either she's one VERY BIG girl or that's a 1/2 scale Rocket III... I'm 188 cm (6 foot 2) and 120KG (265 US Pounds) and I look smaller than that compared to my Rocket III.
(cough) find a triumph rocket III and sit next to it..... apart from some of the V8 car engined bikes like the Boss Hoss it's the biggest bike you will ever see... there are some very serious proportioning errors here...
