Vespa ET4 125cc Max power engine speed?

[ScooterDad]

I need to know the Engine speed at max power (7.9kW) for a forthcoming MSVA test. can't find it online - I can only find the US 150cc model.

It's a 1999 ET4 124 CC (pre-leader engine) Chassis no ZAPM04XXX.

Can anybody help?

Thanks

66mph according to the video but according to what ive found online the quoted top speed is 95kmh 59mph

you can to a certain degree increase the top speed by sacrificing a bit of pick up by chucking in some heavier rollers, 11.5gm seems to be a good middle of the road size,

why didnt you say rpm then at full noise 7750rpm seems to be it, but of course thats roller and gearing dependant,
as for what you are doing at 60mph is any ones guess,

Thanks for the link Matt B, but I'm not convinced they've got this right. the ET4 125cc model pre-99 has VINs beginning ZAPM04 and that page has ZAPM19 as it also does for the 150cc model... I've had issues with confusion between these models for buying parts etc before.

That said, I think I will quote 7750rpm and hope for the best...
