Cheers gents. Jb...if she decided to quit...it'd be dead easy...as it is she's a pain in as much as she doesn't pillion often but does still enjoy it and still wants the odd trip. The Aprilia really wouldn't work for us. I don't need owt over 100hp...my 95hp AT had done just fine for 7.5 yrs...it is simply the weight that Im trying to get down...coupled with a full sized bike. Lots of options available and I'd hoped there'd be a light bulb moment or something that I'd missed....I'll likely spend some time around some showrooms with my trusty tape measure (always get odd looks off sales guys but knowing the minimum dimensions for pillion space means I can ditch some "choices" from the start without 'her' having to traipse round with me as she hates it.
There's a solution out there for us...
