Oil pressure :
car iddle setting is usually a tad under 900 rpm
bikes iddle setting is usually around 1500 rpm
Bike engines usually revs up to 10.000 rpm and up.
Their oil pump has to cope with these high rpm meaning they are either small or under geared or a combination of both, requiring for a higher iddle setting.
Low bars :
It is just a lower handlebars compared to the factory high-ish bars.
Planning to fit clip-ons at some point.
Over-square engine :
just my opinion but the shorter the stroke, the least destabilized it gets at lower rpm.
More cylinders helps too.
