Hey, hope everyone's ok.

Just looking to get an idea of how much it would cost to restrict a Honda NSR 125 if I bought a full power model.

Could the procedure be carried out at a local Honda dealers or bike shop, and what sort of paperwork would you have to fill in or change after you've restricted the bike?

Many thanks,

Mark

It could be done yes but if your going to be riding legally why bover with the nsr and get the cbr, unless you really want the nsr. Or just don't restrict it and ride it anyway like most of the people with 2stroke 125s.

But yes honda could do it and im sure they will bend you over for the pleasure of making your bike slower.

There is no paperwork.

Best bet would be to get a restricted exhaust; that or just get a washer welded in there.
Should be able to find the carb-restricter fairly easily from someone that has derestricted.

The CBR is too small...I haven't had the chance to sit on an NSR yet, but I'm hoping it will be ok. I'd look forward to the point when I'm able to restrict the bike after I pass the full test, but to start off with, I'd rather be safe than sorry to be honest.

Oh right, ok. That's cool.

So what's actually used to restrict the bike, what makes it restricted?

A washer in the exhaust and a plate between the carb and in-let, as described above.

Myself, I'd just leave it de-restricted.

Ok, I'm with you...thank you.

I guess it's an option, but how easy would it be to get caught?

What would happen if I took the bike to get serviced but they see its a restricted bike with L plates?

The garage will do nothing if they know the bike de-restricted as its not really any of there business. They wouldn't call the police or stop you from ride off on it. The chances are they wouldn't even know. As for the police there is again a very slim and i mean really really really small chance of you being caught, doesn't mean it doesn't happen or it hasn't happened but ultimately its up to you and yes it is possible for being caught.

Ok, thanks...I'll bear that in mind.

To start off with, I'm not really going to be worried about speed anyway. I'm just looking forward to being able to ride the bike. The best option might be for me to buy a bike that's already restricted, and then I can derestrict it after the full test.

Thanks for your quick responses,

You got to be carefull if you buy a restricted nsr though. Since it could be a import basically depending on where it is from it could be near impossible to de-restrict or very easy

have a quick read though that
https://en.wikipedia.org/wiki/Honda_NSR125

it explains it more.

I don't really know alot about the bike but there are some experts on this site if you need to know anymore info.

and yes i have no life Crying or Very sad lol

Lol, it's ok. I'm grateful you're around to help.

Read the Wikipedia article, the de-restricting does sound fairly complicated. It sounds as if I buy a restricted model I'd definately struggle to de-restrict it after passing the full test. The only issue is whether I risk the fact of riding a de-restricted bike when I'm not supposed to.

It's definately something to think about, but at the moment I'm not sure what to do.

Thanks for your help, Thumbs Up

As a point I will be selling my NSR soon, probably selling it de-restricted. I still have the restricted exhaust intake and a carb restriction, also the original carb jets, so if the new owner doesn't want them I can let you have them ^^.

Carb intake is simple to put in, very simple. The exhaust restriction would need welding back in though. Carb jets is an easy one to do as well.

All in all.. Not so sure I'd ever want to ride a restricted NSR the power difference is.. not massive I'll be honest with you. I did put lower gearing on it which meant it went from topping out at around 75 it went up to 90. But acceleration is rather different.

why restrict an NSR125 I have a full power one (doing nothing) and to be honest it isnt all that faster than a restricted one.....anyways why would you tell in the fisrst place I rode on one for 2 and half years and no one knew any diffrent..

Just ride it. Everyone rides derestricted 125s - except those who ride 125s that cannot be derestricted.

Its more hassle than it is worth to re-restrict an NSR. The difference in power is something like 5bhp anyway. Its worlds away from riding an unrestricted 100bhp 600 when you're supposed to be restricted to 33bhp.

Thank you both of you for those really nice offers. I'm extremely grateful, I wasn't expecting that at all, but to be honest it's still a long way off at the moment. I'm just spending a lot of time thinking about the best options...probably thinking about it too much, but I'm prone to overthinking about things.

I'll probably try and give it a rest for a little bit and try and take it as it comes. I'm probably getting too excited when I've still got a long way to go.

For now, I'll probably say one of the simplest options would be to get the restricted bike so I'm riding legally and then have to cope with the problem of struggling to de-restrict it when the time comes. Thinking about it though, when I'm at the stage of being ready to take my full test, I'd hopefully be in a position when I've got some money saved up to start looking for a bigger capacity bike, so there would be no need to restrict the NSR.

Thanks so much for your help though, it's really appreciated. Thumbs Up

Cool yeah, it is always best to think things through first, but odds are I'll still have them kicking about in the garage in a few months or longer so if your in need still send me a message and I'll let you know if I've still got it ^^.
