33BHP - Do you need a certificate?

I've got my SV coming in the next week or so, got my test in about two weeks. I was wondering if i need to have the restriction fitted by a proper engineer so i can get a certificate.
I dont feel like splashing out a hundred odd quid more just for a peice of paper, especially if i dont need it. And with the guides on here i'm sure i could get it right.
anyone know the proper law behind it?

yes

Well, it seems to be a grey area. Insurance companies dont ask for it, infact, they dont even ask if you are restricted in the first place, even if you are under 21. But in the event of an accident, the investigating police officer may ask for proof of your restriction - this is where its important to have the certificate, and the support of the place where you got the bike restricted.

It may be that a dyno print out would suffice, showing your machine to be 33 bhp or less. I guess a police officer could take your bike away and also get it checked out for themselves.

Anyway, I paid the full monty and got mine restricted at a proper bike worksohp, with a certificate and everything - i dont want to even take a chance the long arm of the law!

yea, thought that might be the case. I'm guessing a dyno run would probably bump the cost up anyway. Thanks for the info.

I did it the proper way certificate and everything when I did this a number of years ago.

Personally if I had to go through the same situation again I would not bother. So long as the bike is legal (Ie it is restriced properly) and you have some way of demonstrating that (ie an ECU unit which is marked with the Suzuki part no. that is verifiably a restricted ECU) I don't see as a certificate matters much.

I did get stopped by the police during my restricted time. I was riding down the M1 with no lights (in the dark). They could have done me if they wanted to for that. They checked the docs I was carrying - including my license which showed I was restricted, gave me a producer for my docs (wasn't carrying insurance info) and a vehicle rectification note (for my lights) but did not say or ask anything about the restriction or any certification for it.

Having spent a day with the police yesterday, although I didn't ask this question, the impression I got is that this sort of thing probably wouldn't register on their radar unless you got into an accident and were a possible cause. In that situation though they would be more interested in breathalising you, because they are required to. So long as you had a license, tax and insurance I'd be supprised if the subject came up.

I would NOT ride an unrestricted bike on a restricted license.

My opinion only of course.

yea, definatly not going to be riding unrestricted.
Problem is the bike is a k2 curvy, so its going to be the more techy restriction. I can see the ease of having a certificate, but i'm just tight . That restriction is half an Ixil can....

Arguabley a change from stock can would invalidate the certificate anyway (not saying anyone would pick up on it just that the kits are for 'standard' bikes).

Being an old fart (27) I am concerend that anyone looking to save money on one aspect to spend on a can would end up in tears.

hehe, was just kidding. I've already now decided to get the kit fitted and get a nice certificate. Just wanted a few other views on it.
thankyou.

Hmm you go up in my estimation. Not sure that that's for anything, indeed it might not even be a postitive in the opinion of the masses but I thought I'd share that with you all the same.

Unfortunatly i feel i have something to live for. So a GSXR was out of the question. Secondly ive spent the last year and a half riding a 4 stroke yamaha xt125, top speed 69mph (down a hill with the wind behind). So riding illegally de-restricted didnt sound to clever. Lastly, I'm just about to become a special constable. So leaving my unrestricted (illegal) bike in the car park of leicesters main police station really was just asking for trouble.
All in all, I've got two years to save money for all the lovely bits of plastic and metal i want to stick to it.
