Hi Kim, Toxy ZR and Speed Ross owner here; - though the latter looks set to be annexed by my gf of a couple of months Anne, whom I've never seen wobble on it yet (unlike some, Chris?) and who can already get up 1:7s without too much difficulty. (In fact I'm looking out for one on eBay so she can bl00dy-well ride her own bike in future instead of nicking my favourite one.)
