Restrictor Kits - The Law?

[MattShill]

Right, I sold the CG last night (£725) so now I'm looking at bigger bikes in earnest. I'm actually having to get the school bus, it can't go on much longer. Now, I know somone who's selling a Kwak ER-5 with 4000 miles for £1200 which sounds like a good deal, and the insurance isn't as bad as I'd expected. The only unknown factor is the cost of restriction. Most delaers I've seen online (Bat Motorcycles, for instance) charge £150 for a kit+fitting if you buy from them and an obscene £200 for your own bike. However, I've seen kits come and go on ebay and the like, and I don't relish the prospect of paying through the nose for 2 small rings of metal.

Is it ok to buy a kit either new or 2nd hand, fit it myself, get it checked by a mechanic/dealer and then get it certified with the DVLA? The prices the dealers charge are rediculous, but is it possible to get legally restricted any other way?

I think the dealer has to fit it themselves in order to give you a certificate, the really annoying thing is it will only be in there for a short time.

Do your insurance company require proof of restriction?

Find that out first.

If not, buy a second hand set (let me know if you need some and I can give you a few links) and fit them yourself (with my instructions ). You won't need proof if the insurance company don't require it.

So long as it's legal.

If they do require proof, restrict it via a second hand kit and get a dyno print out (£30-45). They will accept this. But always check to see if they will - I haven't heard of it before but some may only require the official certificate.

PM me if you want any info on it, I owned an er5 and restricted/de-restricted it myself

There are other ways to skin a cat. You can retsrict bikes by placing things that prevent the throttle being fully opened (you could 33 hp restrict a bike by slackening off the throttle cable if you wanted to.)

Or you can place a restriction in your airbox-gaffa tape across the inlet works as well as any.

Another way is to glue some bits of plastic in your carb tops to prevent the slides from fully opening.

The 25kw restrictor kit for the XBR500 is a different throttle assembly on the side of the carb for instance, and thats from Honda.....

It states the bike must be restricted to 33bhp but doesn't say you must have a vaild certificate.

If i get pulled by police i can't see them saying have you got a certificate mate, If i got a producer i'm not sure

When i insured my RVF carole nash said that in the event of a claim i would have to show them a restriction certificate.

If the police are suspicious they will obtain an order to take your bike and dyno it.

That's great, thanks everyone. I'd wondered why there wasn't much official stuff when I Googled it, turns out there isn't any.

I'm with Virgin Bikes and when I asked for a quote they didn't even mention restriction, so I'll just have to make sure they're ok with it and it looks like cheap will be the way to go.

I bought the bike last night, btw, for £700. I kid you not. It's been standing for over a year but the motor sounds sweet as a nut. There's some surface rust and corrosion in places but a couple of hours with the wire wool and autosol have shown most of it'll come good. The main bargaining chip was the fact that it wouldn't actually go, so we brought it round on a trailer. It turned out that 4000 miles' accumulated road grime and chain lube had gunked up the side stand killswitch, so with some WD40 and degreaser it was ready to go. Rode it up and down the street last night, it's awesome, it pulls like an attractive man in a club full of loose ladies. All it needs are new filters and fluids and it should be ready for MOT. It looks like polishing will be high on my priority list for the next month or so though.

I've got the certificate for my ZXR, but when I had my spill the insurance never asked for it, and when the copper took my details he put me down as having a full licence.
