOU NUTS
 
Even better, just put a 250 throttle cable on, that will restrict it to 1/4 power

Any idea where to get or have installed a variable adjustable rev limiter in the GTA?
 
You have to change where the throttle cable connects.

eg:

Don't know it if is a crazy idea (yet), I am exploring it as one of many options. I am an advocate for graduated learning, and I am not interested in putting my wife at risk...I am just exploring an option here to see if it is viable. It is not an explored option in Ontario, but is something done in Europe, so there is some merrit to it.
 
Hey here's a crazy Idea, How about NOT getting your chickiepoo a god damn liter bike as a first bike!

Just thinking out of the box here

This is a modified part or a manufactured part? Any idea if this is made for different bikes, ZX10R in particular? So it seems the power delivery can be altered by the arch of the part itself....interesting option. I imagine the location of the end bit would also limit the peak hp, but I wonder if I could get this part in various restriction levels...this way I could swap them out as she improves and is ready for more power.
 
try making the gap on the plugs smaller. it should reduce the power
