Hello

I'm new to the forum and am seeking advice on restricting a R80 GS (1989). I currently hold an A2 license which restricts me to 35kW and the R80 has 37kW on the paperwork (even though it must have lost a few gee gee's since)! So I'm hoping someone might be able to help me.

Cheers!

You can't do it yourself. You need to use an approved workshop who can issue the certificate.
Good one to restrict though as you won't notice any difference.
It's usually done with a restriction on the inlet port.
 
Anything will do, puta grub screw on the throttle cable and if your woried put it on a rolling road and get a print off. There won't be a kit as you suggest.... Insurance company say the responsibility is on you to restrict the bike but there is no certificate to say so.... Some of the modern bikes have a manufactures kit but not the old stuff.

Well, that's changed then. How is it down to the insurance co?
It's a legal requirement of your licence, not your insurance.
 
No not down to insurance company...... I asked them if there was a cert they required and they said no as there wasn't a standard cert, if you have a new model bike there will be a kit, but it is not for sure that it does as it says it will as there is no standard.... On the Dakar we had that had a stopper on the throttle body to prevent it opening fully, that was leagal as it reduced the hp, as would any stopper on the throttle.
 
Tricky one eh!? This stopper, is it "customisable"? That is, if I only want 2kW off. Or are they set in stone like the German kit that limits them to 25kW, which is to much of a restriction in my opinion!
 
I would just ride it as it is. After 26 years there is no way it'll be making the power it was rated as new. You could always bugger up the timing or carb settings... ;)

I did the same with an R60/6 when I had a restricted licence, and wasn't overly worried.

No was specific to the Dakar , but anything that shortens the throttle camm will do. Or take it to a rolling road...
 
Get a Dyno run done and then submit it to your insurance company as proof. I think you will find that 35kW is hopelessly optimistic on any R80 :D

wreford miles's R80 was fitted with a 1000cc conversion and a high torque camshaft and still only made 31.5kW on the dyno.

Insurance company do not want to see any cert.... They were clear on that, they were happy if you say the bike was restricted it was restricted, of course you were not covered it it wasn't and you were also breaking the law if it was above the figure.... But I'm. Sure a dyno print out is sufficient for the law.....
 
Always look at the worse case scenario, your insurance will be invalid if the bike you ride is more than the allowed kw power. Insurance companies and police if necessary will investigate the licence and if any restriction has been carried out line with your licence and relevant law. The chances are all will be rosy, but I have seen these investigations in the past.

Get a restrictor kit, damn expensive but the law is a fickle business !!

They are easy to fit, no more than 30-40 mins labour.
All the best :thumb2

No it won't.

Limited maybe, but invalid? :nono

Let's get real world here.....the only 'real' worry is potentially from Plod.....If (and that's a huge 'if') the op was ever stopped and plod asked for his license then questioned the power output of his bike, and he was able to show a dyno print out showing that it was witihn range for his license (an almost certain thing) then it won't ever go any further....no plod is ever going to take that any further and ask for the certification proving the accuracy of the dyno or anything like that!

The insurance company, as already commented on, don't give a fig either.......in the same way, they won't go asking for any more than the first level of proof (the dyno reading)

If you take all this nonsense about insurance being invalidated to its limits, you wouldn't even be able to change to a different brand of tyres......
 
If you talk to any Motorcycle riding school and on the DSA website it is quite clear that the bike would need an approved restriction kit fitted with certified proof.
This must be on headed paper from an official source such as a main dealer, official importer or recognised specialist in restricting vehicles.
Dyno certificates alone are not acceptable.

There are too many iffs and buts regarding this but i would want to know i am safe in the knowledge if i am involved in an accident or pulled over by Mr Plod i am LEGAL and won't have my bike confiscated pending further investigation. Insurers are aware of what is necessary to comply with the law as are the Police. i know many Traffic Unit Police and they are well aware of the Restricted licence laws and will enforce if need be.

Ride safe in the knowledge that you are riding 100% legally, you have just got your licence, don't leave it to here say and what ifs.
If in doubt call the DSA and speak with your insurers.
All the best,

Certified proof of what?

that means jack schitt if you take the bike home and remove the restriction,

surely in law the police would, via the crown prosecution service have to prove that the engine produced more power than the law requires, for the licence conditions, any certificate, or dyno proof is just there to put the police off from and the inconvenience that would cause in them proving the bike met the requirements, since an 80G/s is unlikely new to produce over the power level, then why waste time and money in trying to generate paperwork which proves nothing but enriches many,

use some common sense! ;)

You need a power kit to boost the bike up to 35kw.
