Lane splitting is no problem on the MP3 TTW. Photo of Blez driving shot from the pillion seat by Bernard Zieja. 2007

The front wheels of Piaggio's MP3 are only 420mm (16.5inches) apart, so lane-splitting like a conventional bike or scooter is no problem. Pic of Blez in West London by Bernard Zieja, 2007.

You'd have to be fairly bold to put a heavy two wheeled scooter into a full bore drift like this. On the MP3, it seems less bold.

Piaggio's MP3 tilting Three Wheeler is not an FF, but there has been quite a lot of discussion about it on the FF discussion list, so I thought we should have a few pix up on bikeweb for people to refer to. There's no doubt that the twin front wheels provide a reassuring feeling of grip and confidence on slippery surfaces and it can be heeled over to a respectable 'angle of dangle' before things start grounding.

Inspired by Philip Wakeham's 'Anything is possible' attitude to engineering art I woke up one morning and decided to implement Royce Creasey's aerodynamic improvement hints (see his technical paper on this site) and cut the fairing into three pieces, chopped four inches out of the middle, and reassembled it!
The narrower fairing has little impact on comfort, reduces frontal area a little, but amazingly has made the bike much less susceptible to side winds and the turbulent air behind large lorries, it is more 'indifferent' as Royce puts it.
