I think the front forks are nearly perfectly balanced for the big scoot. The rear shocks are bit trickier to understand. They feel stiff, but then when forced they do have a decent amount of travel. I have become more comfortable with the rear shocks and really don't complain about them much any more. There is still a sharp jolt from the rear when hitting large (should be illegally large) pot holes and such, but even on relatively smooth roads, the ride is superb.
On tight twistys, leaned over close to scraping, if there are bumps, you will feel the rear lost some composure. If it is smooth, it feels like a nimble sport bike. Overall, I give it a strong B+ or A- considering the length, wheel size and price of the machine ... not to mention its intended ride style.
