I’d be a bit sceptical about it being a euro 5 thing because my Euro 5 125cc bike is not similarly effected, neither am I aware of any of my friends Euro 5 compliant 125cc bikes being affected.roadster wrote: ↑Mon Jul 10, 2023 8:57 amLatest discovery is that there is a very harsh speed limiter which effectively cuts out the engine at 50 mph. This is apparently a Euro 5 thing and not a rev. limiter. I'll know more when I have changed the gearing and installed a rev counter but in the present state I regard this as dangerous in any dual carriageway situation with following traffic and busy lanes. Its got to be fixed!
Happy if anyone can correct me otherwise though.
Maybe is it’s a limiter to restrict (sorry) the possibility of engine breakage through continuous high speed running. It is what it is in fairness.
