So I did a bit of research and found that for an A2 license bike, a motorcycle must be between 20-35kW of power and it can't be restricted by more than half its power. I also must have a power to weight ratio no more than 0.2.

So this got me thinking and I found that a K100 has a power of 66kW which could be restricted to 35kW and be legal, it also has a power to weight ratio of 0.14kWkg^-1 which is also within the legal range.

Sooo this made me think could I ride my motorbike at 19 which would be the dream rather than 21. Does anyone know if it is possible to restrict a K100?

This company thinks it's possible, but they're trying to sell restrictors.   Maybe somebody who has used one of these will chime in; otherwise, you could choose to be the pioneer.

It's probably possible but you might struggle to find an insurance company that would take you on, it's still 1000cc at the end of the day. They might be more open to a K75.

Sorry, I know that doesn't answer your question but before you do anything it might be worth checking out with your insurance company first.

Dave

Shouldn't be a problem. The bit that the OP didn't say is that the engine capacity has to be a minimum of 600cc (okay - 598 ). That's a hell of a price to pay for four washers and a bit of paper, but it's the paper you need for the insurance.

Just remove the two front spark plug leads.

Hellfire...!!! I've just read the screenshot properly - that's £179 for a piece of paper and a bit of tube to stop the throttle quadrant from opening fully!!!

My K100RT came with paperwork for restrictors......I didn't say it had them fitted.

I had no need for them, have a full licence since 1974.

So there is someone who sells a resticting kit. So the last and final hurdle.... insurance.

Now if anyone knows me on this forum they know my K100 is heavily modified, what insurance companies are best for custom motorcycles or does it not matter. In which case what insurance companies to people recommend?

I am with Carole Nash and have a multi bike policy. They also service the UK market. They are quite proactive on modifications and well aware that many modifications do not bring about increases in performance. Expect though to be told your ride must be secured in a locked garage, depending on declared value may look at what anti theft measures you have but you will generally get comprehensive cover with all that. A lot of the time they are more concerned with an increased risk of theft compared with a standard model.

My Ks are all insured for business use and for towing a trailer. In my case the modifications are tow bars, non standard panniers and in the case of the K1100 a Remus exhaust. The guys I spoke to have no issues with more heavily modifications but expect questions on increased power output etc

Carole Nash for all the reasons above.

I have been with Carol Nash for years, when I switched the area of my garage and only the K100RT, my insurance dropped from £389 TPFT to £150 Fully comp. Better than other insurance providers as they include things that are extras with other providers.

This thread now sounds like an advert for Carol Nash, . I'll give them a call then soon, as I turn 19 in a month and a half. But the bikes not even ready yet its all just hypothetical.

Not sure how it works in UK now but mine also includes EU wide breakdown cover. It is limited to 6 call outs per year in total on the policy, not a bad one as that's spread out over all the bikes on the policy.

It also is not age restricted to newer bikes, there is no maximum age for the bike.

A bike age restriction is common so you need to watch out for that. 

The only concern I would have is you are looking at restricting a non standard bike. In the small print here a restricted bike cannot be derived from a bike originally of more than double the A2 power....if you have performance modifications this may create issues with this requirement. You should get all your other paperwork sorted out as in what you have done to the bike and what effect it has on power before talking to them.

But if a standard K100 is 66kW could a custom air intake and exhaust push it above 70kW? Also for power to weight ratio I worked out I would had to have removed 82kg to become above the power to weight ratio limit, which I would be incredibly surprised if I'd done that. 

When you say paper work are you talking about dyno runs?

So I gave Carol Nash a quick call just to investigate a bit further, and they said the custom elements would be fine however they would not insured a restricted K100. So they're a dead end.

Three years will pass before you know it. In the meantime—speaking of restrictions—you can start saving up for the £12.50 per day fee for traveling in the Ultra Low Emission Zones of London which will be expanding south to Lewisham, and who knows where from there.

£12.5?! Oh God that's a lot of money... hopefully I'm too far out for that.

Adrian Flux was a no. Not looking good.

Hurray!! Well Devitt Insurance Company said they would not have a problem with a restricted K100, so thats very good news but obviously there is many other hurdles to jump through before I get insurance.

I've been with Bennetts for years and added my son plus his bike to my policy with no issues. Might be worth a call.

Thanks for the information, do you mind me asking what bike and how old your son is?

He was 18 at the time and his bike was  a 125cc with me as a 2nd rider. My bike is a 100rs, but they added it all to the same policy. Some one did say that the policy means he could ride mine but as far as Bennetts were concerned as that would be illegal it shouldn't happen as it would nil and void the policy.

Oh that is interesting and strange, is he still using the 125cc? or has he upgraded yet?

Carole Nash wont give you a named driver on a multi bike policy.

The reasoning is that in theory they could have both riders riding at the same time on a single policy. That makes sense.

It may be worth giving Peter James a call for insurance.

I removed my iABS system, and it didn't impact on the premium. Not as much modification as you have done of course.

Mike

So insurance companies being what they are apparently they're not allowed to quote me more than 30 days ahead, and I'm not 19 for 44 days so I'm going to have to wait two weeks then get quotes.

Thats very useful information though thank you because I do intend to remove my ABS in the future. If you wouldn't mind private messaging me about your experience and thoughts about it?

Look up a company call FI international - the do a k100 restrictor kit. I know because I had one and had the bike insured with AON and Carole Nash whilst it was in there. Basically the kit is 4 big washers that restrict the airflow at max revs. made little or no difference to the bike below 90mph. You need to get it installed professionally though to get the Certification,

Oh really? Why did you restrict it? That sounds really good. Do you know if they have a website I tried to find them but could only find a phone number, but they're out. How much did it cost you?

If I recall the Kit was about £120/130 and I paid my local independent bike shop €50 to fit it.

I had to fit it because my licence had lapsed and I had to resit the test and ride a restricted machine for 2(?) years. It made so little difference to the bike that I sold it last summer with the kit still in. Wasn't worth disturbing the rubbers for removal. I did several continental trips in company during that time - Fully laden for camping and never had any bother keeping up.

I did buy the kit onlline but I can find the company's website either

a search threw up this alternative:

Oh fair enough. I'll try them on the phone later or another day.

That other result you sent restricts the bike to 25kW which in the UK would be illegal. I'd need a 35kW.

Surprisingly not as high as I was expecting but obviously still stupidly high. I valued the bike at £4000 for reference.

I think they're calculating hospitalization, pain and suffering, and court costs into the mix, too.

No; they're just taking the piss. Worse than that, I'd guess that's just for third-party only. I'm used to seeing that type of figure over here where the excuse is still 'civil unrest'. Money-raking bastards - we haven't had any 'civil unrest' for over twenty years now.

Who gave you that quote?

Yeah you have a point Laitch but England is particularly bad for insurance for young drivers Dai's right. That was Bennetts, its fine I'm at uni at the moment so I'm just going to have to wait till I finish and it comes down in price.
