How to install motorcycle restrictor (Carb'd bikes) 

Keith1212 its only for new riders for 2 years under 24

Should remain the same, just less is going into the engine

+Simply Electronics thanks for the reply. Im from Denmark and here we need the certificate to show at a service inspection of the bike

@@lazze13 in the uk you could just write one up yourself XD

a restricted 650 still feels stupid powerful compared to a 125cc or 250cc

Yeah just take them out when you want to de restrict it

The restrictor arrives in a few days, I'll hopefully be giving it a go when it arrives. I'm afraid I'm gonna mess something up haha.

LeeShawBrown how was the fiting on the bandit, that gonna be me very soon. how was it to do?

SV is a better bike

It will still redline as normal, very little change in sound. But in gear it will just won't pull as hard so your acceleration will be weaker and your top speed will be restricted. But it doesn't take away from the fun if you don't know what your bike is like de-restricted. Don't try it either because you'll then be tempted not to restrict it. Top speed on my SV650S wouldn't do above 100mph when restricted. Derestricted it will do 135mph.

most A2 bikes will do a 5sec 0-60 and around 100-120mph top speed which is fast enough for 2 years while you improve your riding.

I never did, It was running ever so slightly lean but wasn't a problem. Just see how it runs, check for any stronger smells of fuel or any erratic behaviour after installing. If you want to rejet, you can do so.

you'll just have to have a look. Post 2016 bikes use electronic restrictors, such as a restricted ecu. pre 2016 can use mechanical restrictors which will either be washers in the intakes, such as the one in this video, or restrictions on the throttle grip/body which stop the throttle being opened all the way.

Your bike is carburated, so I must be restricted on the carburators OR the throttle body (not being able to turn all the way)

no, there is no law that says you must. However they could believe you are riding it unrestricted and impound your bike. So it would make sense to carry something saying it is.

you could probably get away with a signed piece of paper from a garage saying it is restricted

well it would make over the legal limit so its pointless. 47hp is enough for 2 years. also, if you were to get stopped it would be obvious that it was modified.

@@adenlamb9916 how would it be obvious?

@@tinkertime7165 it wouldn't be obvious, you'd have to remove the carbs and take a look

as you can see theyre a curved triangle shape you have to buy the kit online, its £60 with the certificate

Yes, you have to remove/install 4 limiters, one for each carb

You will have to restrict the throttle or the ECU

+Simply Riding Tnx, found that set indeed. Also found a set from a German manufacturer, as I'm living in the Netherlands that may be better for me (includes a certificate accepted by dutch insurance). But, i may be able to manufacture the rings myself (at my technical university) if i would know the dimensions. Do you possibly know the dimensions of the rings for a GPZ500S? (or where i could find those)

No mate, here a link of all bike that you can restrict down for a a2 licence if your still interested www.bikechatforums.com/viewtopic.php?t=281627

Look online for r6 (your year) A2 Kit

Yes it would. You'd have one piston pushing harder than the other. an unbalanced engine will not do it any good and will likely destroy it

If you want to buy a certain bike, but it is over 35kw, and you only have an A2 license. Maybe when you get an A license, just remove it.

Money

Can I start off by saying you should be questioning if you can handle a big bike if you're wanting it to act like a 125cc. A 500CC bike will never act like a 125CC. Control of acceleration and feel of the throttle will be something you'll quickly learn in training. you need to be sure a bigger engine is for you. there is a large power difference, even when restricted compared to a 125cc. When you do your A2, You will be provided with a bike that is restricted and which passes specifications for an A2 License. You cannot change engine displacement, which means you can't turn a 500CC (Cubic centimetre) cylinder volume into 250CC. You can restrict throttle or air/fuel flow to limit engine power.

I am 100% sure accident stats would go up if you could buy any bike at age 17. a CBR1100XX with top speed of 180mph is only about £1500. just imagine how may chaas would buy cheap sports bikes like that and kill themselves within minutes...actually maybe it is a good idea...

@@adenlamb9916 cars do more damage to others and you can drive at 17 health and safety is too controlling

is soley so you have to do yet another test which means you pay more money to the government.

@@adrian69644 It isn't. The US has a higher motorcycle death ration under 25 per capita, as compared to the UK

@@aymanmehdi5323 that’s because they are all riding on the wrong side of the road😆

They won't. You have to officially write the change in the technical passport of your bike for the restriction to be valid.
