Other laws include Anti tamper, this will mean that you can't fix your own bike or add parts or even change your tyres unles you go to a main dealer
As an airgun shooter we have a form of anti tamper on some of our guns so that power levels cant be raised.If your gun goes over the legal limit your liable even though you cant do anything to bring the power down.So if your bike has remote throttle and anti tamper fitted and something goes wrong you get a ticket for doing 35 in a 30 on a bike that is supposed to incapable of that speed you will be liable even though there's nothing you can do about it.Bit of an arse isn't it
