Restricting a SLR

[Boris]

My Son is on a 33hp licence and he is looking at a SLR650. I gather these come with 39 horses in the box as new but I'd imagine after 15 years some of them would have died along the way so it may well be legal as is.

However to be on the safe side I'd rather it had a restriction kit fitted.

Does anyone have one that either they don't want or can anyone describe what the kit actually entails.

Also is the same kit used on the other 650s?

Put it on a dyno first that way you will have proof of its Hp if its under 33

I think there is a cdi restrictor box for them, try german ebay , but TBH they aint gonna make much more than 33bhp standard especially now, so get it dynod and keep the read out

I know the NX650 restrictor kit is basically an intake manifold with a reduced inside diameter, not sure if the SLR uses the same intake rubber or a different version, but surely there must be one available for these machines.
