Dyno chart printout for the bike will do.

As long as the bike is 33bhp or less (at the rear wheel) you don't need anything. Some insurers ask for proof, but the certificates etc. don't mean anything in law. Its up to the police to prove you are doing something illegal, so if they for e.g. see you doing 120mph on your GSXR they are going to seize and dyno it.

If you do want something to wave at them a dyno chart is best as it serves the helpful double purpose of showing you your fueling and engine condition etc.

If a particular insurer gives you a hard time for not having proof try another, i was not asked at all by the insurer i used while restricted (it was bikesure i think, may have been carol nash)

Something as simple as a homemade throttle stop is totally legal as long as it stops you getting over 33bhp.

the good news is that BMW made their own 33bhp restrictor kit, or rather a throttle stop. so if you phone up your local bmw parts place they should be able to order you one.

Seen this confirmed in a couple of places through a google search, apparently it costs about £35 (not fitted obviously)

if i were you i would get that, fit it yourself and keep the receipt handy to show if the police that ask for it (very unlikley)

here is a forum where they are talking about it: http://www.ukgser.com/forums/showthread.php?111801-F650-GS-Restrictor-kit-!!(Again)

none on ebay, but the last one sold for £5  shows what it looks like too: http://www.ebay.co.uk/itm/BMW-F650-CS-Scarver-33BHP-Restrictor-/221384650032

its lucky as most bikes need inlet rubber washers that are a bit of a faff if you arent used to working on carbs etc. also the company that makes them FI international is the same bunch of thieves that are talked about in JT's link

this thing
