Hi, and welcome.
I don't recognise the bike as belonging to anyone in the club .. but others might.
Either way, its pretty.
As to whether 750cc will be enough ... well I may be an bit unusual (
) but I've had my 750 for about 12yrs and I still don't hanker after more power.
On the gearing, many folk seem to prefer the 14T front sprocket, but I've gone the other way and lengthened the gearing.
I'm currently on 15T front, 40T rear .... and I've just bought a 39T rear to try.
I think the longer gearing suits the bike .. but I guess its a personal thing.
And to be fair, my 750 has lost over 10kg from its std weight, which helps.
Anyway, hope you enjoy it as much as I do.
