I have that exact "ATV" jack. They are less than $100 when on sale at Canadian Tire. I would drive my R3T up onto two pallets with a space in between left for the jack, then I used a square of hamster bedding between the jack and the bike to maximize surface contact area / reduce any pinpoint stressors. Worked like a charm to get both wheels off the ground for the winter.
My question is where under the bike do you place the jack. I have the one pictured and it grabbed the frame on my Harley. Kinda leary about lifting the engine in the right spots.
