This is the point where I'm meant to say 'No, my mistake - it wasn't the lens - it does look odd & out of proportion..." I suppose......
But I won't.

A thought came to me today regarding these alloys.
With the newer 5 spoke wheels, the 17" rim and low profile tyre effectively gear down the bike. ie: each turn of the wheel is a shorter distance as you have reduced the circumferance. Check this by refitting the rear mudflap thingy and see the size of the gap (I've never seen one with the mudflap thingy retained as the gap looks silly).
I fitted the 3 spoke wheels ('cos they were cheap, mainly
) but I've noticed that they have not geared it down as the overall dimensions remained the same ie: bigger wheel at 18", but lower profile tyre.
Whatever, both types look great IMO

I think that the top of Adventure Boys bike is much closer to the camera lens than the wheels as the bike is on it's side stand and that is why it looks distorted!
Anyway, its a nice bike!!!

gearing
Paul the gearing is pretty much the same, as the original wheel size 160/80/17 on the rear and 180/60/17 on the alloy rear so what you would loose on the profile height is made up by the wider tyre eg 60% of 180 over 80% of 160 anyway riding besides Bumble Beemer on std wheels the revs and speed were almost identicle, this was one of my fears when buying the wheels

Don't think I'm having a go here, will you......I'm just thinking out loud.
Ok, so std rear is 150/80/17 so the profile height is 80% of 150mm = 120mm. Wheel & tyre diameter in mm = 17x25.4mm = 431.8mm (wheel) plus 2x120mm (tyre) = 671.8mm.
Circumference = "Pi"x 671.8 = 2110mm
Alloy rear is 180/60/17 so the profile height is 60% of 180mm = 108mm. Wheel & tyre diameter in mm = 17x25.4 = 431.8mm (wheel) plus 2x108mm (tyre) = 647.8mm.
Circumference as above =2035mm
Difference is approx 3.5% downward. Probably not that noticeable, really, but the above calc for the alloy assumes you've got the 5.5" rear & not the 5" with a 170/60/17 tyre.
Bloody hell, I've got a headache now. Must lie down. Too much work. Aargh!!
