Many thanks Fontyyy; again above and beyond the call of duty for your advice. I've got some reading to do now, need to do some research into these NSRs!
I do prefer them to the Aprillias that are also on my list; their rarity/trickness is something that really appeals to me (having to source parts for my bike/having them made specially has opened up a whole new field of motorcycling ownership. I'm not one for aimlessly thumbing through Demon Tweaks ticking off items on a wish list)
Saw 'Monkey's bike for sale on 400gb; if my RVF had already gone, I'd definately be interested in taking a look, despite the distance (I'm way down in Sussex). As of yet, I am also considering other non-stroker alternatives, but, everything's in the ideas/possibilities stage atm.
